Not convinced to choose one above the other.

Nice hidden plumbing In Wayne's manifold. I'd rather have it up in the daylight, you never know when there's a leak.

Never saw "Corvette summer" I'm afraid. Although "American Graffiti" is on my shelf...

Yeah, yeah. Morrison is one. There's a couple of others. The carbon trumpet manifold I think was used in OZ V8 series as well. I think 8000$ or so. Not in my league, I'm afraid.


OK, Bob. We agree, then at one point "To make more power, I would need to go with bigger heads. But, bigger heads won't match the IR system - tried that. For bigger heads and ports, I need a common plenum. Speaking from experiance, not theory. YMMV." : High rise 4- barrel for max Hp. But: how will the switch from your 8- runner to 4- barrel affect your Hp and torque curve (not the maximum reached), and would the driveability of the veichle be altered in any way?

The curves you posted in the IR bore size- thread shows up steady rise & flat at the top. Would a 4- barrel show flat, flat, very steep & a peak?
