They honed the cylinders (which were already 30 over), machined the heads, did valve jobs, installed high power oil pump, new timing gears & chain, turned the crank (20/10), sized the pistons, new bearings, new cam ("one step higher than factory").
In the meantime, I picked up a Monster Transmissions 200-4R (built to 550hp and 500tq), a lock up torque converter (1800 stall), and a 3.73 (had THM400 + 3.08). Sidelining the original transmission in my garage.
Anxious to get back on the road! Very anxious to see/hear/feel the difference!
