Watch valve cover clearance
With ZZ4 heads you should be just under 400 ponies
Should run a 750 CFM carb. 650 is too small.
Be sure to have an exaust system to let it breath.
Stock exaust manifold will choke it.
Need good headers & true duals 2.5"
Need at least 3:55 rear gears too
thats the right way to get the horse rating promised and the street performance. Less aggressive gears will bog it.
Don't think I'm forgetting anything....
It also likes 36 degrees full advance around 2400 to 2600 rpm's
Get a jet kit also for the carb...forget what my power valve is. I know I changed it.
