Inliners International Forums General Discussion Engines GM 4 cylinders 151 153 181

I have one of these for a 8 port head...

I saw it on eBay. It would be a good buy for someone.

Here's something I found... This homemade dual intake for a 153 with the stock Siamese port head.I checked it,does fit.A bit crude but well made from steel tubing,welded and brazed.Has fittings for a small balance tube plus the brackets you see.
I'm not using it,might be of interest to you guys?

Yes, crude but interesting. With so few after market intakes out there I'm surprised we don't see more of this kind of stuff.

I finally finished my "Offey" intake and header flange for my 153.

Looks great! Now to get all the pieces in one pile. Jake wants to drive your jalopy.

NOW YOU,VE GOT ME LOOKING FOR A 3X2BBL OFFY FOR MY 181..... TO CUT DOWN TO 2X2BBL. I WAS THINKING ABOUT 2 S&S SUPER "E'S" HARLEY CARBS

On man's trashy intake is another man's inspiration.

The S&S should work, but the mileage will be terrible.
No high-vacuum cruising circuit.

IF IT WORKS ON A HARLEY IT WILL WORK ON A 181. I WAS GOING TO RUN 2 OF THEM. I HAVE 1 ON MY PANHEAD AND ITS THE CATS MEOW...

Depends on your definition of "work".
I accidentally started a H-D panhead by turning the engine over by hand with the key on.
Why unusual?
Because there was no carburetor at all - but there was enough residual gas in the manifold for it to fire.

My dad rented his body shop from the local Ford dealer. Once at the Ford dealer somebody removed a carb from a car, to be rebuilt the next day. That next morning somebody had to move said vehicle and jumped in and started it, not knowing there was no carb on the car. The fuel line connection was left pointing at the intake manifold opening - it lit off and away it went! Revved to the moon.

I have used the 153 for lots of projects. speed parts were available and inexpensive. the first one I saw at lyons drag strip in S.California with a Paxton (?) supercharger awesome! always wanted to duplicate that. here is the latest one a little experiment with a hypercharger for a motorcycle made an aluminum box to mount the unit with a weber carb Clifford intake and exhaust. the 1959 fiat will also have the same config. the '36 dodge and '36 chevy I will go with the 292 six. this next winter.

That sounds interesting but none of the links work. I want to see them. I have a couple of old McCulloch superchargers and I'd like to put one on a 153. The 153 is only half the size of the Stude V8 it came off of. Probably get all the boost you'd need to have a little fun.

LETS SEE IF I CAN GET THE IMAGE. thanks

Thanks! That is a different approach. I like it. What else was done to the engine? Do you have an idea of power output? Gain with the hypercharger?

hi there, the engine stock bore, mild cam head cleaned up a little. nothing too out of stock. just had the exhaust finished
this week. bed is bobbed about 16 inches to balance the short frame. everything is new except for the sheet metal. finally have a clean title! much more difficult now. as far as the hypercharger I don't know yet same for power output. powerglide trans is an electric actuator shift. experimental. I am ready now to bolt everything back together and send it to be wired. thanks-normanpaul

Let us know how it works out good or bad. Show us some pictures of the truck.

I am ready to actually begin the assembly of my '26 Chevy roadster. I am going to start a build thread somewhere. Not sure where yet but these threads seem to do well on the HAMB. Here are some pictures of some of the pieces I have gathered over the years for this project. LINK

That do be pretty -- all of it!

You have planned well, and you have assembled some mighty fine material. It will be a pleasure to watch it go together. To hear and see it run will be a joy.

Get on with it!

God's Peace to you.

I want a ride!

The Mallorys look like the best bet, I just got a HEI and the head is huge Dont think there is going to be enough clearance for the Distributor head against the engine on my 1972 l4 153 front mount Distributor location...Ps I have a 2bbl rochester 1972 carb that needs rebuilt anyone on here do it for a fair price?

