Never had a 360 but I would build one yes. I have a spare set of J heads I need a bottom end for. I honestly like the heads. The larger ports and valves. I cant see grinding and working 318 heads to try and make them flow. Aftermarket heads are nice but still a sub 4 inch bore in a 318 . Etc. For the record I don't dislike 318s I just wouldn't recreate the wheel trying to make one perform. Although I can see the challenge there. But to me it would be throwing good money after bad. I came up the usual way had a 318 first learned about 340 then found one or two LOL! I actually am fond of the 273 also. I can respect what Chrysler did with the Commando 273 in the 60s and really I consider that the initial basis for the 340... the engineers started on the 340 idea from the 273 performance engine not the 318. But that little 273 in a 64-66 Dart or Barracuda alot of fun.
