P60 vs A4
I will probably be banned from this list, but IMHO the Palmer is a far superior engine. It has three main bearings and a much better cooling system. Virtually all parts, except the crankshaft and manifolds are from the International Farmall Cub tractor engine. So, internal engine parts are easy to find and much less costly than the A4 parts.
I intend to build the Atkins Rescue Minor, which was designed for a Graymarine Sea Scout 90 CID, but I intend to use the Palmer I have rather than the A4.
