Cast crank for Super Stock?
 
Hi All. I want to jump in with you guys into Super Stock with a slightly oddball combination that does not have a steel crankshaft. This is a small V8 so will spin reasonably fast. I possibly could destroke a longer stroke steel shaft, but it would be quite a bit of effort.

Just looking for similar ish experience, which clearly is not directly comparable. Do the 289 Ford guys use a cast crank and does it hold up? Other combinations?

A cast one is fine.

Built quite a few 680 -720 HP Bracket race BBC with cast cranks 2.200 rods. Turned a few to 2.100 rod journal for SS. The 2.100 eventually cracked.

Ken, If I am correct in my assumption about the combination you are talking about, you could find an ArmaSteel shaft which would be somewhat better. But in any case, the cast crank will be more than adequate and will survive the 8000+ operation range you are anticipating.

I see in the Indy thread that 2 of the 4 stockers in the barn are Pontiac. Does anyone know if they are running a cast crank?

I ran my 455 SD Pontiac in Super Stock, and it has always had a Cast crank/ The rules for SS allow you to run an accepted aftermarket crankshaft, so that may also be a option.

Thanks guys. I'd already started down the road with a stock cast crank, but just started to second guess myself. Time to keep going. Dwight has assumed right on the combo, and unfortunately there is minimal aftermarket support, and no cranks are available.

Kip Martin ran a cast crank and stock rods in his Super Stock Mustang with no problems at all.

I know for certain that the J/SA 400 Pontiac has a stock cast crank.
