I hope this doesn't come across as being a smart azz as it's not my intention. But on a engine that runs 11.50's I'm not going to run a big single plane intake. My stock stroke 340 on pump 93, 4.30 gears and a hydraulic cam ran 11.60 with a Weiand X-Cellerator. Not a big single plane by any means but a very good intake that gets over looked many times.
I'm gonna be running that same Hughes cam in my 408 with indy w-2 heads and 360-1 Single plane intake. 850 carb 4-10 gear. 11-1comp. I was hoping for at least mid to low 11s. Sounds promising
