scored some FE parts today

[dotcentral]

I bought some FE parts from a Craigslist add today. Originally these came off a 66 galaxy. Autolite 4 barrel (w/date tag still attached), Ford cast iron 4V intake, and a set of heads. At least one valve is broken in one of the heads. I doubt the heads are worth messing with, but it was a package deal and the price was cheap.

I'll have to do some research on the carb. I had downloaded some info on autolites a while back but can't find it. Any got any good sites, info on these?

Intake will need cleaned up and painted, but otherwise looks good, if a little heavy.

Any real difference between truck heads and passenger car 4V heads? Pretty sure the valves are the same size. maybe the combustion chamber size is different?

Thanks for any help.

Hi Tim, post the numbers off of the 4100 tag and numbers on the front drivers foot.

Also, on the front drivers side on the bowl will be a circle with 1.08 or 1.12.

The carb has the 1.12 (600 cfm according to Pony Carbs). The numbers are C6AF-L. The only book I have that covers FE's is High performance ford engine parts interchange, which isn't very indepth. I looked up the tag, and it is off a 66 with cruiseomatic trans.

I got C6TEC for the heads, My book lists a C6TEG, so I might have that last letter wrong.

For the intake I found C5AES425C. Seems like a lot of extra characters, so maybe the last 4 don't mean much. think I remember reading that the last 4 would mean minor engineering changes? Guess I ought to buy a FE book.

I like those 4100 carbs, I had one on my '66. After trying a few other flavors, I found that carb had the best all around performance & ease of adjustment. Do you know you can actually run the engine with the top of the carb off? That, my friends, makes for no-guessing, spot-on float level adjustments.

There's a couple different age groups on those, some will have the smaller Holley jets & others will use larger Ford jets...I forget which style is early & late. I have a few of each flavor, but prefer the Holley jet type because it's easier to find jets for.
The one downer is the secondary vacuum diaphragm on the back...it might be tough to find. In the early 90's, it was still available from the dealer, I have no idea if it still is. I doubt it, but I bet Pony Carbs will have it.
Getting that diaphragm to stay put without warping while screwing the cover on is a pain in da butt. I chopped the heads off longer screws for mine...making them into studs...then slid the diaphragm, spring & cap down the studs & screwed the nuts on. Works great.

1966 352 V-8 WO/Thermactor Autolite 4100 C6AF-L.

The 4100s I have seen have the same boosters and jets for 352/390.

If you bump up your cam and have a free flowing exhaust you can go down a size or 2 on the jets.

Mid 1964 and down had a long accelerator pump body.
I also think this is when they still used Holley jets.

Late 1964 and up have a short accelerator body and use different threads on the jets than Holley.

I have asource for real nice gaskets and parts for 4100s.

You can buy kits or seperate pieces.

The Intake sounds like C5AE 9425 C, I think you misread the "9" as an "S". 9425 is the group number for intake manifolds. However that codes out to a 289 2V manifold casting number which is not even close to your 390 4V intake. Look again it may be end in a "G", not a "C"

Does the intake have holes on the sides of it for pushrods to go through ??

Is it real wide ??

There is an obvious difference between a small block intake and a FE intake. Besides looks, there is the difference in weight. I sure couldn't carry this intake with one hand. I must have a few numbers wrong. The light isn't that good in my garage and my eyes sometimes have problems with reading these things.

I will probably save up and have the carb rebuilt by pony carbs.

Are the heads worth getting rebuilt? Any real difference between them and the truck heads? Thanks for the info so far.

I'm very seriously considering investing in one of the 4160's from Pony Carbs
Not that much more than a new Holly or Edelbrock carb. (I'll have to buy a core)

[dotcentral]

I ordered a rebuilt 4100 from pony carbs on March 15th, received it about 2 weeks later. I decided to put the autolite on my 71 F100 and will put the known good edelbrock on the 66.

I removed the edelbrock carb from the 71 last weekend. Also had the intake boiled out, then I bead blasted & painted the ford 4V intake. Put the autolite on the 71 this weekend. The little pin that the throttle linkage mounts to broke off, had to use a holley bolt on pin. Anyhow, I am using the heat choke on the 71. Set the choke, put about a tablespoon of gas in the carb and it fired right up. Choke worked great. Carb looks brand new, the engine sounds great.

I emailed pony carbs about the broken piece. I'd like to weld the original pin back on the carb, to get it back in the right spot. I don't want to have to remove the carb, mail it, wait for another carb to come back. Other than the broken part, very satisfied - granted I have 0 miles on it. I hope that will change soon.

Now, time to get back to working on the 66.

C5AE-9425-C is 66-67 390 4V

There is no difference in 2v and 4v FE heads

They used the same head for both

[dotcentral]

Thanks Brent, that's what I figured.

I bought the FE book by Steve Christ about a week ago.

Spoke with Pony Carbs, he offered to trade my another carb, but quickly agreed to let me fix the linkage piece on my own without voiding the warranty. It was mailed out to me today.

Hopefully, I'll get a freind over to help pulling the FE out so I can pull the heads and check the mains and see what I got. Plus clean up the engine bay.
