There was a difference between the throttle bores on the V6's and V8's, but not between the "HO" and non-HO ones.

no, but the LTD's have larger injectors (52# vs 46# in the birds/stangs).. possibly meaning the throttle body is bigger.. maybe not by much, but we'll see once i have a couple of them side by side

just thought of something.. isn't the 3.8 CFI EEC-IV harness the same as the 5.0? just the harness, i know there's obviously a difference in injector size, TB size and EEC.. reason i ask, i may be buying an 85-ish (not 100% certain the door tag is correct to the car) bird with a dead 3.8, if the guy will take my offer..

if they're indeed the same, i think i just might go with my plan of dropping a 302 in it and attempt to tinker with the EEC-IV system to nail down a solid setup, before installing it in the heritage and converting this car to carb.. crossing my fingers that he accepts 350-450 for the car
