so i have a motor that im trying to build for a turbo set up. I was gonna run a forged 4.00" stroke cranks and shoot for the 383, but doing some searching i found the stock ls1 cranks have held up, up to 1000hp. also after searching around i found the stroke on the 5.3 cranks is the same as the 5.7 cranks and people have swapped them out. question is do they hold up as well as the 5.7 cranks? only reason i really ask is because im building a seperate motor without disassembling the one i have or else id just use my old crank and i saw one for sale for pretty cheap. thanks!
