I've seen the 429 cranks on here, but I haven't seen any 460 forgings. Aftermarket only? I'm looking at a turbo build.

Thanks.

Yes Aftermarket only..... or you can stroke a 429 forging with a smaller journal.

It would take a hell of a bunch of turbo hp to break a stock 460 crank, how much do you think your goin to make?

Yea, your prolly right. With the journal overlap that those cranks have it makes them plenty stout. I was just looking for some extra insurance due to the fact that I'll be tuning on my own ( pale ). I hoping for an easy 800 hp, with the capacity to handle more in the future. Im putting splayed caps on my dove block and just figured I would get the short block as stout as I could. Something forged would give ma a little more peace of mind than a 40+ yr old cast crank.

A non raced and inspected cast 460 crank is fine at 800 hp..... your first weak link will be the block. You can always get a scat 4.15 stroker in a forging for a relitivly decent price, Call Adney Brown at performance crank up.

I still have my old forged BOSS destrked crank, if your interested I'll hook you up. It had a bearing spin on #7 so it will need ground. It was a 3.59 stroke with Chrysler rod journals. I even have the number for Diamond to make you the same pistons I ran with it.

Assuming good tune, 800 +/- horsepower through a production 460 crankshaft should be no problem with turbos. Assuming good tune, 800 +/- horsepower through a production 460 2-bolt block with a little ol' 3.85 stroke crankshaft should be no problem. Come to think of it, I've just finished collecting all the parts for my own 800+/- twin turbo build, which will use a 2-bolt block and cast 3.85 stroke OEM crankshaft, if that makes you feel any better. Cool

Mine made over 1000rwhp with that crank and a stock 2 bolt block. Other then some cap walk it was all good. That will be a lot of fun in a boat.
