Just bought a smoke machine.

I think those years and numbers are about right, as I bought a '95 (?) EFI 460 about a year before I bought the truck (to put it in my '68 F250), and it's sitting on my engine stand:

And if it turns out I do have a cracked manifold (in the '92) I'm kinda hoping and praying that I have the part(s) to fix it on-hand.

There was an head change in the EFI Motors I think in 94'. The last EFI head casting is the best for performance. Casting number should be F4TE. I parted out a 94' 7.5L and a guy is Michigan and he sent me crates to ship him the heads to him.

There is a guy who sells an adapter to use the bottom of the EFI intake with a carb.

If it has an oil cooler, those are known to leak internally. Just a FYI.
