This is on a 1957 Ford C600 COE flat-bed truck.  I have found that 3 cylinders on my current 272 y-block have extremely low compression.  I'm thinking I should just replace the engine with something reliable, and maybe even more powerful (this thing is a dog, admittedly only running on 5 cylinders, but still).  What options do I have for a replacement engine that will bolt in to my engine bay without crazy adapters and so forth?  Also, if anyone has a source of such an engine, I'd appreciate a link.

Cheers,
Tim
