Engine Mechanical problem
1972 Chevy Truck V8 Two Wheel Drive

I just got done adjusting my valves and i got some popping sounds coming thru the exhaust,was wondering if it might be the valve adjustment or maybe the timing,i just put a new cam in and had the heads gone thru,also put a gear drive timing set in.sbc 305

It sounds like your valves might be too tight, loosen them about a quarter turn at a time each until the popping goes away. Is your geardrive the adjustable kind. If it is you will need to set it at 0 degrees and make sure your timing marks are lined up. I would do the valve adjustment 1st, its a lot easier. Check your firing order and timing too.
