What you want is the factory 792 crank. EN40, competition, came after the "red" crank...which was earlier cast iron job with nitride... Or aftermarket "steel" crank.

Don't mess with any "red" jobs...as you'll not be happy....well, you can get "same" with a stock crank and nitride on it...better than stock...barely....will wear better, but little added "strength"...

Still looking. Someone that has moved from HP to Limited prep 1275 has a used steel crank they are not going to use. I have new Carrillos for 948 and I cannot waste them on a stock crank. Dan 404-444-2161

don't waste your time with a "red" crank. Melted down battleship steel metallurgy will bite you in the tail.

Invest in a 4340 or similar alloy and so long as the journal radii are maximized...……...you should be in great shape. Carrillo rods and an accusump will save you huge $$$$$$ in the long run as well.

Regarding okies post on the AEA792 crank. I bought the last new one in the US years ago and snapped it at 8k on Taber Sr's dyno during a development test...……….so that is not good enough either. The only reliable piece I ever used was the Moldex 4340 billet I had made. $$ BUT worth every penny. Not a single plane so it looked a lot like a small block chevy crank....looked super weird but worked. J

A lot of you HP guys have gone to 1275 from 948. Smart.

There is a used billet 948 crank on someone's shelf they are not going to use. Please help an old (yes I'm 73) vintage racer out and give me a jingle. Broken cranks wipe out a lot of other stuff. Thank you. Dan 404-444-2161.
