Where do Sealed motors run?

Dick Butler · 11-07-2015, 08:18 PM

Wanted to see rules, tracks that participate etc in the sealed motor class. Not IHRA or NHRA. NMCA? Thanks

around my neck of the woods mostly all the dirt tracks (Wayne Co Speedway, Hilltop Speedway, Attica) have classes for those, none in drag racing that I know of.

Pretty sure it's a round track thing.

NMCA Chevrolet Performance Stock and Chevy LSX series with 525 hp LS sealed crate motor. Heads up - low 10's. Also NMRA Mustang deal.

Nmra coyote stock. Very good class

Thanks, I will look up their schedule and rules...

IMCA dirt track uses a sealed 350/355hp motors in hobbystock and sportmod classes or what they call a 602 crate. They come from GM with twistoff head, intake, oil pan and timming cover bolts. They also have cable ties on other bolts that make them IMCA legal. They also use a 604 in the A mods. But like everything else it who you know there are many enhanced motors out there. Tom

Yes, the enhanced 604 crate motors out there make about 60hp more than the best tuned factory GM 604 crate motors, the twist off GM 604 bolts aren't hard to find.

Yeah, "sealed" motors ain't sealed. I've heard some of them that sounded like high compression small block Chevy Super Stock engines, and even Modified class engines. Those usually were considerably faster on a 5/8 mile track than the engines I knew had been tuned and tweaked, but not opened up.

One of the guys I know well runs a dirt class with a "sealed" crate 602. They all seem to have been "enhanced." Brezinski and others offer a number of cheater parts. There are suppliers selling replacement sealed bolts etc and a couple of builders have perfected methods of cheating. The local tech inspection is rather loose and fuel is also a potential cheat. (oxygenated and methanol).
