Default HP estimates

5.3 LM7 block
Stock crank, rods and pistons
799 heads milled .017
Brian Tooley Racing .610 lift springs
228r cam
LS6 intake

Bottom end just got new bearings and ball honed cylinders so everything has been freshened.

Just curious what HP I ca. Expect when I am done or what budget friendly changes I could make before I'm done. Drivetrain is TH400 with stock stall (for now) and 3.08 posi gears.
