Well, next year we will be racing Wissota Super Stock. When these guy's say stock, they mean stock. Briefly here are some of the engine rules:

1. Stock Chebbie block, not one of the race blocks, and of course cast iron. Only factory 4 bolt caps, no splayed main cap bolts.

2. Stock Chebbie crank, forged or cast. Must have a standard production part number. No knife edging or lightening other then to balance.

3. Stock GM rods, no aftermarket....Thinking maybe the new style "powder rods" with some good bolts?

4,. Stock Chebbie heads, max valve sizes 1.94" and 1.6"--No Vortech or aftermarket heads, no aluminum heads....We have a couple sets of 461 castings. Oh yeah, no porting allowed, the Tech guys have templates of the runners, both intake and exhaust.

5. Stock cast iron Chebbie intake, no marine intakes....We have a couple of the chebbie spread bore intakes with EGR provisions. Allegedly with the EGR circuit plugged it is a good flowing intake????

6. Flat top pistons, any brand or construction, can not go above the deck....

I've been away from Chebbies for a number of years, interested in gathering some input from all the chebbie engine guys.

Thanks in advance for the help.
