Stock Crank HP????
Just wondering what the stock crank can handle? It's an LQ4 that will soon have a T76 front mount. I will be upgrading to wiseco pistons and K1 rods. Now just worried about the crank. Some people told me that it can only handle 600rwhp and some have told me 1000rwhp. Can anyone elaborate? I know I should upgrade it but I really don't have $2000 for the forged Lunati. If possible post up some dyno sheets.

MANY have made over 1000 on the stock crank. We have, Harlan went 8.20s @ 16x on a stock crank, some fella over seas just made 1300 hp on a stock crank.
A single 76 with NO wastegate couldnt break a stock crank. You will be fine

I've had stock cranks in my street car with FI for 30k miles and never had problems with them. I'm planning on 800rwhp this time around with my latest build and still on the stock crank with ZERO worries.

I'll be using a stock crank in my build, polished and straightened. Lingenfelter will be doing the work and both they and EPP said it should be fine at my power levels (700-800 RWHP) and both of those shops know a little about LS1 forced induction.
FWIW, I'm a 347" with a TC76.
