They will make a very good hot rod motor,I had one in my pro street 57 Chevy,And it would fry the 18.5's at 50 mph.And that was with stock pistons .I went with the stock pistons because every where's I called they told me they had to be custom made for about $1.000.00 so I deck the block and shaved the heads,and put low cc heads.And made a very hot motor with a really nice cam.I wouldn't build the 366.
