Here is a pretty neat you tube video of some old M/P cars,
It makes me want to go build a "little motor"

Wow, thanks for posting that great video! Listen how slow those motors come down from revving because of the extremely heavy flywheels that these high-RPM, small displacment motors this class was known for. I helped restore a '62 Corvette about 10 years ago that was an old Modified/Production car with a Doug Nash 5-Speed and 6.17 geared Dana 60!

Wish I had video/audio of my (above) old C/SM car. I ran a 305, single 750 Holly, Doug Nash 4 spd and 6:20 Ford 9" Rear.

Honestly cant recall how high we turned engine.........around 8500.

Back in that era, I was still running a stock harmonic balancer, set up with MSD crank trigger ignition.

At a Medford,OR Div 6 pts race during qualifying at launch the balancer "exploded" !!!!!!!!! Took out aluminum water pump, crank trigger, front left tire, sliced open subframe, pieces through the fiberglass hood, etc......

Weight per cubic inch is the key. Most F and G/MP cars were 277, 288, or 292's. Some heavier cars were 300 or so inches. They use a de-stroked 4" bore motor. Ed Matsko's Chevy-A-Go-Go 69 camaro is probably under 300 inches. Runs SS/FM. My buddies from Phoenixville, Pa. set the G/MP record in about 1976 with a 2 door 57 Chevy wagon. Ran a 292 with a Nash 5 speed a 6.50 ring and pinion and a 50lb. flywheel. Went 11.33 at Suffolk Virginia. Cotton Perry ran a real fast and competitive H/MP 66-67 nova in the those days also.

Those cars were fun to watch.
