Performer vs. Air Gap

[Fat Daddy]

Told the Air Gap would be better on my +.030, 4.15 stroke, Eddie heads, 440. I see lots of opinions on the net both ways. Seems a lot lean toward both performing close to the same.
Went over all the - heat the AF mix, need a heat shield, block off the riser, good low end torque vs. high end rev, blah, blah, blah.
Lots of Chevy and Ford articles but couldn't really find any Mopar articles.
Any thoughts would be appreciated.

Do you mean Performer vs. Performer RPM? Because all 440 intakes have an 'air gap' by factory design...yeah edelbrock 'borrowed' the idea for other engines from the big-block mopar! In any case with a stroked big block and aluminum heads I would definitely go with the RPM intake... in my opinion the best dual plane out there

I'm running a performer RPM intake on my 4.15 440.with RPM Heads. great manifold.If your street driving it's a good choice your motor should make lots of torque

Edelbrock heads have no heat crossover.

The Performer RPM is the tallest of the bunch. Hood clearance is an issue without a drop air cleaner.

The Performer is more of an aluminum stock design. It's a little better than stock but not a barnstormer. The RPM is a performance dual plane. It's a bit different design and much better. Probably one of the all-time best and well balanced for low and high rpm work. I would not use the Performer unless you were building a basically stock engine and were missing the intake. The RPM is really that good.

What will you use this for? I was able to use a Victor single plane on my Satellite (4.15 440 & EDE RPM heads) & still be very streetable (hood clearance issues though). But it had a 4.10 Dana & 10" Turbo Action converter. A friend used the RPM dual plane with good success. As the others have said, all big block Mopars are "air gap" & the EDE RPM heads don't have a heat crossover to block off.

Sorry. Should have specified Performer (not Performer RPM) vs. Air Gap.
Thanks for all the feedback.

All big block MoPar intakes are "Air Gap" intakes since day one.

Your interested in the performance difference between the "Performer" and the "Performer RPM" intakes.
Take "Air Gap" out of it all.

IMO, Moper nailed it in his response.
