My builder is charging me $500 to dyno my engine. That includes break in, setting the timing and carb (includes jetting), and the dyno pulls. I don't think there is going to be a limit to the number of pulls but if we hit our number early, I don't want to keep hammering on it, I want to get it into the bed of my truck!!
I'm sure if there's more left in your motor, the guys here will help you find it. Those numbers should be fun enough to keep you busy in an A body for a while until you sort it out. :cheers:
