Crate Motors
I thought about salvaging a used 360 to replace my 273 (I have yet to see a 340 in the local junkyard) but thats a lot of work. MP also now sells 340 blocks, but the crate motor made more sense to me. I did noticed that the Crate Motor I have ate a lot of oil during break in and one of the guys on another board lost his motor because he didnt check it (didnt expect that level of consumption). Others posted that they also had oil consumption issues too. I have no leaks or other issues with the motor but did find MP and Cummings less than helpful during installation.
