Also, unless you're going for a 65mm intake and egr spacer, a 65mm tb would be useless...and I think 65mm is too much for the stock fuel injectors.

The intake that I'm getting has a 70mm EGR spacer.  Would that be a problem for a 60mm or 65mm throttle body?

Stock 5.0 use the 60mm and save your money... A 65(what I use) is for modded engines(heads, cam etc.), a 70 is for highly modified engines or 347/351 etc.

If you still have a woodie for the 65 send me a PM....

Since the heads and cam won't be changing (yet) a 60mm should be fine.  I still would like to know what effect a 70mm EGR spacer would have, if any, with a 60mm throttle body.

I've never had the TPS's interchange...and those were all stock parts I tried


Hmm my stock 50mm TPS bolted riht up to a 60mm TB and worked fine. It is a factory TPS. The screws still had lock tight on them and it had never been off of the TB so :dunno:

I did the exact same thing. I have all factory units as well. I just went on autozone's site to see if the different throttle bodies had different part numbers for the TPS.

Maybe in 88 Ford started to use the same TPS for all 5.0 cars. It would make sense after all they only need 1 part instead of 2.
