In high school I had a .060"over '59 261 motor in a '54 Chevy, and a good six cylinder buddy had a '57 .060 235 in his '57 chevy both had their stock cams.
The buddy wanted to try out my "Corvette" cam, so we swapped out cams (see what can happen with idle hands). We swapped cams and lifters. My solids went into his 235 and his hydraulics went into my 261.
The reason for this post is: BOTH CARS THEN BEGAN TO SMOKE LIKE THEY HAD RUBBER BANDS FOR RINGS!! The question is WHY??? After about a week we both were dying to swap back, and when we did both engines went back into their normal happy smokeless lives. He couldnt stand the noisey lifters and the smoke, and I couldnt stand the smoke either (but I did like the quiet hydraulics-sounded like a new car!)
Why, and what, caused these cars to smoke? They each ran fine with no big performance changes (at least none for me!). Cams were installed correctly on their correct marks, both cars were Texas cars with regular road draft tubes-of course no smog stuff.
The smoke did come out the tail pipes (both had split manifolds and dual exhaust and so all pipes did it) You could rev them up at a light and the fire trucks would come running with lights and sirens (almost)!
Any ideas-surely no one else was dumb enough to do this thing too?
