Re: STACKED PULLEYS RESULTS! DYNO and 1/4 MILE!
Don't bother with the headers. I'd assumed with one little exhaust valve and restrictive manifolds, headers would make huge power. They don't. 4 hp is what I got from top of the line long tube headers AND the install required lots of wizardry and improvisation. I'm sure the headers would be worth it if we could raise the redline to 6800 and up.
