G,day fellas. I have been a reader of this forum for about 2 years now, which is loaded with good information and interesting topics. I would really appreciate it if anyone can help me with my querry. Where is the best place to get a C4/C10 transmission built with the following specs: full manual valve body, transbrake, that can handle up to 600HP. Thanks.

G'Day JEZZ, welcome to the forum.

It might help if you let people know where you are from so they can give you some leads in your local area.

Cheers

Good Idea. I live in South Australia, about 400km out of Adelaide. We have our own 1/8th mile strip which is called Steel City Drag Strip. I am willing to obtain transmission from anywhere in Australia. Here are a few details about my ride.

XTGT Ford Sedan ( Running gear not original )
351C, C6, 9 Inch with 4.56:1
Engine Specs: 12.7:1 comp, Stuffed 4V CC Heads, Funnelweb intake, 750HP Holley, 260 deg at 0.050 cam, about 0.600 lift. Block is 0.030 over with 2 bolt mains. Block is studded, both mains and heads. Crank is 4MA. Rods are stock, but have been ground and polished and bushed for fully floating pistons.
Best time is 7.46 on 1/8th mile.
I have a 5000 converter, but can only stall up to 2000rpm on the brakes.
I need a transbrake so I can launch at 5000rpm, car should ET better. My current 60 foot time is 1.76.
I am considering swapping c6 for a full manual, transbraked c4.

Cheers

Hey, there some pretty good times there. Looks good for a mid 11 on the 1/4, but like you said, being able to stall it up more and launch harder will see your ET fall more. Might get some front wheel "air time" with those 4.56's

Its hard to beleive you only 60 foot at 1.76 leaving on the brake at 5000 rpm with that motor. If the motor is making the power (and you get good traction) it must be the converotr, or tune holding it back.
I assume you run slicks, so how is the traction?

If I can do a wheel stand and run a 10 sec 1/4 in a street driven car I,ll be a happy man.

It should 60 foot quicker if I left the line at 5000 rpm, however I can only foot brake it to 2000 rpm. I am getting good traction with 28 x 9 Hoosiers and slapper bars.

You could try having a chat to Neil at Precise Automatics in Brisbane. He may recommend someone closer. Just a thought. Ph # 3287 5270.

Thanks for that, much appreciated. I searched through previous threads and found Trans shops such as DMT and KEAS. Has anyone had any success with transmissions from any of these guys?

Cheers

How many inches in diamater is the stall convertor. As it sounds like you have a 9 or 10" convertor. A 5000rpm convertor for a natural motor is 8" in diameter.

A 5000-5500rpm one for a blown motor is 9" in diameter. I have one in my garage.

PS..Don't buy a trans from Vic. QLD, NSW and WA to an extent have decent builders. Be prepared to pay upwards of $2500. I know someone who was quoted $5000 for one.
