1987 Cutlass 500 Caddy
My good friend's "Caddy" powered Cutlass. It has a 30 over 500 (509) C.I.D. caddy, With Home ported small chamber heads, W 2.19/1.88 valves, Quadrajet, Performer intake, MT-10 cam, cast iron manifolds, turbo 400 and a 3:08 Grand National rear. This motor is hungry, and the factory fuel lines didn't cut it. Time to take it to the track!!!
Caddy 500 cid 8.2L dyno results
Took my 500 cid caddy motor to a Dyno shop and had it broken in and Dyno'd. Best run was 492hp @ 5000 RPM and 572f/lb @ 4000 RPM. The crazy thing to me is that it makes 490 f/lb @ 2500 RPM.
Torque converter vibration
Vibration in flexplate/TC causing major vibrations at high RPM in neutral and in gear.
