well just so you know ford didn't make the motorcraft carb just like chevy did not make the holley or on it now or a rochester

I do know... Motorcraft is a division of Ford. Ford made their own 2bbl carbs under the Motorcraft and "Autolite" name...

...and yes... a Holley is a Holley, and a Rochester is a Rochester...

Regardless of who made the Autolites they would seem a bit small for your needs. The Mustang had a 170 I recall. and a 240 (?)

The stock 2V carb on the 250 was 1.69" venturi according to my manual. and the jet was either .106 (250)or .128 (250-292)

I just look at my second post I sounded like an ass, sorry. Ok its just for the time that I dont have right now to rebuild the holley carb, that i was thinking on puting the ford carb on it and wanted to know of some one who might have done it already or maybe a holley 2 barrel that I have that was also on the mustang but dont remember the ventury

No worries... cuz I was being a doo-doo-head myself on my initial post.

I made the hole in the stock intake man. oval for 2 barrel carb. and machined the surface and made and adapter from aluminum and then plug the intake to exahust with hi temp cold weld I use the ford spacer then carb and now it runs better than ever, (since I got it in 2006) it was easy to do and cheap
