hey guy's i am in a bind with what to do over chooseing the right rotateing assembly for a 383stroker? here in the cold to bone north part of canada i have one place i can order all the performace parts i need.....

here it goes what i have looked at so far for the bottom end (3.75") stroker kit with a rod length of (5.7 kb dish) piston 10.3:1 copressoin with a /58cchead i imageine that it with what i see in the catalogue.the ratios change dramaticlly with chamber sizes for sure wow....

#2 assembly choice is a 6.0 rod length with a (srp dish piston )compression with 58 cc is 11.4:1 my question is whats the big difference with the piston heads?

you see this is the first stroker i have ever thought about building i am starting with a 4 bolt main LT1 corvette engine for this project it is going into a 80 chev siverado stepside short box.. i have the basics for the bore job and the die grinding and the cost but as per the norm i dont want to mess this up the first time out right.. I can get just about everything the parts shop order's most everything from the USA so i figured thta someone knows more about strokers that i ever will so thanks in advance.

Thanks richard that really helps me a lot in this time of seroious horsepower wants, i found those links really good to find out more that i needed to know being as this is the first stroker i have thought about putting together and i am deffinetly going to start running the numbers to see what type of LT1 that i have and i will let you know if it's a gen 2 or gen 1 thanks again for the info...

The new LT's have a reverse flow cooling system, so the heads are also different, you are listing the 58 CC heads so I would assume that you have the newer LT1 as thats what they came with. It's a good motor know some folks who have tricked them out and produce over 400 HP to the rear wheels. You can run a lot more compression in them also since they have that reverse flow cooling.
