help with smoke
I bought a early 80’s chev 350 out of a ¾ ton van, to have rebuilt and dropped in my k10. I had the crank turned, block 30 over w/flat tops & Hasting rings, mild cam, new lifts & push rods. Total overhaul on heads, with larger intake valves and guides. New Performer intake toped with a used edelbrock 600 that I had rebuilt, and a new Mallory hei dist. Now for the problem….it smokes and burns oil and its well past its brake in. Is it possible that my pcv valve could be pulling oil into the carb? the pcv is new and I know my edelbrock valve covers have baffles. The spark plugs also look fine and the motor runs great.

Check for wrong spec PCV also check for oil leaking into intake runners from the bottom side. Common problem if heads/block have been milled excessively. Sometimes leaving the end seals out (use silicone) and using thicker intake gaskets will cure the problem.

thx for the tip bud, so PCV vales do have specs..? i just picked one off the shelf at discount that fit in the valve cover. i know the Machinist only shaved a little off the heads to freshen them up, ill look into it anyway. thx alot
