I just though i would let you guys in on some info i was reading about. Well anyways i was reading about a carclub in carcraft. The club consits of a bunch of 10 sec chevy IIs and one wagon in the 12s na. The thing that caught my eye was that all of them were running a cast chevy lt1 crank and some of them were spraying around a 250 shot of nitrous. Does this mean that the stock crank is really strong? I know the rods can handle around 450 horse but what can the crank handle, some of these guys must have had atleast 500-600 fwhp. Anyways just rambling.

 

cranks are rarely the weakpoint in motors. Most people do it for peace of mind.

I say spend the money in rods and piston for the bottom end.

 

HP does not kill cranks, rpms and detonation kills them. As long as they are keeping the revs in check (<6500) and they're tuned well, the stock LT1 crank will survive a LOT of power.

My next setup is going to be a stock crank, Eagle 6" Hbeams, Forged pistons and a 200shot. Looking at around 600rwhp on the bottle.

I saw that same write-up awhile back.

Can't remember what they each had, but are you sure they weren't running cranks from early 70 Gen I LT1s? If that's what they were using, they're forged.

 

I am at 561 RWHP (700 fwhp) and am running the stock crank with no issues.
I wouldn't mind doing the upgrade though.
