Just curious if anybody has an idea what I might gain by going to a dominator on my combo. My 4150 runs great but I can’t help but wonder how much it’s holding my combo back.
511 ci
Tf 270 heads
Indy 400-2 ported
Ported 400-2 intake
11.6 to 1
2 to 2 1/8 header
265/269 .660 roller on 108lsa.

On the dyno it made 742hp/699tq with a 950hp Holley.
But was pulling 1.8in hg at 5300. The carb I’m running is Marginally bigger. I’m mostly curious if I would gain much using the 4150 intake with adapter. I am only going to do it if it’s worth 20+ hp. My proform 1050 works well and has great street manners.
It’s in a 3600 race weight cuda with a tkx 5 speed. 4.10 Dana and a 29x11.5 slick.
I made one easy pass last summer since I didn’t have a cage yet and just wanted to get a feel for the car. I went 11.26@130.5 but this spring I want easy mid 10s or lower.
I feel am 1150 would be what it will take to feed this beast. What are your thoughts?