If it is the tall HEI it will fit. If it is the short later one it wont. I'm modifying an early Mallory Pontiac V8 Duel point for my 153.

can you tell me where you got your header at , i know where to get the intake at i am trying to find a header combow i have a 181 that i am going to trun in to ciecle track motor for a s10 in mini stock racing big daddy doug

What was the end result of this build up with the 181? I'm looking to build one for my Jeep over the winter and would like to know what to expect out of it performance wise. I will be going from 2.5 AMC I-4 with an advertised hp of 117 to the 181. I would like to get around 200 hp and keep tbi. Any thoughts on this?
Thanks, Al

J45,
I'd like to see the photo of the 392 headed 151 Iron Duke. I did my Hemi headed Duke with a 1957 Desoto 345 head as the bore center spacing was better. 2.0" intakes, 1.75" exhausts, Edelbrock Fiero TBI intake with adapted 32/36 DGAV Weber, BW T50 5-spd, 3.42 rear, sleeved to 3.875" bore, stroked to 3.6" with MM crank, 292 rods, all in a 1978 Sunbird wagon. 40mpg highway, 20-25mpg city, '78 EPA compliant without Cat, air-pump, etc. And best of all it devoured V-6 H-bodies and even some 305 Spyders. Drove it 20,000 miles in two years here in Denver with no major mechanical problems.
Have you seen Nick Arias's two aluminum Hemi Super Duty 4-Bangers? Thanks in Advance, kalklein.

well, i've been trying to dial all this in had to change the water lines to cliffords specs, the "new" fuel pump leaks oil so that will need to be replaced. the pro shop had the weber carb all jacked so I adjusted it myself. changed the valve cover to a marine mercruiser with side pcv I think the vac.lines are all good. removed the hypercharger until everything else operates properly. the big issue right now is oil blow by pressure.
oil was coming out of the oil filler cap, replaced it with a standard cap oil started blowing out dip stick tube and distributer base and also fuel pump which I may have blown out the pin caps I do not know. other than that it drives and handles well. my plan this winter now is to maybe change the cab to a more modern 1936 cab havn't decided yet

header is a Clifford. it fits nicely I didn't have to re-work at all. sorry I don't get a chance on the computer too often to reply thanks-paul

In the Nick Arias shop.,

MM crank with 3.6 stroke, was that a 181? With 292 rods and 3.875" bore what pistons did you use? Why didn't you stay with the 4" bore? Interesting combination.

BotP,
I chose to keep the deck of the block and the head casting as free of weakening plugs and holes as possible. So I carved an adaptor plate out of 1" thick high-grade cast iron and screwed it to the block with many smaller flat-head cap screws. I then bored the plate with 4" holes matching the cylinders, bored the block plate/block (screwed together) 4.060" and pressed in a sleeves for a 3.875" ID, also the original 153 bore. There was a solid copper gasket between the plate and the block. Water passages were carved through and about the underside of the plate....
And for my next trick, the valve gear. To get the push rods from the lifters to the rockers would require bent push rods or piercing the cylinder bores and pistons, i.e. no direct shot is possible.
Eight 3/4" holes were drilled through the plate where the stock push rods would have most closely passed each other, the stock rocker push rod and the stock lifter push rod ends "intercepting" in the plate.
The hole was drilled to bisect the angles of intersection in both tangential and radial directions thus "eliminating" the edge loading. The holes were press fit with bronze bushings with 1/2"ID in which "slave lifters" about 5/8" long rode between the ends of the upper and lower push rods. GM lifters bled oil into the push rods for upper end lubrication. I drilled the slaves to use this oil supply for themselves.
The Fiero TBI intake had a vertical manifold / head surface; the DeSoto surface was about 25* from vertical so I cut a wedge shaped spacer to fit bewteen. The coolant return from the engine exited the head through this surface between cylinders 1-2 and 3-4 so I drilled through the intake plate, put in hose barbs and routed the hoses to the thermostat and radiator.
Oh, let's not forget the swapping of lobe locations on the cam for two-pairs. The cam was re-ground with a 60's 389 Pontiac HP profile.
Oil return was via external tapping of the standard corner of the head passages via hoses into the pan. The system was augmented by routing the crankcase ventilation through the engine to pull the oil down to the pan.
I ran this combo for two years and 20,000+ milea in Denver, -20F to 100+F. No major system or design problems.
Let me know what you think. KalKlein

Sounds like with all the work involved it should have been a racer instead of a driver. Neat project.

