Stock intake vs Edelbrock Performer RPM - pictures
 
I thought the Performer was going to be much higher, but the freaking giant Holley adaptor is what is going to kill me.

Just incase you were curious as to how the Performer RPM compares in size to the stocker.

When you measured the clearances, how much did you have to work with? I'm planning on doing the same kinda swap and was wondering if I should go Performer RPM w/EGR (carb) + adapter or Performer TBI RPM w/adapter. If it still manages to fit let us know!

I installed a Vortec performer RPM yesterday. I have about .375" clearance to the highest point of the breather to the hood. I used a .375" tall adapter plate. I also have a 1" taller breather top installed with a stock bottomed breather. You might fit that setup with a stock height breather.

hello all, i've been hanging out for a while but I just got my login stuff straight. Will a regular (carbed) manifold work ok with the TBI adapter? I got a RPM Air gap in my shed but it for a carb and my current vehicle (1989 Trans Am TBI 305/700r4). I'm just curious if it would work ok? Thanks

Yeah but notice how much higher the runners sit on the Edelbrock compared to the stock unit.

You can get you adaptor milled down thinner at a machine shop if it's too tall, and what monkey have you been letting take off your wheels? That center cap in the last picture sure is dinged up bad!!!!

what kind of air filters are you people using (dont have one on there right now)? I donno about you but i had to do some ghetto riggin' to get all my stuff to bolt up to the edel. intake. I had to move my brake booster hose to where the vacuum port for the climate climate control is and my coil sits closer to the tb then it did before.

The way the adaptor is the bores go from 2" and taper in twards the square bore, if I got it milled then I'd have a lip from the intake manfold before the air/fuel got into the manifold.

Nothing wrong with the center cap, just funky lightin in the picture.
