ANOTHER small block question(318)

So, I think I'm just going to stay with the slant in my Valiant for right now and work on a 318 on the side since those are pretty cheap here. What do you guys think a 318 with 340 heads, intake, and this cam

would make, hp and torque wise? My logic for choosing the 318 is 1) they're common, and 2) a hell of a lot cheaper than local 360s. I already have most of the parts laying around. I'm not looking for a super high output special deal here, just something to have fun with. I think it's better to get my feet wet with engine building with something cheap and common rather than with a $500 engine core. Also, any recommendations for books on SBM engine building? I have a couple chilton manuals, but I hardly believe that's enough of a reference to build a V8.

I do have a repair manual for the / 6 though.

Thanks all,

Josh