WOW! That's what I think. Nope drivers are my deal. You can drive 'em every day but you can only race 'em when the rule makers let you,
I just came in from whittling down an old Mallory Pontiac dual point to fit my 153 and was feeling pretty creative. Now I'm depressed. Oh well I got to play with the lathe and I didn't hurt anything. Well the Pontiac V8 guys may disagree but they will never see this.

CNC-D,BotP,
The line "Speed costs, how fast do you want to go?" ia followed by "If it don't fit, get a bigger hammer" and both are terms in the equation "Cost, performance, reliability; pick two".
I wanted to put the Iron Duke Hemi a '20s track-T because they are both narrow and the two foot x one foot chrome valve cover with the four plug wires disappearing down the middle sets off an alarm in most peoples minds. A Volvo 544 sedan would look cool with half-a-Hemi under the hood. I've got the motor torn down for evaluation (since 1989) cause most people still like big V-8s. Oh well, some day.
I've also got a Mic-5, 1:1 scale plate of the cast iron one in the engine. If I want to make another Hemi (a 181 would make a race strength short block) all I need to do is send a good machinist the plate and he would duplicate it; you could do most of the block work at home (other than the boring and sleeving).
But trying to find the DeSoto 345 head might be a show stopper. I found one in the Denver area.
We used to have a class of dragster called Junior Fuel, 5 liters, un-blown, nitro fuel, etc. Despite the hordes of SBCs the perennial champs seemed to the Adams/Enriquez DeSoto. It couldn't rev with the Chevies but it would burn the 98% nitro, can, label and all... and give change. The class is long since gone as well as many of the team members with their expertise.
I couldn't find anyone in Denver that had any porting experience with DeSotos so my head is totally stock. Extrude Hone would be my first choice to perk up my little 4 banger. It might be even more interesting than a 292 in my '66 Nova. (I could name it "the Morphodyte". Which part, the GM or Mopar, gives it that name is up for debate.)
If I ever get moved back home I might find my pictures of the little beast; I'll send y'all some copies. kalklein

CNC-D #5585,
No slight intended but I thought I could include you in the post to BotP. I couldn't; I am a slow learner.
I didn't feel comfortable with an Iron Duke bottom-end so I drove the p--s out of it on the street. Never dynoed it past 4000rpm but the torque curve was at 200 lb*ft and still a straight line.
kalklein

No slight taken, its a real work of art to bring two things like the Hemi head and the Chevy block together and make it all work.

kalklein, Thanks for sharing all this with us. What a great engine build. You revived my thoughts of putting a Studrbaker V8 head on a Model A block. A Stude-A- Baker.
It is sad that as the the old racers/roders go they take so much knowledge with them. Often it is because they think no one cares. I know where a DeSoto hemi is but the guy won't get off it. He'll be gone and it will get hauled to the scrap pile. Oh well I can't save it all. They'd just have to haul to the junk yard from here someday.

Beater, a guy over on the HAMB has had a few sets for sale for a while, I started to buy a set myself for a project im working on. He only wanted about $130-$140 bucks a set. I'll see if I can find the link for you.

Thanks Scott, I really don't need any more projects until I complete something. I'm starting to make slow progress on components for the 153/'26 Chevy roadster.

I bought a new reproduction 153 car type exhaust manifold...I never used it because it had a serious casting flaw about the size of a quarter on a port runner.It looks fine otherwise.
If someone here wants it for the price of actual shipping plus 5 bucks just let me know.

The 153 I rebuilt and swapped into my 47 Jeep CJ2A last year runs nice.The only changes from stock is a short tube home built header and distributor advance modification.12 degrees intitial,about 34 total and limiting the vacuum advance to 14degrees gives better throttle response.
.030 stock replacement pistons were sitting .030 down into the bore. So I found a GM .023 shim gasket to get a bit of quench.The Felpro composition gasket is about .055 thick
The aluminum timing gear is a bit noisy at idle...
The Jeep has stock 5.13 gears and the 153 is happy to buzz along at 55 MPH.
