    Bought a Lincoln LS throttle body I am going to try and adapt to the Merc. Near as I can tell, it’s a 70mm unit I pulled off a 3.9L V8 engine. Big concern I can think of will be intake tube, as I am pretty sure I can machine it the way I want.

    Here's a CVN link that might be worth consulting [edit: I subsequently noticed that you had recently made a post in it]:

    Gave in to a whim and spent $20 at walmart for the tools I need for the throttle body. I may modify more of them for other Panther owners if the results are satisfactory, so I consider the costs well spent. Going on this weekend.

    Installed the throttle body today. Had to get an adaptor for the P71 zip tube, opening was too large. Recommend going to a CAI style pipe to the air box if someone did that upgrade.

    I know for my 2000 MGM, a 2004 CVPI zip tube is both too short and too big at the air box end. Apparently some people cut off the air box end of the original zip tube and clamp the CVPI zip tube over it, though that's not something I'd bother doing. What did you use for an adapter?

    Got a 4” to 3” intake coupler. Had a 4” to 3.5” ring I used on the 4” end

    Odd, when I put the BBK 75mm tb on my '05, the zip tube fit perfect(both the Sport and CVPI). But I do know when others put the Ford 75mm on, the zip tube needed to be enlarged.

    Looks good. May need some longer bolts though.

    So the bolt pattern is off, same as the 75mm Ford TB. I'd be concerned with the rubber coupler clamped around a hollow plastic tube in the long term though.

    Yeah, I am too. Will be swapping metal piping eventually, once I have a little cash for it

    Yeah. That one is shorter than the rest, I accidentally dropped one in a storm drain. Used the LS bolt instead. I will note that the throttle body has to be mounted upside down, but it works fine that was. Using the LS throttle position sensor and motor though because of it

    At least the 'plug-and-play' nature of it makes up for the hassle of messing around with the bolt holes. How well do the bores match between the TB and plenum?

    The plenum and throttle body match up almost exactly. Was not expected, thought LS would be bigger since it appears the throttle body may have been the basis of the 75mm as well. Took 20 minutes to do it all at least

    That actually makes sense to me. The plenums never really changed much other than them not drilling thru the IAC ports, and its well known that the older plenums are 70mm inside diameter. Why all '96+ plenums are 70mm but all '96+ throttle bodies are 65mm, IDK.
