anyone know the CR rating on my pistons int he l03? thanks!

 

Static is 9.3:1. Do you want to know how high you can go or what the CR is stock.

 

well im curious if i throw aftermarket heads on, what CR's im gonna get with different cc heads. if i throw 58cc heads on their is my CR gonna go up or down? and if im gonna need to upgrade fuel.

 

Your stock heads are 58cc so there wouldn't be any drop in CR.

 

oh cool.

is it hard to replace pistons in an engine? cuz i might do that.

 

Well it is easy if you know what you are doing and you have a fresh block. It may be time to pick up a book on re-building engines.

 

You would have to pull the engine apart to do it.

 

ok screw that, new sr torquer heads, edelbrock intake manifold and the biggest cam i can find that will work with those heads, 3" exhaust w/ headers and a nice chip should compliment my 305 pretty well eh?

 

and then of coarse, do little things liek 1.6 ratio rockers.. underdrive pulley, and my 3.73's i get later this week should be cool eh?

ill have a fast lil 305 on my hands

 

You are on thr right track but be carefull in your planning. research every component you specked out and find their limits and what it takes to run them. There is more to building power with the 305 than making a list.

 

i have researched all these parts over the last couple months, i know exactly which brand and everything im gonna get. if your interested i could list it all.

i know the specs on it all and im pretty sure it will all compliment each other. i made sure it all works with 87+ blocks andthe cam will clear the heads. etc..

 

Ok good. Preperation is the key and you seem like you are on the right path. I just didn't want you to fall into the build-up trap that many people get into. They run out and buy lots of parts and then find out that they are worthless on their 305.
