some will chime in but im pretty sure there stronger than most off shore cast cranks

i think there is someone on here with a 466 stock crank h beam rods and probe pistons in a mud truck spraying a 250 shot .

the weak link will be the stock rods that may hold ya back

I'm not an expert on the strength of the rods or crank. They each obviously have their limitations, but the crankshaft is plenty solid for most applications (with exception of all out race, or high revving pulling trucks) I have built several 460 engines (15 or so) and have never ever worried about the crankshaft providing dependable service. All but one of these were simply hot street, or pickup truck engines. I decided to build a "budget" race engine to play with at the local track. Stock crank and stock rods. I "massaged" the rods the best they could be (polished beams,shot peened, resized, added APR 2000 bolts, football head rods, balanced, etc). It was built with as much precision as I could muster.

After playing with it at the track several times and having better than expected runs, the only thing that kept me awake at night was the fact that it had stock rods in it. Hind sight is 20/20, and we now have the internet to look back at other people's mistakes. In my opinion, for what it cost me in time, money, and grief to put in stock rods, I could have easily bought a decent set of H-beams and been 10 times better off.

Properly set up and properly utilized, the OEM crankshafts have been run successfuly in 4-figure hp engines, as well as in truck pulling engines sustaining 9000 rpm.

So assuming you are building an engine that will have far less rpm and far less hp, and be kept in good tune and receive plenty or preventive maintenance, you ought not have a problem with the OEM crankshaft.

That was me. Stock crank, h beam rods, forged pistons, under ported d0ve-c's and I hit it quite often with a 2(0-275 shot. Only reason I hurt the motor last year was I goofed up and didn't pull enough timing Sad It will go back together as it was for my spare motor.

A 4.440 bore with a 429 stroke would be great right. With scj alum heads.

I agree w/others about the crank,BUT 250 shot and 40 yr. old stock rods should not be in same sentence imo. Smile
