I've been thinking of going with a forged crank in my 350.
I've found a couple of 1182's that were 20/20 and suposedly ready to go.
For some reason I've hesitated picking one of them up.

Is a 20/20 under forged crank still stronger than something like a SCAT 9000?

I would say yes, did they re heat treat it?

If you use a crank turned any further than .020" you need to make sure they leave a radius on the crank and then you use chamfered bearings

We have used .050"/.050" cranke with a radius but you have to use ACL bearings in a street performance engine, i hesitated a little at first but the customer already had the crank and it was turned be had to go 50/50, the machine shop did it but left a radius on the crank and had it heat treated, no issues

Maybe this will help.

MATERIAL: TENSILE STRENGTH: RATING:
Cast iron 70,000-80,000 psi OE engines
Nodular iron 95,000 psi OE engines
Cast steel 105,000 psi strongest of the cast cranks
1010/1045/1053 100,000-110,000 psi high-carbon factory-grade forging
5140 steel 115,000 psi sportsman-grade forging
4130 steel 120,000-125,000 psi premium alloy
4340 steel 140,000-145,000 psi strongest alloy for cranks and rods

A 20/20 forged crank will be fine. :thumbsup:
Remember when we used to turn 400 cranks a .100" under to fit a 350 block?

Thanks for the help guys!
I appreciate it.:yes:

Big_red that's good info!:thumbsup:
