How to tell Gt40 vs Gt40p heads on explorer

  • Sponsors (?)


Read up on it a little last night. Makes sense with not wanting to make a second dash harness...wish they would have been in the same mindset with all of the different harnesses in the 87-93 cars (beating a dead horse).
 
@AeroCoupe are these the right 24lb injectors? It was from a 89 460 big block. Does it have to be the 92 and up for the model year?

The blue top indicates they are 24 lb/hr units and the connectors are EV1’s. The list I posted was just what I could find and not necessarily all inclusive.

How much do they want for them?
 
So this is must me but with used injectors you should probably have them serviced. This would be someone like Injector Doctor or the likes. Call around and see if anyone does it somewhat local to you and see what the cost is. I only say this as if these have sat static for a while then who knows how they will function.

If you choose to use them as is then at least get new o-rings, filters, and pintal caps for them.
