Cams for 318's
Mopar performance Cam durations at .008 tappet are all listed in the old Direct-Connnection catalog, and in the later Mopar Performance catalog as well.
Not in my wildest dreams would I install a 114*LSA cam in a normally aspirated street SBM. I know many guys like that 340 cam, but I wouldn't pay a nickle for it. It was designed to run in a 340 with log manifolds, and it did a pretty good job of it,...... back then.
But everybody in hi-school who had one of those 340 cars, one of the first things they did was pitch that 114LSA cam and install headers. Which promptly turned a mid-14 car into a low-13/ hi-12 second car; Just like that.
Well everybody except me, lol. I reasoned that my 340 car had serious traction issues, and I needed to address that first. So that is the direction I took mine. In three years, anywhere but at the track, almost no one could catch my stocker, lol, and boy were they pissed.
