Hello. Im planning for my next engine rebuild and I was interested int dual carbs. I've never messed with multi carbs, just single. Very basic stuff. I heard from a friend that the first carb was the main one the engine runs off of, and the second kicks in based on throttle position. In theory this sounds awesmome but I need some input. I know pretty much nothing about dual carbs. Im aiming to build a very streetable 350, but with some kick. Maybe even a 383.

Basically are dual carbs streetable? are they hard to maintain? And would they be worth putting on this engine?

Thanks for any help at all!

 

Dual carbs are good for looks but are not needed to feed a 350 or 383 engine. The engine will only inhale so much air regardless of how many carbs you have. Until you get comfortable with carbs, make your life easier and use a single 4 barrel of the proper size to feed you engine. Better yet, if you have the cash for dual carbs, go for FI instead.

 

Thanks pete. I also have a few questions about 383s. Do you know much about them?

 

There in not much to know about them, except that they are a stroked version of the 350. In the old days they would take the crank from a 400 small block and cut down the main journals to fit the 350 block. The 400 crank was externally balanced, so a flywheel with counterweights was needed. Now you can buy a stroker kit with a new crank and it can be ordered internally or externally balanced. New pistons with the wrist pin moved up are needed to compensate for the added stroke. In some cases the rods may hit the oil pan rail, so some grinding may be needed to prevent it.

 

Wow u just answered all my questions haha thanks a lot man!
