Sooo motor is a .30 over 4 bolt main forged crank, cam, roller rockers, high rise torquer II manifold with a 750 Holley Aluminum exhaust manifolds. I don’t know spec on cam. How high should this thing rev? 24 Pantera TRS with a 21p prop. Seems WAY under propped to me. Also any thoughts on the torquer II? Seems like a high rpm manifold not much mid range. Any input appreciated been a wile since I had something other then a stock 454 mag lol

Cam and valvesprings has everything to do with what engine should / can be rev’d too. And what power potential engine had.

Torquer and Torquer II not a great low/mid/or high rpm intake. Was just a response to get an aftermarket intake to fit under a typical Corvette hood.

i would say with that setup not knowing the cam and springs.... 5000 rpms what are your rpms wide open and trimmed out? What model prop?

It’s aluminum with pencil zincs, was freshwater boat. I’m salt so plan on changing it. What’s a good manifold to run?

Haven’t dunked it yet, been going over everything I see I don’t like. Hopefully this weekend.

i found this quote "24 Pantera TRS mirage 23p said to be 400-425hp would flicker 70mph light fuel 1 person. Two people with fuel 68mph was the norm." I think the style would be a mirage plus 14. 5/8 ×23.
🤔

That’s exactly what my thinking was, a 23 mirage plus. This 21p has to be screaming the motor.

Could be correct for your set up but maybe not. Try yours and then some others, see what works best. Friends and loaner programs usually cheaper than buying props just to test.

Yea definitely lol plenty of friends with props. Going to try a bunch this weekend. That’s why I was wondering how high to rev this motor.

The Edelbrock Air Gap is a tough manifold to beat. Check your drive ratio. It’s possible it has the 1.36 gears.
