Which carburettor

Hi all, how can I find out which carb number should be fitted to my 73 Chrysler CJ 360 ? As on my post in the eng/carb section it's running too lean at idle & light throttle & ive tried most things so I'm wondering if someone has fitted a different carb on it before I owned it. I can't seem to find much info for carbs fitted to Aussie cars only USA models. Thanks shaun

Just been looking on the carb doctor website & it lists all 360 with 2 barrel as having a holley carb but mine has a 2 barrel carter bbd ?

I think it should be a Carter, not a Holley from the factory but a Holley would be a good replacement which will work if set up right. It may be someone has bolted on a carb from something else with no changes to jets.

Worth getting a good 2nd hand decent carb then having it set up by someone that knows what they are doing.

You can play yourself and get it in the ball park but to nail any blips in the curve you need someone that knows the insides of one.

I found my ignition system upgrade helped also, big time.

Checked the I'd tag on my carter carb today, it's 4962s which looks like is meant for the 383 engine

should do the job unless someone has strangled it with the wrong rods n jets

think a carter 2 barrel for a 383 is a different Carb (visually at least~) to the carter BBD used on the smaller engines (318 and smaller) and jeeps

i.e it takes an air cleaner with a hole in the base more or less as big as a 4bbl

whereas the BBD is quite small

it might be worth investing in a 4bbl intake and putting a 600 vacuum secondary Holley on.

it will work well in a low compression 8:1, auto trans car, with a normal OEM cam and 2.77:1 rear gears

i'm guessing the original Holley was modelled along similar lines to the 2 barrel Holley 500

headers cam etc then something a bit more would wake it up

Hi Dave yes it is a bigger bed carb. I've checked the parts catalogue & it should have a Holley R6178A apparently but I wouldn't mind going the 4 barrel route if I could find a good secondhand one maybe

Here is a two barrel Carter on a 383.

Mine looks very similar to that, I've took some photos but how do I upload them on here ? Shaun

Resize the picture in picture manager to less than 256kb (I usually do about 15% of the original size image, the save it with a new name so you don't destroy your original picture, then post it up.
