i have picked up a 94 block and heads and have a 88 vert in the back yard that i am gonna be doing a 5.0 swap to later. it is just basically fully assembled heads and block and nothing else. so pully's and everything is off and am gonna be ordering some udp from am since they are so cheap might as well instead of stock. so am i needing to get 87-93 parts to build up on or 94-95? not only pullies but stuff like wiring harness and stuff what should i be looking at getting

 

94-95 for all the electronics, so it matches all the sensors and what not on the block.

Not sure if you can splice in the dash to work with the 94-95 harness or if you'll have to get a speedo and everything from a 94-95 car too.

 

I think my speedo is cable and not electric so speedo should be fine don't know about the other stuff on the cluster. What year did Ford switch to serpentine belts?
