I decided to buy a new blueprint 383/430 h.p.stroker crate motor for my"57".The folks at blueprint recommend a 750 cfm carb.for this engine.I will be using my muncie 4-speed,the rear has 3:55 gears.
My question is this I am thinking of running 3-2's instead of a single 750 carb,has anyone used this type of combo? Will it be to lean?
My thinking is it would be different and a fun combo to run.Any opinons or suggestions?

What 3/2 setup are you considering? Frankly, there are not many out there worth having.

It's not that it would be "too lean". It would either not have enough airflow to make the power that a 750 single carb would, or it would just be a giant PITA as far as driveability.

If you're looking at an old 60s setup, those are probably 200-230 cfm carbs - they won't match a 750 single carb. The manifold won't mount the bigger carbs you need, and even if it could, probably couldn't take advantage of them.

Barry Grant before he went out of business, was showing/advertising a 3/2 manifold with some bigger carbs. I've never seen one except on a manufacturers midway, I don't know if they ever made and shipped any.

Maybe there is some other decent setup out there, but they certainly aren't common.
