almost stock 318, looking for a little more

got my 1974 Scamp a few weeks ago, see http://www.forabodiesonly.com/mopar/showthread.php?t=141569

I wasn't going to play with the 318 since im looking to build a 360 stroker during the next winter and hopefully get it ready for next summer, but I can't help it, this car is so fun to drive I'd like to add more power before the end of this summer.

This car is completely stock aside from 1 5/8 ceramic coated header and dual 2 1/2 exhaust. Automatic 904, 8.25 rear end with whatever gear.

Would I be wasting my money if I was to add thing like a new 4bbl carburator, intake and a mild cam?

Suggestion?

Currently only a weekdend driver, no strip.
