Re: Ford vs Chevy Build-up
 

Looking good Rich!! How's the engine coming along for it?

Re: Ford vs Chevy Build-up
 

Probably have the engine ready by next weekend Tony. The real hold up is the transmission...still nothing to go with yet.

Re: Ford vs Chevy Build-up
 

PM sent about transmission

Re: Ford vs Chevy Build-up
 

After a brief foray investigating a 4R70W transmission using a lock-up convertor it was determined the car would never have enough hp to take advantage of it. Back on track now for a C4 with a lower gearset. Still have not located a suitable core.

Re: Ford vs Chevy Build-up
 

Rich, what kind of paint did you use on the interior? Sorry, you may have mentioned this in a previous post, however I can't find it.

Thanks,

It was two different types of SEM...one for vinyl and another for plastic. Both came from LateModelRestoration. http://www.latemodelrestoration.com/...aint-Spray-Dye

Re: Ford vs Chevy Build-up
 

I'll be able to button this up as soon as I finish manicuring the scraper. The lack of a C4 still plagues the project.

Re: Ford vs Chevy Build-up
 

Looks good!! As I told you on the other forum, just grab one of the large bell trans, as long as it's case fill. I'll give you a small bell for it, just pay shipping. Or get this '70 model trans I have and let your builder change out the front drum to a 24 spline unit from a '71 and newer. That's the only difference. You're getting close, I'm interested in seeing how it runs.

Re: Ford vs Chevy Build-up
 

Thanks Tony - I found a fellow in KY who says he has one. If he gets back to me I'm going to let him ship it directly to Arnett.

Re: Ford vs Chevy Build-up
 

Ok guys...when you stop laughing can someone remind me what the heck this hole was used for? :confused:

Re: Ford vs Chevy Build-up
 

On my 88 Mustang it isn't for anything. Just a threaded hole that goes nowhere.

Re: Ford vs Chevy Build-up
 

Thanks Mitch...upon further inspection it is indeed a blind hole, so I can put it out of mind now. :)

Re: Ford vs Chevy Build-up
 

Your welcome sir. Cool build.

Re: Ford vs Chevy Build-up
 

Looks like I have a choice of 2.82 or 2.90 gearset in a C4. What would be preferred in this car at nearly 3400 pounds w/driver?

Re: Ford vs Chevy Build-up
 

I think the blind hole is for a knock sensor, not sure what year it's used. Mine is a 95 and doesn't have it. At one time I thought the sensor could be used to watch detonation closely to control ignition advance, but I bailed on that.

Re: Ford vs Chevy Build-up
 

2.92 low and 5.14 rear gear with 29.5" tires..................it's magic.

Re: Ford vs Chevy Build-up
 

I've got 4.56 with 26" tires.

Re: Ford vs Chevy Build-up
 

Thanks!

Re: Ford vs Chevy Build-up
 

A 26" tire has a rather small footprint. Kinda livin' on the edge there Rich..........
A very little spin is a bunch of et in a slow car. Hope it works for you.
BTW, your build is stunning, big attention to detail, way nice!

Re: Ford vs Chevy Build-up
 

I think that hole was used for some sort of an emissions tube on some vehicles.

I would go with the 2.92 first gear.

My car worked very well with 26" tires. I am thinking of going back to them.

You will have no problems.

Your car is looking great.

Re: Ford vs Chevy Build-up
 

I figure I will be down on hp just like our other car lol. Couple that with the weight I doubt I will have much issue with tire spin hehe. :p

Re: Ford vs Chevy Build-up
 

Some trial fitting of components shows slight interference between the fuel rails and lower manifold...just a touch with the die grinder will remedy that. As I suspected the rockers will need just a tad more clearance with the stock valve covers...I can either double gasket them or run an aftermarket set I have on hand. The tall covers present even more problems with interference on the upper plenum not to mention the inability to remove either cover without pulling the upper plenum first. I'm thinking stick to the factory pieces.

Re: Ford vs Chevy Build-up
 

Keep the factory pieces and clearance the inside of the valve cover. Parts are on the way.

