[QUOTE="oldmodman, post: 14227089, member: 10303"] I would like to say I was going to suggest that you check the compatibility of the throttle body but I had completely forgotten about this ever being a problem. I was going to suggest that you do exactly what you already did. Pull the IAC and see if the TB would then return to the mechanical idle stop and idle correctly. Only after you found the difference in the ISC transfer slots did I remember a big discussion about it on Mod Fords from like six years ago. And that one centered on a problem someone was having due to using a factory gasket with one of Doug's (Billetflow) TBs. nobody realized that the new TB and manifold had a different shape and position transfer slot. Great that you did find the problem and I hope that the new engine performs up to it's design now. You sure covered all bases in the rebuild. And going to the long tubes will really free up a few more horsepower. And with that 2.9 the engine really need the long tube to breathe. With that 2.9 you should be easily into the 700's:thumbsup: [/QUOTE]
