First engine build question

Why 150 or better? You can take a stone stock engine and add bolt ons and add a good bit, you know that. Good intake, carburetor, headers and distributor you can adjust mechanical advance on. Come on man, he's not building something to go racing here. He may not have the budget to do what you're talkin about. I haven't read every post, so maybe he does, but I try to approach it like someone is on a budget until they say otherwise.

I completely do agree with you though that if his budget allows he should get cylinder pressure up there. Does he have to? Not in my opinion.

And where did I learn that rule? Trial and error doin stupid **** as a kid.

If it were me....That's all each of us can say "depending on the perspective"...either of us are right.
For all he knows.. the heads are already 68-69cc and it cranks 160 after its together.lol

Short stroke engines can really use the extra snap. Stock is around 145psi. Not terrible, but not what I'd call high performance.
Happy Thanksgiving btw
