stock lt1 crank
how much horsepower is a stock crank good for? i was thinking of using a custom splayed 4 bolt main block, stock crank, with forged pistons and rods on a dd motor with nitrous.

There's a guy on turbomustangs.com that's making 680 rwhp through a TH400 using a stock SBC cast crank. He's running ~22 psi boost plus a 75 shot of nitrous and gone 9.7 at 141 mph. Also keep in mind that the stock LT1 crank is stronger than SBC due to the undercut journal radii.

i have a 355 on a 300 shot, the crank is holding up nicely i have eagle h beam rods and forged pistons strapped to the crank, but it hasnt let go as of yet... i want to attempt a 9 second pass on the stocker

My crank broke with about 50k on the clock... But since ppl are running over 400rwhp on the stock crank Im beginning to beleive it was a manufacturing defect or major imbalance. The engine internals were completely stock except for 1.6rr's and lt4 springs.

I agree yours was a freak failure not the norm atall. There are 3 10 second stock shortblock b-bodies two heads/cam bottle one heads/cam/blower bottle, only one is a stripped car and it is still 3400lbs.
If you get down to WIR say hi.