Re: Ford vs Chevy Build-up
 

Did you paint or powder coat the valve covers and intake?

Re: Ford vs Chevy Build-up
 

Just some leftover paint I had from the trunk. :)

Re: Ford vs Chevy Build-up
 

Due to looming time constraints and the seemingly lack of C4 cores I bought a race ready C4 from Dynamic Transmission in Conn. It will be a fwd manual valve body, rollerized and equipped with a 2.90 gearset.

Had I known it was going to be such a problem locating a core I would have began my search much earlier. When Arnett told me he had not located one I knew I was in trouble. I'll still get Thomas to build one if a core ever materializes for a spare. All I need now is to get a convertor spec'd by ATI or someone else.

Re: Ford vs Chevy Build-up
 

I probably should have mentioned this earlier, but I didn't know that you were in the market for a built C4 instead of just a core.

Ed Horensky who I believe is a member of this site is very, very knowledgable about C4's. I highly recommend that you look him up.

I sent the C4 in my Super Stocker to Dynamic for a rebuild. They did a very nice job, and seemed to have worked out some longstanding problems that I had with the trans brake. They are a good shop, and I'm sure that you'll be happy with them. I still would strongly recommend that you talk to Ed. He has information about many things that will be helpful to you.

I used JPT converters for a long time, but switched to Coan when Jim retired. I'm very pleased with Coan for many reasons. Excellent shop.

Several guys I know switched from other converter builders to Ultimate and picked up. You may want to give them a call, or Coan.

Nothing against ATI, but they would not be my first choice for a C4.

Re: Ford vs Chevy Build-up
 

I wasnt in the market for a built trans until recently when I realized a waiting on a suitable core was going to seriously put me behind. I would be interested in other's experiences with different convertors...this is not set in concrete yet. ;)

Re: Ford vs Chevy Build-up
 

is that spacer legal between the manifold halves?

Re: Ford vs Chevy Build-up
 

Likely not...I have that almost sorted out.

Good eye Bob............

Re: Ford vs Chevy Build-up
 

i see. very nice build.

Re: Ford vs Chevy Build-up
 

Thanks to Aaron, the Speed Doctor for the excellent alternator bracket.

Re: Ford vs Chevy Build-up
 

You may want to consider a C5 core. It's a later version of the C4 with an improved case. The band adjusters are metric, I believe, with fine threads. It also has better fluid passages. You would need to change the bell housing to a C4 housing since the converters are different. But, they are nice transmissions, and worth a look. I believe that everything else in them is C4 (I can double check for you).

Some builders prefer the C4 by default because from what I can gather they are just used to building them. But, again, there's really no difference between a C4 and C5 other than some case improvements. From what I see the C5 seems to be a better transmission. I'm building a K/SA for my son, and will be using one.

Follow up: There may be some other differences. Going out for the day, but I'll take a closer look when I get back. Nevertheless, you should look into them.

Re: Ford vs Chevy Build-up
 

C5's have a deeper bellhousing due to the deeper lock up converter they used, but have a improved oiling system that is a plus.The valve body is unique and is usually traded out for a C-4 valve body. Front band adjuster is a fine thread that is a 2:1 ratio to a stock C-4 course thread so you have to double your band clearance turns to 3 turns instead of the usual 1 1/2 turns. They are good cores to use if you swap the bellhousing for a C-4.

Re: Ford vs Chevy Build-up
 

Not to take this thread off topic... Question,

What years and models was the C5 trans used ? Also, any visual markings or way to indentify them once removed from the vehicle? I would like to have a couple of good cores under the bench just in case.....

Thanks ,

Re: Ford vs Chevy Build-up
 

May be unrelated, but I seem to remember reading at one time Ford used, or was planning to use a sensor running off either the flywheel or rear crank flange to read a signal from. Possibly that is what that hole was for, acsess for a sensor?

Re: Ford vs Chevy Build-up
 

I need to purchase a flexplate and have noticed two different configurations for a C4...one with a single step and the other with a dual step. What/why the difference and which do I need? :confused:

Re: Ford vs Chevy Build-up
 

That is a nice piece.
