Hi - New to the forum here and am looking for some ideas of what my 460 might have as far as compression ratio or hp. I inherited the car and don't really have any specs on it.

Here is what I know.
Block is a D9TE-AB - I know this is a truck block from 79 on up.
Heads are D0VE-C - I know these are 75 cc
Intake manifold has no name but is a similar to a Weiand Stealth
NOTE - The intake runners and intake ports have been been epoxied. See pics
Holley 850 dp.
Unknown cam w/roller lifters/rockers. Rockers are 1.73 intake - 1.65 exhaust.
Idles rough with low vacuum of around 6 to 7inches at 950 rpm. No intake leaks.
Duraspark distributor that has been recurved - all in at 2500 rpm. Has a MSD 6A
Pistons are dished. See pic from endoscope.
Compression test - 215 to 219 psi on the cylinders.
Hooker 6115 long tube headers.
Has a C6 trans with shift kit. Suppose to have 2800 stahl converter.

Any ball park guesses are welcome.

Epoxy in intake runner. Intake is upside down.
