are 2-4s worth it

I have a 305 Chevy built up with edlebrock RPM pro.kit (carb. manifold heads cam and lifters) runs OK. Would a2-4s ( carb and manifold) set up be OK or a pain the butt. 2-4s look cool .

If you put two 305's under those two 4-barrels it will run nice.

I like the look,And you can dial them in to perform good.But can be a pain sometimes.Just don't over carb your motor.They work good with the 450's.But if you want the best performance,Stick with one carb...

+1 ^^^

Stick with one carb unless you really want the look. A single carb beats a multi carb setup 99% of the time.

2 X 4's

I heard pros and cons before I put 2 X 4's on my .060 over 283 in a Model A coupe. I only use the idle circuit on the rear carb and close the needle valves and back off the idle speed on the front carb. I used 2 - 600 CFM edelbrock 1405's(because I had them) and contrary to what I heard about the engine being over carbureted the car wales with them on. Being air valves the secondaries will only open when they have enough air flow. Needless to say I am happy as hell and the look of 2-4's with the hood off is priceless and the sound of two fours at full tilt is awesome.

Use progressive linkage with two small four barrels. It will run on the back two primaries until you push harder down on the gas pedal, then it will open the others up.

That would be your opinion, some people want the look, I went the two fours route and it was not a waste of money.

2 x4s are ok but what type a low rise or a tunnelram if you are running a auto trans you will have to up your converter to like 3000 -3500stall, then change the rear gears to work with that.eveything is like a big puzzle all the pieces have to be there for it to work RIGHT. first a 305 doesnt have big enuff heads to beath so add another 1200.00 for heads stick with a single 4bbl unless you got DEEP pockets. the guys who run those 2x 4 set ups dont just stick them on and go.
