What's everybody running on their BBC for intake manifolds when running a Qjet? The stock cast iron manifold? Mine is a 454.

Slowpoke70 Nov 11th, 04, 2:10 AM From what I hear, the Performer RPM qjet mr 4 speed Nov 11th, 04, 6:54 AM The Peformer works just as fine as an RPM for a combo thats cammed with that less than 235 duration @ .050 in my experience Mike Feudo Nov 11th, 04, 11:30 AM I would stay away from the Performer because of the port size (they are peanut port)The RPM is an excellent manifold or there are older Q-jet manifolds around but they are hard to find. The factory sunken manifold is terrible don't use it unless you are restoring a car and must. mr 4 speed Nov 11th, 04, 11:43 AM Mike,just an FYI,I found no difference between the RPM and the Performer at the track..same MPH,same ET,same 60 ft. under various weather condtions..this was shifting at 5500-5700 m71 Nov 11th, 04, 5:20 PM i had an old performer 2-O and it was not peanut port. i would either use it or an rpm q-jet. pdq67 Nov 11th, 04, 8:20 PM Or try a Weiand 8005 intake.. It's a good one too... Should be half way between a Performer and an RPM in hp potential, imho... pdq67 | ||
