Trany Help (Race)

[scholtmj]

If you end up picking the TH400, how much do you want to spend? I know a guy with a few TH400s worth about 5k that I believe is selling them for 1k.

I was thinking more in the line of a core and have it built.
I have a line on someone who says they can build it to handle 1500-1700 hp with no problem.
I gues it would depend on the build and what not.
If he is selling a fully built, ready to go trany for a 1000 with some type of warenty that could be in my ball park.
I just need to get my car parted out and get some cash 1st.

I used to know a guy that was running a 79 Camaro with a 555 CI bowtie block, dart heads, all port matched and flow bench tested and 13.5:1 compression. The motor alone was making close to 1000hp. He also ran anywhere from 150-250hp shot of nitrous on it. This was 5-6 years ago but he ran a 400 tranny and I think spent about $1500 to have one built. They are bulletproof if built well. If it were me, I'd spend the money on a 400 over a 350 or glide. the 350 is a good tranny but not as strong, I personally would want the strongest I could get for my money. True it takes a little more power to turn, but it shouldn't break, even if you add more power later.

I also would pick it over the glide because with 3 gears and a small block you will want to keep your motor in its power range. Will be harder to do with 2 gears in a glide.

Well I picked up a 400 that works so I'll use that to get started

I'm sure you'll be very happy now get a trans brake for the bird.

[mcssmostwanted]

Were did you pick up that trans? what size converter did you or going to get?

[Phantom409]

One of my forman her at work is a gear head too and pickup a 400 motor w/ a trany last year.
Well he don't want the 400 so he said he would sell it to me
We haven't nailed down a price yet but with the research I have done 4-500 is the going price for one in good condition.
The cool part is that it was in a car before he got it so I know it works

Converter, I haven't nailed down yet??
I'm thinking a 10" converter for 32-3500 rpm but I want to wait till I get the motor work done before I buy anything there.

The trany will be getting a B&M shift kit for sure!!
No I know this sounds stupid but what's a trans break & how does it work??

[mcssmostwanted]

i got a 10'' 3600rpm nitrous converter it ran me around 600$ Im not sure how to explain how they work but they help the trans life i was told. may be somthing to look into

[1BADAIR]

A trans brake vavle body has a soleniod that locks the trans in reverse and drive when the button is pushed. This allows you to reach the stall speed on the Tc without the car moving or spinning the tires

[mcssmostwanted]

so the valve body needs to be replaced in my th350 to aquire a trans brake?

[Phantom409]

Yes
I did some more digging (Thanks 1BADAIR) on the trans break and I have to put a trans break soleniod in the trany along with some wiring to activate it.
From what I was told it's quite involved because you have to take apart the trany's valve body to do it.
