I know I'm probably replowing an already covered topic so I'll make it short. I bought a Performer intake and a BBK 65mm TB. The TB opening on the intake is, I believe, 65mm? My car has only full exhaust, gears, pullies . . . This is the first "engine" bolt on that I have done. Shoud I have gone with a 70mm or will this 65 work OK? I'm not losing sleep over it - just curious. Thanks in advance.
65mm TB work OK w/ Performer intake?

Your fine. Don't lose any sleep, go back to bed 
I wish I could.
You can upgrade the TB down the road with a larger one once you put better heads and a nice cam in if you want.
The tb opening on that manifold is 70mm, but thats nothing a dremel can't fix.

Howdy.....I have the same configuration, runs very well.....in fact a little too much low end torque . I believe that 5.0 Mustangs did H/C/I swap a while back ("Stone Pony") and when they tested a 70mm against 65 mm it was exactly the same torque/hp curve. And oh, I believe that they used the Edelbrock Performer heads/Performer 5.0 intake/Performer Cam (E303)...so I guess you are good. 
eh?

like mike said, that 65 will work good, but since you MIGHT do mods later down the road, try the 70 now.
