65-85 under.

The Mopar's have always been at a disadvantage. We are stuck running 50 and 60 year old intakes. They make aftermarket heads but good luck getting them. Very little to no aftermarket blocks or cranks.
I guess we'll struggle through.....

OK everybody! Let's have a pitty-party for all of the poor Mopar Racers! Maybe take up a collection.
At least the FFFord Racers don't whine.

Easy there Billy man, I'm just rattling your chain.

But you have to be honest, the Mopar folks have the least amount of parts to choose from. When you go faster than 75 mph, it takes some good parts and pieces.

Have fun and may the force be with you.

I would say Pontiac folks have the least amount of approved aftermarket parts.

Ya can put any of the B-O-P Racers on that list.
When is the last time a B-O-P Racer got a bigger cam or a change in the weight of the rotating assy.?

Let's go with M-B-O-P as the leaders of Stock oppression. Common issues for all four.

Regardless, we all try our best with the rules & parts we have. All of us have to be a little crazy for doing this.

No,no M! They've gotten more than their share of "handouts" over the years!

Unless it's a misprint,the B of the B-O-P racers have 10.5 compression pistons in 1971,1972,1973 on the engine blueprint specs.

I always thought the 1971 engines started the era of low compression pistons and unleaded fuel.But I might be wrong,as I was only 5 or 6 years old at the time.I know the O got low compression pistons.

When I was growing up 10.5:1 WAS low compression!

Wellllllllllllllllll, the B Racers DO have some friends in high places! AND some (most) of the "legal replacement" pistons DO have very advantageous piston dish volumes.
