what do you mean out of place? they allow any piston, any rod.
Maybe its a regional thing. I find it odd a class would allow a 48lb crank and any rod/ pistons, but limit the carb to a rochester and stock rockers.Quote:

what type of top end and cam would you recommend for this set up? pm me if you like.
vortec 2bbl can be used
Do you mean vortec heads?
What is the head rule?
Hyd or mech cam?
I try not to PM, what you need to know will help others.
23 degree cat iron head, vortecs are allowed, as well as mercruiser intakes which are near impossible to find where i live. solid cam/lifters, intakes are to be untouched
where can i get race ready vortec(both regular and bow tie) heads for a two barrel motor, what cam recommendations does everyone have, 1/4-3/8 mile dirt oval
