Good to meet you guys. My son and I are looking at buying a 73 challenger project that comes with a "Mopar Crate Motor". I am trying to verify the engine specs and am having trouble finding a place to help. Attached (hopefully) are a couple pics. of the engine and numbers I can find on the front drivers side of the engine. I was told this is a 375hp 360.

 

For anyone else that may be trying to I.D. a chrysler engine. I got in touch with the Mopar Performance guys on the phone and they were great in helping me figure out what I have and the history around it. Turned out to be a 380hp 360 new not reman. engine from early production (has a mechanical fuel pump boss) still in the factory blue crate. Casting number on the heads 5301. According to these guys Chrysler had a surplus of these engines and the performance group started buying them and repainting them orange over the black. Later fater the Chrysler stock was depleated they were buying salvege engines out of the salvage yards and rebuilding them with new internals except the block and crank. This was discontinued due to the poor quality of the salvage motors. All the engines today are aftermarket everything evidence as to the high prices.

 

That is some great info. Thanks for sharing. Sorry we couldn't have been more help.

 

can you tell me how you found the number to talk to them. I have a stamp number and cas number and cant find any thing about it.
