Default Which carbs do I want for 2x4 MR?
I have pinged a couple of you offline but I want to open this up for broader feedback. I recently found a practially new original Ford 2x4 MR intake. At some point later, not sure when, I might like to run it (in lieu of the Sidewinder/750 Demon I am running now.)

My engine is not a wild setup, 1966 side oiler, stock MR heads, Comp 294S flat tappet (248/248, .605 lift) 9.8:1 compression. It would seem to me the original 700+ cfms would be too much for street and a some weekends at the track. I have read a lot here about people trying to decide between 390s, 450s and 600s, but no one ever seems to come back and actually post how they are doing months later. If anyone can comment on your experiences and what cfm/list #s you'd recommend I would appreciate it.

Jim
