Anyone know if...

[Stangman]

If there is a such thing as a Big Block C4 bellhousing???? I dont want to run the C6 that came with the 429 I have... I'd like to keep my transmission tunnel... and will I have to run a different converter and flywheel??

Also, with a C4, can I run my dead-stock '85 automatic shifter? I want total sleeper quality here

[mustangboy]

Yes there is a big block c4 housing, I have one on my car. They came out of believe station wagons. Not sure on the converter and flexplate. I believe there is a way to convert the shifter to work but not 100%. I think dedpedal made a stock shifter work with a c4 check with him. Also don't forget 460.ford.com, you can probably find all your answers there.

[Stangman]

Sweeeeeet... but what kinda of wagon?? also... while helping a friend take apart a dash on an '85 GT I noticed on the back or the top of the guage cluster that the tach calibration can be changed to 4 6 and 8 cylinder.... Are the 4 cylinder clusters the same way?? I want one because I do NOT want to put an aftermarket tach in it at all. I want the inside ALL stock.


So it looks like a bellhousing will cost me some more money on top of the $941.78 minus tax and shipping that it costs to put a big block in a fox.... :rolleyes:

[mustangboy]

A BIG wagon:D As far as the tach goes I believe that is just the earlier ones. I don't know if you are anywhere near putting your drivetrain in the car but whenever I take mine back out I'm gonna switch to an SFI bell. Now if things go as planned I won't have to pull my back out till this fall/winter when I hope to strip the car for paint. However with my luck I will have to pull it before that.:rolleyes:

[Stangman]

I am nowhere near the stage where the drivetrain goes in the car (except in my head) but its nice to know these things before hand...

just out of curiousity... there isnt a 5 speed that would fit nicely in there would there be??

[mustangboy]

Unless you really baby it a t5 won't hold up to that much torque. So you are left with a toploader or one of the TKO's either way you are going to start getting into some big $$$. A toplader can probably be done cheaper but will require a bit more fabrication work. I saw a guy who had a complete TKO600 setup for a big block that was $3k and that was a pretty decent deal considering it came with everything you would need. Just keep your eyes open for one of those bells, I think they are not all that common. If it works out I will sell you mine if I have to take my engine out.

[Stangman]

Yeahhh... I think I will just stick with an auto, yeah lemme know on that bell

[Gearhead559]

they make one. but a built bb will need a built c-4. just build a c-6 hell stock they'll take twice as much power as a mild built c-4. and the c-6 is way more durable then a 4. c-4s are lighter and weaker. if you want durabilty then build a 6. if you want more info on building a 6 or 4 just look on the 460ford.com site

[quickt]

Yeahhh... I think I will just stick with an auto, yeah lemme know on that bell

TH400 is a very good choice. Stonger than both c-4 and c-6.

[transman]

i can build u a c4 that would kill a c6 lighter and less power robbing then a c6:bigthumb

Thats what I was gonna say.

[Stangman]

You can get a TH400 to fit a Ford bigblock???

[mustangboy]

Yeah but you are going to be getting into some big money again. You will need a bell that will be at least $300 proabably more and you will need to fabricate a crossmember to work. If you want to keep it easy and as cheaply done as possible a c4 will be the way to go. You can build one that will easily stand up to the power you are looking to make. If you were looking to build a 700-1000hp street monster I could see going the 400 but you are just building a stockish big block.

[Stangman]

yeah, just a stockish setup, cam and carb, since a different intake wont fit under a stock hood

[transman]

ive seen th400 break the lugs off the inside of the case with a 500 hundred horse car well the pinks camaro had a th400 in it and it was destroyed just food for thought

[JIMS SVT]

They will all break.Doesnt matter.

The 400 case lug issue has nothing to do with HP. Can happen to grandpa's pick-up truck. Line pressure and poor snap ring is only cause of case lug failure. Good builder can fix this forever. Most builders crank the main line well over 200psi and this will kill the case in short order. Guess they have no Idea that 170psi will handle 2000+HP. If you are going to spend money on a trans do it once. No matter how much cash you throw at C-4 the old 400 in almost stock form will be much stronger. Not taking anything from the C-4 its a great little transmission. For strength and reliabilty not in same class as TH400.

[quickt]

Yes not a problem for Th400 to BB Ford.

[Stangman]

I'll prolly just stick with a C4 just for ease and budget purposes, the car isnt going to be wild by any means, I just need a trans that will hold for possible daily driving and hold when I feel like playing with it at the strip a few times. nothing crazy, very mild stall converter, shift kit, and enough guts to handle the torque of a near stock bigblock ford

[Gearhead559]

i can build u a c4 that would kill a c6 lighter and less power robbing then a c6:bigthumb

i can build a c-6 to handle twice the power your c-4 can and for less then half the price.and when its all said and done. c-6 wont break no where as much as the c-4

and once you rollerize both, theres only 10-15 hp difference. those lighter internals just arent worth the parts breakage IMO


TH400 is a very good choice. Stonger than both c-4 and c-6.
how do you figure that? the th400 is not stronger then 6. hell i seen 8.00 out of a stock c-6 input shaft. granted both trans rob some power. both can handle around 2000 or so HP. but the c-6 can do it on stock internals

[transman]

[QUOTE=Gearhead559;362053]i can build a c-6 to handle twice the power your c-4 can and for less then half the price.and when its all said and done. c-6 wont break no where as much as the c-4

iam not trying to get into compare what i can do and what u can do but i have atleast two of my c-4 in upwards of 700 hp cars with two years on them no problems

[quickt]

[QUOTE]how do you figure that? the th400 is not stronger then 6. hell i seen 8.00 out of a stock c-6 input shaft.

