Thread: 292 Heads

Anyone know the flow numbers on a GM over the counter angle plug 292 head?

I got a friend running a set on on a 383 in a Chevy II Nova. He's running 10.90s using the cheap cast rotating assembly out of www.jegs.com and a Cam Motion solid roller cam .620/.620 252/257 106 and an old school torquer intake. 4.11 and 28" tire. Also a 2-speed glide and 3500 stall. All throttle No bottle. Just lite home porting, valve unshrouding. He's into the rev limiter 60+ feet from the traps at 7200 RPM. That car pulls so hard all the way through that when he chops the throttle the front falls 4-6". He's going to go to a 3.90 gear here shortly.

Anyway, I found a set fairly cheap but can't seem to find the port size or flow figures. They must be pretty decent though. That combo is working pretty good. He runs low 11s on a throttle stop barely cracking the rear barrels.

The secret is the cam....

Cam Motion is a high end cam grinder...they'll grind a cam to extract every ounce of power out of a set-up....we've had more than our share of busted blocks because these cams were pretty stout...

These custom grinds are all we use....

The flow numbers are @28 in. of water and .600 lift.On the intake side 201 on the exhaust side 177.These are stock un-touched flow numbers.I would make sure the heads have been maged.These heads are known for cracking.
