I think RRR has good suggestions...keep the cam below 268-270 duration so you can stay with your stock gears/converter...
EDIT: I would however, suggest that if you're going to do a krylon rebuild that you sling on a new timing set with one of the Mancini MP Timing Chain Tensioners - $34.00 unless you know it's been R2d recently...just a thought, and just my .02
