Thanks Dave! It runs real strong. Merc crank, Ross pistons, 97s have .43 jets, .79 power valves. 39 trans with LZ gears, 40 rear end with 3.54s. 3000 RPM at 65 MPH. Mallory dual point. The 3.54s are not too tall in a light car like this, I can drive it all day on the freeway with no problems. The 40 rear has 9" Ford axles and brakes. No worries about broken axles!
