Easiest/Cheapest way to a 4bbl 318?

Ok, so based on information I have gathered so far, here is the new plan. I welcome comments and suggestions because I am somewhat close to clueless:

Edelbrock Performer intake (or maybe a Weiand Action Plus), Holley 670 carb, a set of "302" heads that will be gasket matched, Summit G9040 1-5/8" headers and dual exhaust, and assuming I have a 8-1/4" rearend I'll go with the sure grip carrier and probably go ahead and change the rear gears. I was also looking at the Comp XE268H (20-223-3) camshaft with 224/230 dur @ .050 and 0.477/0.48 lift.

Assuming this is what I go with, does anyone see any major problems with this combo? I know the carb might be slightly too large, but I already have it, so I'm going to take my chances.

Any suggestions on the rear gear?

I do not plan on doing anything to the block/pistons/etc or the trans/TC in the near future...is that ok with this combo? My thinking was that if the XE268H cam works ok for now, then I can get a 2,000-2,500 stall TC later and it will still be a decent cam.

I look forward to hearing your opinions/ideas.
