I have a line on a Throttle body injected 460 ( I guess it is Ford's early attempt at fuel injection). The question is would this have heads like a carburated 460 or the later EFI 460? I am told it is out of a Lincoln

 

are you sure it is a 460?
never heard of a 460 with TBI on it from the factory. the only Ford TBI engine i can recall are the early 302's and 351's ( i think around 83 - 85 had them) with the TBI from the factory.

if it is out of a newer Lincoln then it is probably the 351 as they haven't put a 460 into a Lincoln since at least the late 70's at the latest. i think 76 or 77 might of been the last year for 460's in Lincoln.

if i was a betting man i would wager it is a 351.
