Inliners International Forums General Discussion Engines Six Pack for my 235?

Ok, so I've had an Offy 3X1 Intake sitting for a while to go on my 58 235 in my 53 Chevy truck after messing with rebuilding rochesters and them still leaking I've decided I don't wanna go with them. I just talked to Tom Langdon and he recommended the Carter/Weber two Barrel that he sells my understanding is that it's similar to the Holley/Weber that he has that I've heard a few including my buddie 57Mike have used on their inlines with good results except this version is a little smaller so it should work better for my 3 carb setup.

So the question is what do you guys think? Am I crazy or will this work and run good on my fairly stock 58(car) 235. I do already have a split manifold and flowmasters installed, A PCV System, and a T5 Tranny and newer rearend.
Tom didn't seem to think I needed to change Cam's at this point he said I can if I want but that I would be trading the streetablity of the setup off. He estimated that these carbs move about 200CFM If you rate them like a 4 barrel (he said). Anybody know what model these are or has anyone used em?
Thanks,
MONGO

I had Langdon modify a 2 pot Offy intake for tri-power and got his Carter/Webers, linkage, distributor, headers, and aluminum side cover. Haven't got them on yet. My cam won't be stock but he mentioned that the setup could be run on a stock motor.

Thanks for the reply 51 El Plymino I actually searched first and saw your post about the El Plymino setup just after I talked to Tom, I've got that first picture printed out and was showing some of my local buddies your setup to see what they thought, all were very impressed.
I love the looks of that whole project, a good friend of mine had told me about doing something similar to a totaled Pontiac he had back in the 50's he used it as a pickup for many years.
Do you by chance know what the model number of those carbs are, I've decided I'm gonna put the call in to Tom to get the order on the way tommorow but the only thing left I'd like to check and see if some of the carb shops have pieces for them like diff, jets and such if I need to tweak them once I get em, or are these carbs White elephants that no one's ever seen before.
Thanks,

Mongo, my friend has a dual Weber setup on his 261. Shaved and professionally ported head, full race cam and balanced lower. He had dual Rochesters, and hated them. Between my research and Tom's help, we convinced him to go with the Webers.

He likes the setup, good torque and a streetable engine. We are guessing around 230 hp. But not quite enough carb for his likes. Looks like I might end up with that engine in my 52, he's now building a 383.

I think the dual setup would be a better match for your 235, for one thing you will have to notch the firewall to put on the triples. But they will be different.

Hey Mongo: Langdon has everything you need for the set up. Ask him about jets,etc. He's the guy who knows all about these. The carters are smaller cfm than the holleys so its not too much carb for a 230 with a cam. He can advise you. I may have to notch my firewall an inch or two but no big deal for what I want to accomplish.
He has various air cleaners also.(old style Bell spun aluminum and even Harley ovals that would sit crosswise.

I won't know if the firewall will need cutting until I remove the two outboard choke assblys.(only going to run the center choke). They are about 2" wide and do take up some room.

Thanks guys,
Yeah, the firewall clearence hadn't occured to me till you mentioned it, kinda shortsighted of me, the old rochesters looked like they were gonna fit fine, I'm hoping I can pull the chokes off and make it work but who knows, might have to break out the BFH.
I'll post some pics when I get things together..
Thanks again,
MONGO

My Carbs came in and I see that yes I'm gonna have a little issue with the clearing the firewall so we started working on it.
We removed the choke from the rear carb that gains a bit. Then started looking at the linkage and decided that without the choke we could shave some off it to save another 3/4 inch or so, So my buddy Rick the master fabricator tore into it, Accross from the hookup from the linkage is a hole that is centered on the ball for the linkage, so we took an extra ball that came in the Langdon's linkage kit along with a nut that was in there (fit perfect) and welded it in that hole. Now the linkage hooks up about 3/4 inches from where it was before. This should get us close. We'll prob still get the Hammer out and make a controlled dent in the firewall to give extra clearence so it doesn't bind up. Here's pictures..





Thought those might help you with your modifications.

