Generation III External Engine - 102mm throttle body fit a pro flo?

im wondering if any one knows if a 102mm throttle body will fit a edelbrock pro flo intake manifold

it should bolt up not sure how big the opening is on a pro flow you may have to port it to get to a 102 opening

the proflo im looking in to is thels2 style so it has the edelbrock 4 bolt pattern and the standard ls2 4 bolt pattern and uses an oring seal. the 102mm tb has the ls2 bolt pattern so if some porting is needed im not against it. but i need to know how much may need to be ported or if its even possible to open it up that much.
any one have a mesurement of the pro flo opening?

Talked to edelbrock and its a 90.

Ive ran it on the dyno...... 90mm......

So any thing then a 90mm the opening on the proflo will need to be opened up?
Would it be worth it to open it up some to fit a 92, 95, or 102mm ? Looking for 1k wheel threw a th400

If your going boost I would just keep it at 90mm.

I know this thread is old but I figured I would post this in case someone ever searched this topic:

We've never been asked to port them to that size but I don't see any issue doing that. I believe most large throttle bodies stay within the factory O-ring seal. The flange has plenty of metal to grind if needed.
