First the motor mount location will be off from V6 to V8, Everything will fit, Just have to take the one out of the truck the V8 came out of. Next where you may run into a problem is with the computer, Would be no problem cause you take the one out for the 5.7L with the wiring harness, and install into what you are putting the 5.7L into. But this is an OBD1 computer set for an automatic. You would have to find somewhere to get it reprogrammed for the standard trany.
