Re: Dyno Run/ Turd Alert

First the car on the dyno on a few pulls, around 5300 rpm it picked up instantly about 50-60 hp/lbs of torque. If the rockers are too tight, I dont see it picking up a ton of power out of nowhere like that, well go thru the rockers again though.

These are Comp 850-16 lifters OEM valved, need around .050-.060" preload. on a 7/16 stud (I think its 7/16-20 thread pitch correct?) one turn should be about .050" then.
