Hey everybody, I havent been on here in quite awhile. I ended up selling my '75 GMC(family matters) and just picked up a '78 Chevy C10 w/250. I am looking at rebuilding the engine and adding a bit more go power and still being able to pass smog. My questions are:
1)I am going to have the block decked...how much? I dont know. I want to use 307 pistons to bump up the CR....But how much will it bump it up?
2)I want to enlarge the valve size in the heads,port match and clean up the runners and CC. Will 1.94x1.60 be OK?
3)What cam would be smog friendly? I have a cat and EGR valve. and for the smog test will be running the stock intake and carb. I am looking at putting TBI on it later.
I plan on balancing the entire assembly. I am running a 4spd and 3.73 gears. I plan on towing my BBQ trailer(1000 lbs).
I know there are more details I am missing, but THANKS for any help.
-Lance
