What CARB/INTAKE Combo Would you use?!

Hard to go wrong with a performer rpm intake and a holley 750 vacuum secondary for street use.

Depending on your rear gears and strip usage a double pumper may e.t. slightly better.

if you are going to spin it to 6k I'd use an RPM air-gap and a 750DP of course.

Hello We have a 1974 Dodge Dart Swinger with a 1970 340 std bore ,stock 340 pistons,J heads 202 ,160 valves with a 484 cam and the intake is from Mopar Perfromance and looks like a M1 , It is a SB intake and we have a 650 Holley SB,DP and it works fine. 727 trans. 3000 stall. 323 rear, stock exhaust manifolds with 2 1/2 with 40s flowmaster muffers.The intake did not have any heater hose hook ups or a place for a manuel temp unit ,we put them in the intake. also we have a 4"x14" K&N air filter on it.

I'd run an LD340 or an RPM with a 650dp 4777 with that mild converter. Even a "Street" Dom. intake will do good.

""360LA 360-375HP. 9.75/1 Comp, Headman A body Headers, 2500RPM Stall converter. Streat/strip 727 Built by Hughes Performance.""

What gears and tire size?

""3.55's with a 255/60/15 on the back Believe its a 27in tall tire.""

Mainly due to the 2500 stall, I would suggest the 650/750 vacuum secondary carbs. I would also suggest to choose one with adjustable circuits (IAB's/HSAB's and IFR's) This makes future engine modifications easier to tune.

Intake: RPM/RPM Airgap.

LD340 or an Airgap with a 650DP Holley and I'd change the converter to a PTC 3,500. But that's just me.

It's hard to beat the Performer RPM air-gap intake for that setup. The 750cfm carb is good.
I just looked at summit racing and they have a house brand 750, that looks like a holley knock off on sale for $251. Anyone use one of these carbs?

Well wen't with a Eddy Rpm-AirGap.....

Anybody know about demon carbs? Would you recommend one?

what are the cam specs?

LD340 is a nice unit but its usually better to go with a new in production and readily available part. I say the Perf RPM/Air Gap or a Weiand Stealth. I had an LD340 on a 340 and it was great- However I knew first hand is was not an overmilled unuasable part.
