383 with max wedge heads

[Ron Kirkpatrick]

This old trick we did years ago before the aftermarket heads. Use max wedge heads on a 383. Hemi heads were used on 383 in pro stock in the 70’s

What did you use for an intake, way back when?
And, how did you seal the valley?

Interested on the intake as well. I used an indy on mine, had to get creative to seal it up. Won many a race with that, before she done blowed up.

This is a modified TM7 that I picked up cheap, already welded up to use on a 440 with maxwedge heads.
The manifold worked well but sealing the valley was a nightmare. After several that I fabbed cracked, or didn't seal/leaked, I finally cut the top of the ports away on a stock bathtub, ported what was left to match the ports, add used hand-cut gaskets on both sides of the bathtub ports. That finally worked.
The tarantula ran exactly the same with a 850 dp, as the stock max intake with two 750competition carters

Found a pic of what I did. The bottom of the intake flange and the valley tray were milled together. And then the little corner wings
