Yeah. Hey I have an edelbrock pro Flo intake on a 5.3. Im doin a swap in my older pickup truck. Also I have a FAST 90mm tb. When I went on to bolt the tb on I had alignment issues. I mean I have the top 2 bolt holes line up great the lower right doesn't mate up all the way to clear and the lower left u can't see the bolt hole PERIOD. I have the 7139 intake. My tb is for a ls1 not ls2. I called edelbrock and told them about it and the guy said send him some pics and I did n no feedback or response. Has anyone else had this problem. I thought all the tbs had the same mounting points regardless of intake u use. I see edelbrock tbs on fast intakes y not the other way around. Tried to attach pics from my smartphone to this comment but cant

O really what have you come up with? I was told to drill out the lower bolt holes. Either that or buy an edelbrock tb. This is crazy and doesn't make any sense.

i found a company that makes a adapter plate, bought it and its so far off from working its not even funny lol im going to take my intake to a buddy of mine and have him weld shut those holes and redrill/tap them in the right location

Here's what it says on the Edelbrock website about the Pro-Flo intake manifolds..
" Accepts Pro-Flo XT throttle body #3869/#38693 or adapter #2737 and standard LS1 throttle bodies."

S10junkie thats sounds like a great plan to follow. 99bluz28 u r right but here's my thing if u have an intake that has a 90mm opening for a tb and u have a 90mm tb u should b able to bolt it straight up with no problem. It doesn't make sense to me if I use A intake I have to use A tb or if I use B intake I have to use B tb. I should b able to use either or. I seen edelbrock elbows with nick Williams tbs I seen FAST intakes with holley tbs.

another option, if you dont have a welder available, i talked to my father in law that is a machinist for the government, noone really knows what he does haha he said i could find a aluminum bolt, loctite it in the hole, and file it smooth to the face of the intake, let it set up real good, then drill/tap the new hole, you could also use brass

A machinist for the govt! Sounds like top echelon assassin lol. I tried to line up my tb and the lever on my tb doesn't line up with the throttle bracket. Idk I look at it again it mite line up with the circle part for a lokar cable to go through. I will try the loctite
