I agree that 750 is a little much for a 318 and a 600 is good enough....
Those are decent numbers for a street engine... Nothing wrong with that... :thumbsup:
I have a similar engine going together right now...
72 318 standard bore with 8.5 compression, 67 closed chamber heads ported with 1.88"/1.60" 360 valves, Edelbrock LD4B intake, and a Holley 600 vacuum secondary with electric choke.... Can't remember the cam size, but close to yours...
I plan on putting it in my 66 Valiant wagon for street cruising... :steering:
