340 cam

Dunno. bought this engine in the 70's, it was my wife's driver. Never saw that 30 degrees, and I had to have timed it. Dammit, I had the timing cover off, due to a leak last month- chain was tight, put it back together, not knowing about the timing. Have a degree wheel 5 ' away.
It is a cam installed in the 70's. Installing the newer trans next week; after getting drive shaft made, off the stands, and find out how it runs on the street, I guess.
