hey guys I have a question? I am running a 99 mach z, port timing changed and pulling 164HP on the dyno at 8400 rpms. My secondary is stock 50/47 at 20.5lbs. My primary has adjustable pins at about 20grms pin weight and 286 ramps. I raced my sled on the ice last weekend and took first place what I was wondering is I have a set of 280 ramps sitting aside are these 280s better then the 286s for a drag race?

Both good ramps, the 280's might work better for 660ft. You won't know until you test it. I would use the 286 ramps I thing there a better overhaul ramp. But again you have to test it to know.
