I am thinking of ugrading my carb from the standard 2 barrel Carter carb on my 68 Dodge Polara (383), I feel it just needs a bit more power, any recommendations on the best 4 barrel carb brand size to go for holley, carter etc, been having a look and it seems theres many options..... the engine is the stock factory 383 with original 2 barrel carter carb, any help/advice would be great, cheers

600 CFM is probably the biggest you want to go. Get you an Eddy Performer or RPM Performer intake.

Agreed. An Edelbrock Performer carb with a Performer intake....

OK will check it out, thanks for the help

Just had a quick look, any ideas which model is best fit, seems theres a few choices, looking at the 14064,1405 & 1406

78D200

14064 - This is the "shiny" version of the 1406
1405 - This is the basic that Edlebrock puts out and has a manual choke
1406 - This is the same as 1405 except instead of a manual choke, it is electric.

If this is a show only car, spend the money on 14064. If this is a car that you drive around then I'd go with the 1406, wire in the electric choke and call it good. Also go with a Edlebrock Performer intake and a new air filter kit. This will help build some power. After that think about going with a set of headers to help exhaust all that fuel and air your new intake system will want to feed the motor.

OK thanks for that info, looks like a 1406 will be best fit, as its defintely not a show car :-)

if its a stock set up i agree 1405
or try the 1805 650 its a spread bore and avs
i use that on a air gap rpm feeding a 318

Your running E-85?

yeaaaaaaaaah, you won't see too much power out of this, but i'm sure something. oddly, the biggest power gain i got out of my '68 was removing the mechanical fan in favor of an elec job. i could feeeeeel that modification in the driver seat.
