What makes a SS car to fit in the modified class ?

Modified motor!

SS is HP to weight, SS Mod is cu in to weight.
I'm running a "hand me down" comp motor. Trying like hell to get it on the track.

Would a 300" Small Block Chevy with the Dart Buick Heads fit into any Super Stock Class? This is an old comp motor.

Yes, it would fit in any GM application depending on the number of carbs.

Also the Heads castings maybe an issue. Good Luck

I think it would, but contact the D1 tech director, Ryck Campbell to be sure.

SS/ Modified, C/M thru F/M, all heads must be NHRA accepted, 2 valves per cyl. OEM casting with OEM # cast in head.

NHRA rulebook, sec11F page 23.

The Buick Dart head is an accepted cylinder head.
The head was manufactured by Dart for GM with a GM part number.

It is still a great cylinder head for small CID engines like yours.

You can run in SS/BS, with one carburetor, or, SS/CM thru SS/FM with two carburetors.

Thank you guys. What would I have to weigh with that 300" motor and an automatic in SS/EM and SS/FM?

Not sure how the percentage for the automatic works when it says 11.50-12.49 ect.. Do you go off of 11.50?

Based on 300 CID:

SS/EMA: 3277.5 lbs
SS/FMA: 3562.5 lbs
