I AM GUESSING THIS ENGINE IS OUT OF A 69 TEMPEST. THE BACK BLOCK CASTING IS 9793079? COULD BE 9790879? THE 4TH AND 5TH # IS A BLUR. THE NUMBER ON TOP OF MOTOR ABOVE FLYWHEEL IS K077. THE FRONT OF ENGINE IS 9790347? THE 3 COULD BE AN 8. ANOTHER NUMBER UP FRONT IS 237019 YN.
THE HP QUESTION. I HAVE A 4 BARREL INTAKE W/600 CFM HOLLEY. I HAVE #17 HEADS. ENGINE IS BORED 30 OVER. IF THE ENGINE IS A 69 TEMPEST MAKING 265 HP STOCK WITH 2BBL WITH 9.2:1 WHAT KIND OF HP COULD I EXPECT.
