New Cam Timing Results
Today I Installed my lunatic hydraulic roller I bought from cutlassefi. Initially lined up the cam sprocket and crank gear dot-to-dot. After finding "true" TDC, I measured for the centerline of intake lobe. Using a Cloyes 3 piece billet true roller timing set with 9-keyway crank sprocket.
CAM card says:
Centerline of intake lobe: 109*
Intake Duration: 235 @ .050
Exhaust Duration: 241* @.050
Measured Duration
Intake: 235* @ .050
Exhaust: 242.5* @ .050
Results with crank gear @ 0*
Centerline of intake lobe: 105.5*
Results with crank gear @ 4* retard
Centerline of intake lobe: 110.75*
Results with crank gear @ 2* retard
Centerline of intake lobe: 107.25*
Leaving it at 2* retard and with chain stretch, should be about 108*
It's going to be a couple months before I get this all together and fired up. I'll keep you all posted.

Then take all apart part and start body finishing and painting with the engine compartment.
As as far as HP/TQ, I'm been told with the motor specs, compression, heads and cam, I should right around 500/500+.
