That wasn't even 5000rpm yet. The math says 4500rpm right about where the 340 cam begins to come alive, snuggled into about a 6/1Dcr 318 . That was my all-time worst combo. I was about 25, and dumb as a brick. But hey,I had just found me a wife in 77, and the plumbing was working. I had my first baby, a daughter in 1980. So there's proof right there, that even a DA kid ......................... can find someone to love.
