Not sure about lifters. Can't hurt. I think pushrods are recommended with the cam upgrade. Mine were done with my cam.

You got a 3,000 stall converter to go with this? All that duration and lift puts the power above 4,000 rpms.

I'm good with the way it runs. I told the guy I wanted it built to run on the highway. This sucker pulls HARD!! It wants to run!

Had it to the track for some quarter mile passes?

Not yet. I'm not sure if I will tho. It's my gf's daily driver and we can't afford to break anything. I wonder if the sticky track would break something, because it's so sticky.

You can always launch from an idle so as not to put maximum strain on it, what you're after is the trap speed. That and a trip to the scales will give you your actual rear wheel horsepower.

Lifters and valve seals while your in there. U don't want one with that many miles collapsing on ya. Definitely do hardened pushrods.

Probably should do lifters with that many miles, agreed, along with hardened pushrods and dual valve springs and quality vitron valve seals. Unfortunately you have to pull the heads to do lifters, otherwise you can do everything else without pulling them.

Definitely do lifters. I did not change the lifters in my Firebird and one of them broke a roller a couple of years later, which also took out the cam.
