I need some suggestions.

I can't seem to leave well enough alone. My 170 is fun, the way it runs and the Fairlane's gearing make it get up and move. It basically sprints up hills, without the gas floored. I'm guessing around 120rwhp right now which is better than stock. I eventually want to turbo it, but I have other things to do first.
However, I am considering a new carb for it. The thing that bothers me about a new carb is the chance of getting too much air and fuel into the engine than the stock exhaust manifold can put out.
Right now I'm running the stock carb on the stock head, however the head has a 3 angle valve job done as well as the solid lifter rocker assembly (I'm not sure if you'd count that as part of the head).
For exhaust, it's the stock manifold (without the port divider) and original piping to just under the firewall. From there it increases to 2.25inch back to a Flowmaster 40 Series (the original style) with the center of the casing being about right in line (from side to side) with the right rear foward spring shackle. After the Flowmaster the pipe makes about a 90 degree bend, goes through a splitter and the two pipes on the splitter exit directly in front of the right rear tire.

Should I get a new carb first or should I go to a header with a port divider first. Or, should I get a port divider only first and go from there?

Howdy Blueroo:

IF you're still using the original '64 170 Autolite #1100, with a stock type Load-a-matic distributor, you can easily move up to an Autolite #1100 from a '65 200. It will increase your cfm from 150 to 185. And it is compatible with the Load-a-matic distributor. This is a nice upgrade for a 170, even in stock condition.

No need to worry about the carb overloading your exhaust system. The engine will only draw what the engine can use, and that is dictated by the weakest part or the tightest bottleneck.

The 3 angle valve job and the mods to your exhaust system will help to accomodate a higher cfm carb.

Tune with a little more initial advance and the highest idle vacuum.

Adios, David

I am using the stock distributor, but it has a pertronix ignitor 1 kit. How much price wise am I lookin at for a '65 carb.


One ohter thing. I at least believe it's the stock 1100, although I got it on a core exchange at Autozone. The housing looks a little different, it almost seems to have a "dead spot" on the carb body for if it was to be used with an automatic trans.

If you are going the rebuilt route ask for a '65 or 66 Autolite 1100 for a Mustang 200 six cylinder engine. If you have an auto trans specify that too.

Price will range from store to store but in the $80 - $100 range.

Caution!!!! Do not believe that a rebuilt carb is correctly or carefully rebuilt. Disassemble and inspect to verify correct settings and cleanliness, tight shafts and that all gaskets are in place and sealing.

Personally, I like to fine good cores and rebuild them myself. The kits are less than $20. They include good directions. Add a can of carb cleaner some time and you're in business.

Enjoy!
