273 for 318 swap advice

I have a FREE 318, and the Schumacher mounts I have are 273/318 only. the 340/360 one's are different. Trying to go cheap. Maybe advice on more power in the 273 would be better, since it's only got about 3000 on the rebuild.

Ignition curve???

Cam timing???

Convertor?

More gear will definitely help.
