Re: Bring back super/mod...
Growing up in the 70s, there was a pretty large contingent of C/SM cars in the Northwest, so this proposed class is very intriguing to me.
Seeing as I am in the process of turning my old 66 Acadian (Nova to our south of the border friends)bracket car into a Super Stocker, This could be a slightly different direction for me.
The idea of the spec head is a good one but the claimer aspect will be a little difficult to control with 3 different engine combinations. Wouldn't you just have the guys with one combination sharing a really good set of heads and just taking turns using them?
I think keeping modifications allowed to a minimum would be the best route to go, periodic random tear down to check cc's, valve dia and valve angles. If you have the field covered by .20 or if your heads look like they may have been messed with they go back to the manufacturer to be probed and checked.
If it was 4.060" max bore size and say 365 maximum cubic inches, it would keep the oddball big bore short stroke combinations out of it.
A flat top 5cc piston would net 10.28-1 compression at 365 cubic inches or if milling was allowed, 60 cc chambers would net just over 11-1.with this compression, a properly prepared short block with roller valvetrain, stud rockers, 750 cfm carb and a cast manifold should be easily capable of low 10s or high 9s at 3000 lbs.
Teardown would consist of pumping the engine, pulling a head and ccing ports and chamber, check valve dia. and angle and check bore dia.
As far as the clutch actuated shifting, I know there are a lot of super stock cars that have gone to clutchless transmissions and really, how many stick stockers touch the clutch pedal on gear changes? My opinion is as long as it is a non planetary transmission it should be allowed.
If this becomes more than a pipe dream, I may have to have a change in direction!
Oh and one more thing....no sandbaggers!
