I look forward to the DP results. Thanks for sharing.
Let's just say it wasn't a good idea to run the Indy DP on this motor! We lost 100 hp and the EGT readings went wacky. Now I need to pull the plugs and check for damage. I tried it, but in hindsight I should've just left it on the shelf and stuck with the race intakes.

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) Quote:
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.

Great Post Andy, I was gonna ask if you wanted me to ship you my 337, I'm glad you found one. was the 337 OOTB or ported? As I mentioned in another post the 'as delivered' 337 ports are only about 1/2 way between a 906 and a real Maxie, the 337 does have excellent taper from the plenum as delived though. Please reiterate how much you felt the top-line Jesel valve gear/timing belt and dry sump may have contributed to the overall performance. I'm thinking somewhere in the area of 50-60 HP @ 6000RPM compared to a conventional wet sump/chain 'flexi-pedestal' system. I would say OOTB the Indy 2D would definately be a mis match, but when you port it right that will narrow the performance gap quite a bit, and of course running the same Dommy with an open 4150/4500 adapter on a true dual plane would probably Skew the A/F and EGT's quite a bit....even still I'll bet the 2D torque (with the optimum jetting) between 3500 and 5000 was pretty insane. If those EZ-1's worked that well with that 'not so great' exhaust port, I can only imagine what a full tilt -1 or equivalently MW intake ported SR would have done  I'm probably not the only one who would really appreciate seeing the corresponding Dyno powerband graphs; peak to peak numbers are cool and all but it's really way less than 1/2 the 'big picture' of how components perform against one another.  Looks like the 337 is the only viable "fit's under the hood" big single....you've inspired me to start porting it to get it to full MW size cause I think we can make up that ~15 horse deficit pretty quickly. It's even more impressive knowing it's a 4150 base which you would think puts it at a severe disadvantage to the 4500 flange competition.

Looks to me like the starting point was in line with what should be expected power wise. I'm betting the Hp gains shown so far are accurate, and the motor will run the ET numbers to back it up.

Wayne,
I take all dyno numbers with a grain of salt. I don't know how 800 hp on that dyno compares to another dyno. But I do like the back to back comparisons of intake changes, etc. But the dyno sheets with other measurements (air flow, fuel flow, BSFC, water temp, oil temp, etc.) would add value.
I'm the same way about dyno numbers, that's why I'd like to at least see the sheet and/or MPH numbers at the track....and I also like to see back to back tests.......but just throwing numbers out there doesn't do much good.....I'm assuming there are motors out there that have been on that dyno with comparable numbers that have actually been raced, so it'd be interesting to find out what they run??? 
I've asked three times about the dyno sheet and haven't received any kind of reply......  just seems a little fishy.... 
If you can't handle the truth, you're living a lie.......

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.
