My mates and I are getting an f-body roller for fun soon, I'm in charge of putting an engine together for it.
I want to make an SBC 302 with a 350 block (2 or 4 bolt mains, large journals), and 283 pistons, connecting rods, and crankshaft. There aren't many screamer small blocks around and it sounds like loads of fun.

This one is mainly going to be built from junkyard parts and the like to the keep the cost down. I usually work on motorcycles, so V8 pushrod engines are a little new to me.

If you want to build a motor that revs, worry less about total displacement and more about optimal rod: stroke ratio, correct head size and flow as well as compression ratio desired
Dominic Foster
You use the 283 crank. The pistons are too small. It's 4.00x3.00 bore stroke. You use 350 pistons

Ignore him. He knows literally nothing about building engines

I'd avoid TPI, especially if you're trying to build a screamer. Can't breathe much past 4500

Only small engines are able to rev past 5l rpm, no one is able to make power at all past 7k with things like a 460

Optimal rod:stroke ratio, head size and flow characteristics noted. I guess I'll go as high as I can with compression on 91/93 pump gas.
Just 283 crank and rods then? I'm glad I can keep the 350 pistons, makes things cheaper.
So carb it is!
Open question: Any carb and and head recommendations?

Which f body you looking at man?

>>Am I missing anything? things like squish, compression, port size, runner lengths, cam spec are super important to making it sing. that's not to say you won't get lucky throwing justsomething together >>Would the use of hydraulic roller cams effect how high the engine can rev? i'd definitely go solid for a screamer >>Should I go carb or EFI? up to you, efi is technically better but i can definitely see the appeal of carbs >>is there anything you recommend? nope, idk enough about chebbys to say. but large journals are more of a hindrance on a short stroke, NA, high rev motor if you can get a 4340 small journal crank
