Before i got my engine rebuilt, i switched from 10w30 to 20w50 oil. The heavier stuff made the oil pressure rise a little bit, and it didn't smoke quite as much. You could drain out the oil that is in it now and put in some heavier stuff, but that would be a waste of $10 or so....

My Daily-Driver: '72 Chevy LWB Custom/10. Rebuilt 350, 300 HP thanks to a few go-fast goodies. Ochre with a white top. Future plans include a frame off restoration, and maybe a blown 383.
