the 337 must be better than it looks.

That's what Dwayne said. The runner volume on the DP is larger so it wasn't as responsive to throttle position change as the 337 was. It's one of those things that might not show up on the dyno but would be noticable in the car....especially a 4100lb Tank.

I'm anxious to see those sheets as well !

What air filter are you planning to use? The lack of a fresh air hood on a Charger limits you somewhat-but the looks are certainly worth the tradeoff. I would think it gets a bit cozy-even with the relatively low rise manifold...

Just curious ....

Hi Mike, right now i've got the K&N 14x3 1.25in drop base assembly with a flo-thru top. Old School is running the same manifold/aircleaner on his 580 engine with a 1/2in spacer and it clears the factory hood on his 70 Charger.

I lowered the K-frame on mine 1in with spacers (thanks for the idea Big Squeeze) and will use the 1in open spacer. The 337 is pretty low....almost the same as the Holley Street dominator that's on the 446 currently. The raised Indy intake ports will tighten things up but it will still clear....i've measured.

I agree...the scalloped stock hood looks best without a scoop.

Thanks Brian...just wondering if your car has a 2 speed wiper motor ? Mine does and it sticks out from the firewall....might not clear a 16in air cleaner assembly ?

Here's a pic of my current setup

Wow ron you are going to have to change the name of your car to The super black pig Sorry i missed you at MMW. So what are you going to do with the old 440 engine that the 572 is replacing?? . Mopar65

---

Hi Bobby...we missed ya at Monster Mopar !

I'm thinking about dropping the 440 into my 70 r/t and installing a stick. No plans to race that car but i'd like to have some fun and have never owned a 4spd Musclecar.

That's what i figured Brian...the 2 spd wiper motor is close to the 14in diameter air cleaner assembly. Not sure if the 16in unit would clear...the extra 2 inches of diameter could be a problem. The big 6-pack air cleaners require a 3 spd wiper motor.

Yep, that's my 70....originally a plum crazy car with white interior/white vynil top and white butt stripe & V21 hood blackout treatment. Car is now Red with black interior changed over by previous owner. It's loaded with PS, PB, PW, Cruise control etc...I'm gonna keep it red and install the butt stripe and have the hood blacked out. I have some torque thrust D's and BFG's for it as well. Check out the photochop...looks good with the steelies but i think the TT D's would look nicer.

Thanks for the wiper motor info !

The '337 intake using the MD 850 with or without the spacer will show me what I'm looking for.

Here ya go Brad....MD 850 on the 337 manifold

Looks like a nice 500in MW head intake manifold.

I'd also like to see the printout of the 2D dual plane, especially interested in the "under the curve" torque.

Here ya go Bobby. It did well but not as good as the 337

Is Dwayne going to provide you w/ any more dyno sheets? I'd be interested in seeing how the air/fuel curve looks w/ the QF 1050 carb after his final adjustments.

Here ya go Brad...best run with warmed up oil


Ron

Thanks for the additional info.

You're welcome Brad....hope it helps

A couple more for Bobby ; first up the ICH DP with 1/2in open spacer

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!

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 !
