James:
If you are set on going the 2.7 route than how about Jim R's suggestion and pick up some JE's, a set of webbers, cams and going for 200+ horsepower?
I have also "helped" a guy redo a 2.7 where he didn't split the case (updates were already done + he simply inspected and re-ringed) and he converted intake side to webbers (associated fuel pump, FPR, etc...) with new cams (NOT ideal for the CIS piston but sure sounded great popping and spitting...). Of course...that depends on whether you think you can get a good set of webbers (or PMOs if you are Midas) in the $1,200-1,500 range.
BTW: I love threads like this where we can suggest ways to spend someone elses $
