Here is what I think I know...there are three versions of the Motorcraft 2 bbl. The 2100, 2150, 2700. I currently have the 2100. I am looking for possibly a little more CFM than what the 2100 currently puts out, but I don't want to lose the extreme angles that I can currently run at with my 2100. Is it even worth trying to put on the 2150 or 2700, or am I just wasting my time. I am just trying to add a little power potential without losing the off-road capibility of the carb. Also does any one know the relative specks of the carbs as far as CFM.

From what I hear:
2100 = 300CFM ?
2150 = 400-450CFM ?
2700 = ?

It will be going on a 360 with a stock 2 barrel intake.

I dont know the answer to any of your questions but i do know that there is a few people over on theparts mike (www.partsmike.com) board that are 2100 masters.. you might try there.

I believe there are different size bores for the 2100 also. Therefore a couple different CFMs, not just one.

Check TMartin's reply on page two.
The 2100s have a number cast into the side of the float bowl. This determines the venturi size, and CFM. A 2100 will fit your needs.
