Take this for what it's worth....

When MM&FF was putting together their stone pony project car, they tested a 65mm (ford racing) and 70mm TB (edelbrock/bbk) on the dyno. The mods on the car were edelbock performer Heads/cam/intake plus all the bolt-ons. I think the car was making 270-280 rwhp at the time. Anyways, they claim that the dyno runs between the 2 TBs were identical, and you could lay one graph on top of the other and not notice a single difference.
IMO, go with the 65mm.
