the new 300 has a lot more polution control crap. It also has a different set of exhaust manifolds. I think the head is also different... i believe it's got higher compression.

There's no provision for a mechanical fuel pump on the EFI blocks. The belts and pulleys are different, I'm pretty sure the water pumps rotate in different directions too.
