I can provide the late model crank flange thickness if you need that The part I would worry about is the distance from the back of the motor to the flywheel flange distance Mr.Cab Racing and winning with Mopars since 1964.

Weigh that up against a crank spec'd out for what you want. More often than not the fuel crank ends up costing more. Alan Jones

I guess the question is whether a Crower 4340 crank will handle the odd 1,500 hp burst... or whether I need to order a custom EN30B piece... -------------------------------- Darren Beale Keith Black Racing Engines®

If it isn't too much hassle, and it hasn't seen a lot of abuse, I would go with it. The stress it takes off the block is quite a bit. On top of that, you will be hard pressed to hurt it if it is new, or low use. I had cap walk at 2432 bobweight. I put in a center weighted Crower crank and it went away. That was in a Mega block with cross bolts. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

Quote: Quote: The depth of the backside(transmission side) of the crankshaft flange to the back of the block is different(longer) on the old top fuler cranks than the stock later model(1962 and up) cranks are Several solutions as already mentioned, one not mention is a thin spacer plate between the trans and block to move the trans back from the crank flange any idea of what the difference is ..? maybe i could machine the flange thinner leaving a step register. .100 " longer in the back and .100" in the front for a bryant fuel crank As for the adapter rings I called kb and he said that he has them in stock and is looking at one in his hand as we talked on the phone so I ordered it . I waited a month and a half and it still never recieved it , so I machined one my self . A week later the one from kb shows up I think ATI sells the adapter also . 6.50 @ 226 MPH 4.25 @ 186 MPH https://www.youtube.com/watch?v=YX86DHGKBo0
