FEDDO Car looks great. you will never regret using the 4100 carb,either the 1.08, or the 1.12. think port velocity. i would put in a set of flat tops and a set of 69-71 ,351 windsor heads cut .060 and run the car. makes for a nice combo.

Update?

I like that you're doing something with a Granada. Let us know how things are going with it. There is a project car like yours on http://www.StreetClubTV.com you should check it out. I think you'd like it.

sixty9santa Does anyone know if these nitrophyl floats (Motorcraft CM-1062-A/Ford D4AZ-9550-A) will work in a 4100?
I know that they are listed to work in the 2100, but not sure is these floats are the same for both primary and secondary?
Appreciate any and all help,

Chris

sixty9santa Thanks for the kind comment!
I guess I'll keep getting the parts as cash permits and when all is waiting to be assembled, I'll be back for more great help.

So back to the Autolite 4100, I've managed to get my local Ford dealer to order a rebuild kit (Motorcraft CT-191-A) for 36$.

As I've been doing some more research, I've discovered that the original brass floats will all fail at some point, just a matter of time. The alternative are the nitrophyl floats. I believe that they are still available from Ford (Motorcraft CM-1062-A, Ford D4AZ-9550-A) but I'm unsure if I've gotten the proper part#?

redlightning That car is going to look great with those wheels and sound great with that exhaust system.
I would drive it that way and enjoy it.And get a 302 or 351W and build as you have time and money.

sixty9santa Thank you for the advice and I'll steer clear of the "P" heads.
Instead, I'll save up for the Edelbrock Performer RPM Top End Kit to keep things simple on my first build.

I know that removing the engine from the car is the best way so I may have a question that might be completely stupid but, can I change my pistons with the engine still in the car? Could it be done, safely?

I ask this since I have absolutely no space for the car in the garage, not to mention that an engine hoist is out of my budget at the moment (no possibility to rent either). I can get a complete set, minus rings, of +3cc hypereutectic pistons from Summit Racing for about 90$ (part#: SUM-17302-00) and a set of moly piston rings (part#: SUM-133-M139-00) for about 36$ that should work with the above mentioned pistons.
Would this be a wise thing to do?
Would +3cc pistons work with a 60cc chambered heads to get my compression between 9:1 and 9.5:1 with a tall deck?

I know that I must be irritating with all my newbie questions, and I do apologize for my lack of experience and knowledge. Feeling kinda dumb,

old fords over on the maverick site some members have put GT40p heads on their cars with 6901 headers and they say that it will burn up the wires and you have to use shorty header plugs. If I were you I would get a set of regular GT40 heads for it

Thanks for the input timothale, I was also told that doubling and even tripling the booster gaskets is a good thing to do.......why?

sixty9santa Thank you for all the advice!

I talked to Pony Carbs last week and told them that I was considering using the Edelbrock Top End Kit. Before calling Pony Carbs, I contacted Edelbrock, they said I need at least 9.5:1 compression (I agree) and a 650 to 700cfm carb......which I find excessive.

I called Barry Grant the same day, and they suggested a 650cfm Speed Demon......I think it's too much.

After contacting Edelbrock and Barry Grant, Pony Carbs informed me that seeing that the Autolite 4100's flow about 550cfm, I should be fine, and to call them when all is setup so that they can send me the proper jet sizes.
There was an independent test done to SAE standards (I forgot the link since I printed it but it was Charlie's Automotive in Apex, NC), and it was discovered that the 4 of the "big" 1.12 venturi sized 4100's flowed 503cfm, 523cfm, 526cfm and 528cfm.....I was shocked!

Pony carbs also informed my that 95% of the 4100's have the exact same casting, with the exception of the venturis of course, and therefore they could configure my carb for my needs.

So currently, I believe that the only thing holding me back is my pistons.......and money...........and complete lack of experience

carb.

I always liked that old long body 4 barrel carb...things to do... check out the casting lines inside the bores ...usually they have sharp ridges where the mold didn't line up . sand paper and a stick and polish the air flow thru the carb. then a new rebuild kit and check that every thing works choke operation, choke unloader you can adjust ignitiin timing and accelerator pump to work together off the line. and I used to bend a 16 penny nail and weld it to the primary linkage so at full throttle it would kick in the secondaries with out the vacuum pull...

onebadmerc If it is a early 76 engine it will have 58cc heads, Ford didn't change the heads to a 69cc chamber until late 76. Your compression ratio is really low due to a deep dish in the pistons. Even if you find a set of pre 66 289 head with 54cc chambers and bolt them on, your compression won't be more than 8:5 to 1. The Autolight four barrel you have is designed for a big block engine in a heavy car. That carb will make your car run even slower. If you go with a Autolight 4100 find one calibrated for a small block, flow ratings are around 480cfm otherwise use a Edelbrock 500cfm four barrel. The 2 1/2" exhaust is going to kill all of you bottom end torque, I would step it down to 2 1/4". I don't have much experience with the Edelbrock knock off intakes, but if it was me, I would spend the extra $50 and get a Edelbrock intake or a Weiand intake. You do have a good looking car there and it would be a good car to hop a little bit, but don't expect much out of it with your dismal compression ratio.

techinspector1 I'd need to know the volume of the combustion chambers, piston crown volume, piston deck height volume and head gasket volume to properly figure the SCR.
12-08-2008 12:39 AM
sixty9santa I have a chance of getting some ported and rebuilt 302 HO heads for near nothing, 200$.
Should I?
What compression could I get and what cam should I be looking at if I get the heads with the above list of parts?

My girlfriend even said that they'd be my Christmas gift!
12-06-2008 05:14 PM
sixty9santa techinspector1, none whatsoever!
12-06-2008 05:09 PM
techinspector1 Are there city or provincial laws or regulations which would look unkindly on modifications to the car? Will the motor have to pass emissions testing?
