i have an A code 289 with a 6 or 650 cfm edlebrock carb on it. will a paxton fit and work with this carb or do i have to change carbs and what kind and size?

[not2brite]

I suggest you check with Paxton regarding changes that need to be performed on your Edelbrock, if the Edelbrock will fit and match the inlet ports in the box, etc. Most applications I've seen use a Holley or Demon, set up for supercharging.

The Paxton supercharger feeds a box that pressurizes the carb. Apart from different jetting, the floats on many carbs need to be changed to withstand the pressure.

Before you spend 4k on a snail, does your engine have all forged internals? Is the rest of your car equipped to run that power? Your talking about some serious hp change and unless you have aluminum heads and a good engine setup its not really worth it. Just makin sure.

i thought all A and K code 289s could handle a paxton . is this true.

[66GT305PS]

Been running a Paxton (original type) on the K code in my 66 GT350 for 25 years. Using a Holley 650dp, but that would be too much on a standard A code. A 600 might be better of if you have a stock set up A code. I would recommend you check with Paxton or with Craig at Paradise Wheels on the right carb to go with your cam (stock?) and the proper jetting. Another thing, you would do well to put on better exhaust flow with good headers and dual exhaust to get all the extra flow out. And you will need to get the right performer fuel pump. You might consider upgrading our ignition also.

The result is real fun, making your small block feel and run like big block.

i thought all a and k code motors came with autolight 4 barrels if so why the holley or demon carb to be used on the paxton. im hoping my 600 cfm edelbrock will do the job. any help out there?

[shommel]

can they be used on the straight six cars and what about the 260 v-8?

Ok you are going all over the place, what is it you are building? 289 A code? 260? 200-I6?

You can supercharge or turbo any engine, it just take money. If you visit http://www.paxtonauto.com/product.php?id=111 you can see all the options from Paxton. Can you walk in and buy a bolt on kit to supercharge an I6? Not that I know of.

There is a guy on Ford Six Performance running the following Set Up in his car:
His SN is: Mustangaroo
200cu.in. Inline Six, Aussie 2v Head and Intake, Paxton SN-89 Supercharger, Holley 390 4v, 1.60 Rockers, Clifford Headers,
Dual Exhaust, Distributor Duraspark II, Clay Smith Cam 274 / 110*,
C4 Automatic, 8 inch Rear 3:80 Ratio, Front P185/60R14 Rear P235/60R14, 4 Lug all around!

calisponymike if you read my whole post it starts out with "i have a 65 A code gt mustang fastback" the other questions i was asking was just out of curosity. sorry you seem so salty that i ask questions but after all that is what these forums are for. if ya dont like it dont answer.

"i have an A code 289 with a 6 or 650 cfm edlebrock carb on it. will a paxton fit and work with this carb or do i have to change carbs and what kind and size?"

Umm, no you didn't mention anything about a GT Fastback. But on to your question. If this is an original engine and has not been rebuilt with forged internals in the last two or three years, forget it. Unless you only plan to run around 5 psi of boost MAX.

If you have an engine with lots of miles on it, rebuild it or it will be a question of when it will fail not if. You will need to modify the carburetor, the question is can you get the pieces for it / will the pressure box for the charger fit.

[shommel]

you are correct i didnt say 65 gt fastback i only stated aq 65 A code. well the motor has been totally rebuilt to the specs that when it came out of the factory and the correct carb i have on it is a 600 cfm edelbrock. will this withstand the power of a paxton? i have no idea what forged internals are.but the motor is completely rebuilt and runs great.

[Kebean]

Forged internals are things like a forged crank and most importantly, pistons. All this means is they are made out of better materials and can withstand the higher heat and other stress associated with a turbo or supercharger.

On a fresh rebuilt, back to stock you could theoretically run a mild blower. So, a small Paxton blowing a max of say... 5-8 psi. Should be fine. You will need to run 91 octane or better and you will probably have to shorten your spark gap a little to prevent the spark from getting blown out under boost. The carb will be fine if it fits in the air box and if you can get the right floats and jets for a boosted engine. 600 cfm should be fine for mild boost. How many miles does the engine have after the rebuid? Is it broken in or no?

If not, wait till you break it in all the way and also make sure you either read up real well on what you are doing or make sure a professional does it. If your mixture is bad you could detonate under boost and blow your headgasket/engine before you realize it.

first of all thank all that have answered my questions. calisponymike no hard feelings and do appreciate your input. now next question what is a good break in number of miles on a newly rebuilt motor before trying to apply a paxton?
