My 440 Build. Which intake and WHY ?
Below are two Hotrod Magazine dyno test results on a mild build 383 that I recently found comparing the Edelbrock Performer to the Performer RPM intake manifold. Although I have a 440 and not a 383, I think the info is relevant for comparison purposes.
I am currently trying to decide which will work best for my build and for how I use my car. I would like to get a few more opinions on which Performer intake and why. I am not going to be making any additional performance upgrades to the engine in the future. I drive the car weekly, enter local shows, cruise-ins, occasional A to B locally, no track plans. I have a lot of people recommending the RPM but they can't tell me why it's the one for my build other than it "breathes better" on their 10 second, 600 hp track car and "won't run out of air above 5,500 RPM".... lol, OK but did you listen to what my build and use is? I am looking for low end street performance, great throttle response, pin you back in your seat stuff. I doubt the motor will spend much time up near 5,500 RPM and probably no time above that with my cam, gears and the rest of the build. Also I have enough room to close my hood with either intake.
My build is the following:
I have a 1975 Chrysler 440 V8 in my 1972 Duster.
MOPAR purple cam #P4529270A
268/284 degrees
Duration at .050 inch lift is 228 int./241 exh.
Lift: .450/.458
Edelbrock E-Street Performer heads (75cc combustion chamber so CR about 9.3)
Edelbrock 800 cfm Performer carburetor
TTI long tube headers
323 gears with Sure Grip (posi)
727 Torqueflite with stock stall and B&M shift kit
Mopar electronic pointless ignition (Orange box).
