Re: Timing
I too am at 27* at the top of high cams and went up as high as 28.5* with very little power gained. So I backed it back down to 27 and will stay here until I get my PCD's and aftermarket j-pipe installed. Then I'll see about peeling back another .5* to 1* of timing afterwards. No knock was ever seen even at 28.5* btw...
