Very nice numbers. And considering that particular dyno seems to be conservative on power numbers, this deal ought to rock!
That is for sure.
That engine will sure find any weak spots in the drivetrain.
I know the plan has been in the works for a while. Nice to see it made the numbers
Are you able to keep your stock hood?
Hey Rob(Kam Camino!)
Stock hood is Ron's goal. His tranny is built up enough with good parts,Dana is from Dr Diff, not sure about the driveshaft/U-joints. Main thing is to get a looser conv and install his Caltrac set up and i think he'
ll be going to Wallyworld on a regular basis to change his shorts!! LOL

This is the car that it's going into. Will need several upgrades to the fuel system and driveline.

Nice Ron! 
68's are the best looking Chargers (I think).
Wow, 4100 lbs, you must have the spare tire and
tool box in the trunk.  I would bet low
10,s with that much HP & TQ.
Next will be the idea spinning in your head, maybe
just a little juice to hit that 9 sec zone once.
That's if it doesn't make it on just the motor.
Have fun on the street, and buy stock in a tire
company!
Snap your neck, mega G-force launch, is all I want!

Really nice combo. With the availability of the new World blocks and the longer stroke cranks I think we'll start to see a lot more of these big inch engines hitting the street. Looks like that 337 intake worked just fine on your motor.
Did you use a double valley cover or did you make some end rails and use the floor of the 337 as the valley cover?
Andy, the 337 was the best manifold on this build for sure. Dwayne says it has the sharpest throttle response and will have the best drivability in the car. The smaller runners are most likely keeping the velocity up and the carb signal strong. It was even more responsive than the ICH dual plane according to Dwayne and made better power. I'll post those results below.
Dwayne used the ICH valley cover with the removable center underneath the cast in 337 valley plate.

I think you need to determine if the loss of oil pressure is do to lack of quanity or a oiling system problem caused by the pump or pickup before changing parts. Did you leave the .040 oil restirctor in the passage to the rockers or does the EZ heads use external oiling? If external forget the question about the restrictors and maybe consider using them in the external lines to the heads if you don't have them yet
Hi Cab,
The 295 EZ's use an external oil line system and they allready have a .060 restrictor in them. Dwayne feels it's an issue with the long stroke creating windage. He ran into similar issues with another 572 build and the dual line external setup fixed it.
We tried to go internal oiling thinking that perhaps the low rpm would keep oil pressure in check but it didn't work. It was worth a try and we learned something from this dyno thrash...Big stroke builds create lots of pressure issues that are easily resolved with a good pan and oil pickup. I'm going to order the Charlies pan and Milodon setup & be done with it.

That's correct....stock hood for now. 
Trans is fine with all the good stuff allready. Got a new locker unit for the Dana and it allready has 35 spline axles. Need a new driveshaft with 1350 u-joints etc...
Hoping to give the Green Monster a descent heads up race...should be fun. The last time we lined up all i saw was your tailights....all the way down the track !

Thanks BDS...that is the raceweight (4100) The BP weighs in at 3850 with a full tank of fuel (18 gallons) and the car is complete with full interior, heater, wipers, frame connectors and 8pt rollbar...it's a TANK !

Ok, here are some dyno numbers to chew on. Wize, Oldschool and Damon were asking for some comparative data on the ICH dual plane vs the MP337. I don't have the dyno sheets yet but here are the peak numbers. The carb is Dwayne's Mighty Demon 850 that he was trying to dial in and it ended up working pretty good on this combo. The MD 850 has downleg boosters + 86/97 jets + .026/.026 hs bleeds. The carb was kept identical for all of these tests to make the only variable the manifold & spacer combination. There are 3 manifolds being tested ; ICH 440-2/ICH dual plane opened up to max wedge/MP 337 (1) 440-2 no spacer = 713 @ 4300/711.7 @ 5800 (2) 440-2 1/2in spacer = 719.3 @ 4600/715.9 @ 5700 (3) 440DP no spacer = 702 @ 4600/684.8 @ 5700 (4) 440DP 1/2in spacer = 712.9 @ 4200/687.8 @ 5600 (5) 440DP 1in spacer = 717.2 @ 4300/697.3 @ 5700 (6) MP337 no spacer = 712.8 @ 4600/701 @ 5600 (7) MP337 1/2in spacer = 717.2 @ 4500/701.8 @ 5500 (8) MP337 1in spacer = 716.8 @ 4300/702 @ 5700 The final numbers for mine which will run the MP337/1in spacer & 1050 Quickfuel are : 721.2 TQ @ 4500 & 705.5HP @ 5600 > 694HP @ 6000 Ron

Nice carb tuning results!
Ask Dwayne what the final A/F was, from the 1st dyno sheet I see 13.2 at peak hp.