This debate has been beat to death. I figure cause this is what I do for a living. Best to look at fast cars and see what they run. Very few if any run c-6s. I personally have never seen a C-6 in any 10.5 cars or Pro mod blah blah. The Glide is the most used the TH400 is next and Brunos and others are in the mix. The trend these days is to remove PG and install 400 and cars are going faster with the 3 speed. These guys can run any trans they want. They choose not use the C-6. The 400 has earned its reputation out in the field in fast cars that make big power winning races and hanging tough. Enough said.


granted both trans rob some power. both can handle around 2000 or so HP. but the c-6 can do it on stock internals

I would love to see the 2000HP on stock C-6 or 400 for that matter. The point is not what can be done with stock parts. You can put huge power threw something stock for short period of time. People that race their car competitive understand that you can’t win a race if you are broke. You install superior parts for durability to make pass after pass to get a chance at the final round. I meet many people that will spend thousands on the power plant and want to use a basically stock transmission and wonder why it’s broke. Some will get by with it. People remember the guy that ran stock parts for a million passes but seem to forget the hundreds that blew thier stock stuff all over the track.

multible c-6s behind 1500 plus hp cars. c-4s has there limit(around 900-1000hp at best.) trust and beleave on that.

and quickt maybe you need to look more in to mugdrag trucks. those guys are making crazy hp. the guy that builds the best c-6 trans brakes builts these trans mainly with stock parts. his car is deep in the low 7's with mainly a stock c-6 parts in it.

and no shit. the glide is where its at. but by the time you build one to take crazy hp. nothing is stock now is it. only then do i feel right putting one on the generals parts in my car.

[mustangboy]

Just in case anyone cares I did see a JW th400 setup w/ sfi bell and convertor posted on 460ford.com for $1500.

The C-6 is much better for a pick-up truck.
Yea we all knew a guy one time. I referenced that in my last post.

Glide is being removed in favor of 400 for some racers. I personally am not a glide fan.

I figured this was the real issue.

Thanks for the info. Apples and Oranges but thats cool.

Sorry Stangman for the thread Hijack

[Rick93coupe]

After much research and talking to literally dozens of people, I chose the 400 route. Some old school guys tried to talk me into running the C6 because of their own issues of putting GM parts on my mustang, but I was more interested in reliability and repeatability to let that come into the equation.

Yeah I don't post much over there but I do lurk around gathering info. It has been very helpful at times. I will probably start a thread about my build once I finally hit the dyno and have some real #'s to talk about.

frank only freshens his trans every winter. one hasnt yet.(its a low 9 car) and has been runnning 4 full seasons on it. changing fluid every 25 pass's(about 15 time a season) and is still running the same time it did when it first went in the car. so what was you saying about reliability and repeatability.

i posted the link to the k member spacers thread in your other thread for you. hop it helps. theres lots of BB's under stock hoods on there.;)

[mustangboy]

I already have the spacers. I was gonna run a stock hood w/ just a 82? scoop but found a good deal on my current hood. They did drop the motor down quite a bit.

[Stangman]

Wow... I'm gone for a few hours and my thread goes crazy :lol:

Heres the way I am looking at it for what I want to do: (Which may or may not be right)

Whats a stock '69 429 Thunderjet make in horsepower and torque?

How easy is it to put a C4 into a fox than a C6? or vise versa?

What costs less?

With a 429 using stock internals, just a standard rebuild, and a mild cam, performer intake, carb, and headers... how much more strain on a built C4 would that be???

Like I said, I dont want the car to be anything insane no 700hp monster, I want a car that would be very nice to want to drive everyday and look as stock as possible.

If it ran like a very mild 5.0 coupe in comparison that would just fine.

i have a torino gt scoop on mine. its on a 4" cowl now but with the spacers, i should be able to run a 1.5 or 2" cowl hood.

If cost is only concern IMO the C-6 would be best choice for strength over the C-4. No wrong choice here all three will get the job done.

[Stangman]

What would be the easiest to fit into a fox? without cutting the trans tunnel or anything else rediculous or unnecissary??

[mustangboy]

Check with the guys at 460ford on if you use the k member spacer and still have to beat the trans tunnel in to use the c6. They may drop the engine down enough that you won't have to beat the tunnel. If that is the case I would go that route w/ the c6. I used a c4 because I already had two of them sitting here.

Just giving you a hard time man. The C6 is an ok piece not picking on it. Just not as versatile and widely used as the 400. Not as strong when modified either. I know you are a GM hater and hurts to hear it but its the truth.

[Gearhead559]

i just think your mis-imformed on the c-6.granted there are more parts out for the 400, but the 6 is stronger then you give it credit for.
