im currently running a perf rpm in a 68b-body(3800lbs) 451low deck eddy heads comp XR286 solid roller holley ootb 850.car runs real good 11.12@120 through the tailpipes,air cleaner,no real tunning.im sure i can squeek 10.99 when the good air comes around or if i open the ex but i like to run in full street trim.was just curious if a single plane intake might work better?i know the car is heavy and im limited for hood clearance and intake choices but i have a line on a torker 383 cheap and was wondering if it would be worth trying?has anyone track tested this?ive read some dyno articles on intake comparisons but id like real track input.
