2 bbl. Motorcraft & a dwell cam

OK, lotsa input, thanks. Timing is @ 36 initial & 42 total. I bought a box full of these 2 barrel's off E-bay so I have some spare parts. I took all the jets to work & reamed them to between .064" & .070" but I don't know what that would convert to in a Motorcraft jet #.

G.A. - I'm curious what your 2G measures in the venturi & throttle blades.

Ed - Yes it idles best with the mixture screws closed, with the spare parts I've got I might go close up the transition slot too.

Billy - Without giving away secrets, what #'s roughly should the cam have? (or just tell the grinder 6K ?) Going smaller cam would be more palleteable than all the really stiff springs thick wall large dia. pushrod deal. But I'm almost committed to the higher RPM deal at least convertor-wise. I spent the money & got a nice one that will stall 5200 if I get my tune/gearing where it's supposed to be.

When I got the car to the track this year, the motor ran into a wall @ 5800. With what the cam company told me about the profile & the springs I have on it I figured that wall was valve float. Opinion's on if it was the carb ? It's a 1.21/1.68.
