Does anyone know if this intake Holley Pro-Jection Intake Manifolds: HLY-300-49 - summitracing.com
will work with out stock rochester tbi?s

I was looking for a good price on a Performer 3701 w/ egr or a Weiand Action+plus w/egr 8000 and found this. I think I saw someone asking about the projection in another thread but I can't find it.

So what would be best? The performer 3701 the weiand 8000 or this Holly 300-49 (if it fits)

 

The Holley Pro-jection manifold is meant to work with their TBI unit. It will move the GM unit forward and force you to do some modifying to get your cables and pipes to reach.

I'd go with the Weiand ...should give you a bit more top-end potential than the Performer (and you won't loose any bottom end).

Honestly, I wouldn't go with either one. TBI can handle a bigger plenum than either one of those manifolds has. A Performer RPM style is nice, and a lot of people like single plane manifolds for TBI. ...but if you're sticking with a mostly stock set-up, then the Weiand and Performer will be more than adequate.
