318 or 360 Roller Swap

the 318 should have the 302 heads and would match up with engine parts you already have better, the 360 should have the 308 heads and has alot more power potential!! but you need to sale that carb and intake and buy better for the 360! use the factory roller cam parts and lifters, get cam reground to match your combo! then get sure grip and gears under it! match up a converter..it could be a real strong runner for sure!
