I found when I did my vortec head and cam swap I needed a considerable amount of timing. I ended up modifying a lt1 cop car timing table. I just polished of WOT on the dyno last week. Its a nice smooth curve up to 4700 rpm where Kpa starts to drop and the dyno showed serging up to 5800. with mine I zero'd out my PE timing and just use the open throttle SA table. at 2400 WOT I'm at 29* and 33* up to 6000.

I was quite disappointed with my dyno results considering how much I have put in this truck, but I'm happy with the performance of the truck.


It always seems a dyno disappoints. We read everything and calculate Flywheel hp. Then do a dyno run and get RWHP. Even when you add back for drive train loss, its never the same. It always feels like your trying to inflate your numbers. Sounds stupid, but that's the way it makes me feel.
