How much can a 302 head be cut and still be legal in APBA?

AND is the big plug heads and the small plug head the same CC's?

If you have the 14mm plugs you can cut the head to 25.5 cc's, the 18mm plugs to 26 cc's. The APBA site used to have this info

The world is a big place

SOME PEOPLE RACE WHO HAVE NEVER HEARD OF APBA. There are prop racing all over the world, with their own rules or lack of rules. There are Go Kart classes that are only bore and stroke.

I, for one, know that compression creates power.

For one of my "HAIR BRAIN" ideas, I'm adapting an electric starter to the 302. I want to make sure the starter will kick it over, if we added some compression.

Truth is: A cool pipe, cool head, cool starter and a cool cowing would change he appeal of a 302....and I like 302's

And, I have a trailer to haul them on!

Well, I know you have the trailer to haul at least a few of them.

The only testing I did was buy a new motor from Ric and raced it without doing any mods to it. The motor ran middle of the pack, and even with out best props we were a couple miles an hour off our speeds with our best motor that had been cc'd. So, I had this motor cc'd to the same specs that had been done on our other motor and we picked up that couple miles an hour we were missing. I can only assume it you mil it down more it will only help
