Now that i've had the car running again for about five days i've decided that i'm ready to tear it apart again. I've just about had enough of the Qjet, so i'm getting rid of it, and getting a speed Demon 750, (haven't decided between mech. and vac. secondaries yet). I figured while i'm at i might as well get rid of the Performer manifold for seomthing that breathes better at higher rpms... I've been looking at the Xcelerator, the Stealth, the Performer RPM Air gap, and the Torker II. Emissions is "kind of" an issue (if i have to put the old intake back on, it's no big deal, but it would save me some time if i didn't have to). Hood clearance shouldn't be an issue as i'll be buying a cowl hood of some sort at the same time.

Any suggestions as to which manifold would be best on my application would be greatly appreciated. Heres the setup for those who don't know:

Trick Flow aluminum heads (64cc, about 10.2:1 comp)
Crane 272H cam, 218 dur, .484" lift, 112* lb sep
Will have a Speed demon 750 carb
intake????????.

This is on a more or less stock bottom ended 355 if that matters

Thanks for any help...

I like the Stealth for $110 idle-6800 rpms, but I haven't used any of the others.

 

Air Gap. I can't remember where (I'll look) but some mag did a test and it outperformed them all. This was both peak and overall underarea.
