I have a 1969 383 with 10:1 CR, 452 heads, and a 600CFM carb. The bigger summit cam and headers.
Not counting weight..is there any performance to be had with going to a Ebrock RPM or other after market intake? From what i read the stock intake isnt all that bad.
thanks.
I was asked to contribute money to help solve the civil unrest in Egypt, but I suspect it's some sort of pyramid scheme.

Really , where did you read that ??? If you look at the dyno test fast68plymouth did on his 383 the stock intake leaves about 40HP on the table vs. the RPM , no other changes .

I dont think the stock 4 barrel intakes are too great, maybe theyre decent in comparison to an old school Offy or a crappy Weiand or something, but the RPM is a far better intake. Its been proven on the dyno and at the track. Even on a stock 383 I'd bet its worth 20 horse.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Just depends on your intentions.

I realize the benefits of an aluminum manifold but I am looking for creativity with what Ma Mopar gave us. I'm curious about how much port matching would help, also what difference would it make to mill down the plenum dividers? Are there other "tricks" such as air dams that would make a difference? I'm the type of person that likes to optimize what I have before moving on.
port matching won't do much , I had an intake wit hthe plenum divider removed , nenver tryed but it was down to knock down bottom end torque , I'm doing another one , I'll be dynoing it to see what gain it does or does not give , but don't hold your breath waiting on the results .
