Crankshaft Strength I am building a sbc for my 2nd gen f-body. The motor will be putting out 500ish to the crank and seeing 6500 rpm off the bottle.
my question is will a steel crankshaft hold up to that kind of horsepower? is a forged crankshaft in my future?
ive just read and heard many different things and wanted your opinion.
thanks everyone

I had a stock crank (cut 10/10) and stock rods (ARP bolts) with TRW pistons in a 406. It was making just shy of 500HP. I ran it for a few seasons and it saw a lot of street miles. I sold it to a guy who continued to run it and then put a plate system to it. I think the key is prep and assembly. The machine shop that built the short block only does race engines (lots of 7 and 8 second cars). Even if you buy the Scat crank, have a good shop check things over and assemble the short block.

this is where the dilemma takes place. steel cranks say around 500 ponies max. some say it wont hold. some tell me things like you just did and persuade me.

Verdad Gallardo Well, they are not a sponsor here, so i really am not supposed to let Ken mention it, BUT, since none of our other sponsors carry THAT particular crankshaft, i can let it slide.
