Sorry but another 318 cam question.

So I bought a re-ground, long snout roller cam off ebay a couple years ago because the price was so cheap and I thought it would work ok in a 360 magnum. Well I came across a really nice 318 magnum for cheap and bought it just to get my car moving again. So I guess I just want to know how disappointing this cam may be in a otherwise stock 318 magnum motor.
Car is a 69 dart two door custom with a 904 and stock 71/4 rear with 2.70 something gears. I am looking for a 8 3/4 with 3.55 or 3.91 gears to replace the little rear(they are hard to find around here). Also will be getting a new converter was thinking 2800?
Ok so here are the cam specs. Sorry I don't remember the company's name that I bought it from but I believe they were out of Texas.

The car will only be for cruising around, no long highway trips,although I will "get on it" quite a bit . So the new rear end, gears,tourque converter, headers, etc. Are bought or will be bought. I also purchased hughes 1110 springs and retainers. I'm fairly certain they will be fine with this cam but what are your thoughts?
