Stock heads/rotating assembly, hot cam/vlave springs- how far can you go?

You could try milling the plenum divider out of the MP dual plane and putting a one in spacer under the carb first, but it's still not going to match the RPM. Edelbrock really did put a lot of R&D into the small block Chrysler RPM intake, it's pretty safe to say it's the best dual plane ever made for the A type engine. With 4.10 gears, I myself would look for a good LA single plane and convert it to the Magnum heads and block the exhaust crossover. The top contenders for the street would be Weiand 7545 Xcellerator or Edelbrock Torker II (Too bad Holley didn't make a Street Dominator with 340/360 sized ports).

I would not bother cutting the divider down on the MP dual plane. Waste of time IMO. I also would not recommend a single plane for the street most of the time but even more so with his 2600 stall converter. The RPM can make an honest 500 ratio plus HP, out torque and match the HP of any single plane intake in a street performance arena.

Keeping in mind his 2600 stall converter and not spending his money on a new one for a good savings, I’d recommend a smaller cam than the MP 230@050 for sure. I’d recommend a cam of 224@050. This one below performs very well in my ride.

If he wants to purchase a new torque converter, then the next can of worms is opened!
