Trying to decide on which intake to run on my 350. Performer RPM or the Holley Contender/Street Dominator 300-36

I put a new 350 small block together for my 4 speed Malibu. I have everything else hashed out already. Mild build with fresh .020 over flat tops, aftermarket Skip White 200cc heads with 64cc chambers, hydraulic roller 224 in/232 ex @.050 and I have a brand new Holley Brawler 650 double pumper. I know both intakes are probably very close in performance. The Holley is pretty cool as it is a very good clone of the original GM high rise intake used on the 67-72 Z28's. The Edelbrock intake already gets a negative for the stupid location of the vacuum port on the #8 intake runner which puts it under the rear float bowl.
I'm just curious to hear some thoughts/opinions.

I love my Street Dominator and have for 25 years. Not sure how they compare side to side but my Holley will pull to 7500rpm shifts.

Edelbrock's have always worked well for me in BBC's and SBC's and I am currently running a similar set up as you in my 86' Regal with an Air Gap intake and a 670 carb.

I'd say the Holley. I've used/will be using Edelbrocks but with the performance the Z28/LT1 intakes had it would make the copy the better choice.

Pick which one fits better. You’ll never notice the difference in performance.

RPM is the best dual plain I've run. Use the one that fits and gives the best clearances for what you are doing.

I ran a street dominator on my 6.6L 400 in my 78 Trans Am.

I WILL be getting another one, should the 305 go t*ts up and I drop a 6.6L 400 in my GP.

I have a Performer RPM in my 81. The only thing I have to say is I dont have the hood back on the car yet and it looks like its going to be VERY close as far as the air filter. Im using a flat hood.
The Holley is a great manifold. I had the early version on a 355 is my 72 Nova. No complaints at all.
