Carb. for 351 Cleveland

[Brendan]

I have a 351 Cleveland powered late '71 build Mach 1. The 2bbl. carb is nearly done; I can have it rebuilt, but I want to go with the Edlebrock Manifold that allows me to put on a 4bbl. carb. I've had my 'hot rod' mechanic say that a Holley 750 double-pumper is the only way to go; the guys at the performance shop say a 670 Holley Vac. Sec. is plenty. The car is a daily driver with some highway done each day; pleasure only during the summer as I am a teacher with summers off. Car is and will remain a daily driver - no pedal to the metal; no quarter mile times required, but I do like the feeling of power that the 2bbl. is not delivering.
Suggestions welcome!
Thank you.

I'd go with the 670 vac. carb...better performance and you'll get better mileage than with the 2v carb too ;-)

I would look into an edlebrock carb. I realy like mine it is easy to tune and works fine as a daily driver carb. There are also not as many gaskets that can leak on an edlebrock carb.

I hate edelbrock carbs personally. They never have given me good performance on my cleveland (been through 2). I had a holley 3310 600cfm for a while. It did alright, but off the line power is much better now with my holley 770 street avenger. The street avenger was designed from scratch to be a great performing street carb that provided good fuel economy/part throttle acceleration. Speaking from experience, I'd put a 670 street avenger on for your purposes.
