87 into a 92

[byoung22]

I just picked up a complete 87 5.0 to install into my 92 GT. What do I need to do to keep the set up mass air? Can I just swap the t/b, or do I need to use my engine harness from the 92 as well? Thanks for your help!!

You definitely need to swap throttle body but I think you will need your 92 wiring harness for the charcoal canister. The 92 engine wiring harness has the canister wiring while the 87 had every thing on the fenderwell. That all I can think of.

Can I leave the 87 upper and lower (intake) on the engine? The one from the 92 are pretty ratty.

Nothing on the engine dictates mass air or not. Swap the entire engine, pick the parts you want. If you want mass air, then just use all the same wiring and slap the meter on the 87 engine and there you go.

Use all your 1992 wiring and just swap the engine. Keep it simple, no need to think any deeper than that
