Thinking of buying a spare. motor to build



Yes you can use a n/a bottom end, the compression ratio is going to be higher though. And DO NOT touch the bottom end.
 
its what im doing, got a n/a engine on the stand, 200 bucks in new gaskets and other odds and ends for it, picked up spare heads to port/ clean up.
 
You probably don't want do that.. Very seldom do guys have goodluck when they start messing with the bottom end.. Just get a good n/a motor.. And leave the bottom end alone.. There's a reason the big HP Turbo guys still run stock bottom ends..

JUST NO! like said earlier, dont touch the bottom end. or you'll just waste it. thats called a 200 mile engine.

your also gonna want a way to tune it when done. it should run on a gtp stock pcm, but a tune will help it out.

Someone told me that ZZPs world record car uses a stock l36 bottom end.
 


last i saw a rebuilt crate block was over a grand, for a short block, long blocks go up to 2 grand easy.

last guy here who did all the right things to rebuild his engine, machine shop costs and parts was also over 2 grand. why a used engine is the choice most of us make.
 
then you spend $150-200 and regasket everything and you have cheap new to you motor
