So, Andy. Do I have this right?
Can you complete the comparison?

Super Victor: 715 ft-lbs at 5500 and 830 hp at 6700 rpm.
Indy 440-3X: 715 ft-lbs at 5500 and 816 hp at 6700 rpm.
Indy 440-2_: with 4500 adapter
Mopar 337__: 800+ hp
Indy 440-2D: 7xx? hp (Dual plane port matched to Max Wedge)

Moparts member Drag Stripper brought over his 337 intake so we bolted that on and make a couple of pulls. It made a little over 800 hp, right in line with the SV, 440-2 and 440-3X. Basically all four of those intakes made the same power.

Yep, that is basically correct. The 337, SV and 440-2 were all right at 830 hp. The Indy DP dropped to 710 hp.

The 337 was gasket matched and blended on the runners. The plenum was opened up to a cut down 4500 adapter. Drag Stripper has modified that intake to work with his hood scoop clearance so he had a custom adapter on it.

I wanted to run my B1 intake but the adapters I have for it didn't fit quite right so we couldn't make any pulls.

I need to figure out what to do with the crankcase vacuum. I'm pretty sure I can pick up another 20-30 hp with a bigger dry sump pump and/or a vacuum pump. Do both upgrades will cost me about $2000 so that is a big chunk of change. I'll have to make a few calls to see what people recommend.
