carb recommendation

[66flareside]

what 2 barrel carb would be better for a stock 352 in a f250 at 9000 ft. above sea level. a holley 500cfm or a holley 350cfm? or what has been your experience with some rebuilt motorcraft 2100?

thanks,
brad

A motorcraft 2150 with a 1.23 stamp would be best its a 354 cfm carb and works well at high altitude.

A 500 cfm is too big for your needs. It will be real sluggish on throttle response. Get the 350cfm version.

There isn't a good Autolite no matter what it is. I've never had any luck with them.