KC: post a pic of the setup when its done. Don

Saturday I got to work in the garage for a while and now have my Offenhauser 3X intake and my 3 Carter/Weber progressive 2 barrels installed. I did end up having to cut my firewall to make the back carb clear but it's not too bad and I'm gonna fab a box up to go in that space when I do my firewall cleanup here soon. I still need to do some tweaking on the linkage and the fuel lines (Not installed in these pics) But I got to fire it last night about 10 and it sounds great. It wouldn't idle so I need to make some adjustments but I think it's gonna be pretty mean when I get it all wrapped up.



O' and for the guys who don't know me this is in my 53' Chevy pickup with a 235/T5 combo and an open rear end.

Mongo

Ok, so last night my buddy Rick came over to help me do the final tweaks so we could get the truck out for a testdrive with the new carbs. Turns out it wouldn't idle because of 2 vacumn leaks I hadn't notice the night before (it was dark and I was sleepy) we plugged those up and it idled out nice but a little fast. Turned all the idles back 1/4 turn and adjusted the linkage on one carb that was not bottomed out and hit the road. With the 3X it's like a night and day difference!! More power, rev's faster and cooks right on down the road. I got rolling scratch on accident pulling out at one point! Over all it's a huge change I'd recommend to anybody running an inline.
Today I ordered the HEI from the Stovebolt company, it should be in friday or so more info (if anyone cares) once I get it installed.
So anyone got any cool aircleaner idea's for me?

MONGO

Mongo, you read my mind on the air cleaners - my only criticism of these Weber clone carbs is that no "normal" air cleaner can be found. Tom had some custom Stelling & Hellings type filters made for the Holley Webers, what does he have for the Carters?

Maybe you could rig up some foam sock type filters like Harley flat trackers used to use (probably still do). Just a thought until something better comes along.

I can vouch for Mongo here. This is a really nice setup!! It has made his Banger run quite a bit better than before. He is going to dread the day I get my GMC together! (rib rib) Way to go Mongo!! Nice job!! The idle on this is smooth as silk and seems to have really good power well up to 4 grand! He gets nervous after this point. :-) It really rolls along with the T-5 and later rear axle.

The HEI setup is great, I just installed one this last weekend. My truck drives and feels a lot smoother especially at high'er' speeds.
I did run into a couple problems with the install. Check out the 'HEI distributor coil type' thread. The problems I did have were slight, but now that it's done I have absolutely no complaints.

Mongo,

Nice job, it sounds like you are experiancing the real power of an Inline in heat.
Your photos are not posting. Check on your posting.

As you might be aware, I also have a 3x2 set up but on a .040 over 292. I used the Holly/Webers from Tom and yes, he is the man when setting these things up. I have changed my jetting too. I have 51's in the primaries and 54's in the secondaries. It does idle high (900-1000) but I like it that way as I am rarely stopped! I used a Lokar Cable throttle cable which works fantastic. I did not have to modify my firewall as I have about 1/2" clearance with my Offy intake and Hellings air cleaners. Make sure the carbs are turned the right direction on the adapters. I believe Tom said to put the throttle controls at right angles to the valve cover and to the rear(facing firewall) This is done due to the proper float position. You'll experiment with the best throttle response, lag, performance and do some tinkering. I have electric chokes on mine and have them all hooked up. I did disconnect the rear choke arm as it was running way too rich on warm up.

Great job and keep it Inline!

Do you gents run any type of "heat" to the manifold or is this really a necessity?
I've seen some kits out there for the Offy intake but I'm not sure whether I need this or which one would be best.

Thanks,

Tom

Tom,Here in the East Mid-Atlantic area I would recommend it. If your driving your 3100 in winter or those frosty fall days without the heat on the manifold there is a good chance your carb(s) will ice up. I had a '68 250 that drove me nuts on I-95 on the way to work. I couldn't keep the carb warm enough.After while the NJ State Troopers had me "profiled" : and quit stopping to see if I needed help as I sat on the side of the road warming up!

Yes, The intake is water heated with a plate that Stovebolt Engine Co. sells. It's almost mandatory to use if you are on the street!

I'm on the case. Talked with Tom yesterday and today. He sure is a likeable fellow.

Also, had some Magneflows installed today in place of the resonators that were on the truck. Big difference in sound. It's really sweet sounding now and I don't scare little old ladies.

Thanks,

Tom
