SBF - Th400

[Nokooler]

SBF w/TH350/TH400.. This sounds soo stupid, I know. It'll cost some cash to build my t-5.. I did find a cheap Liberty built T-5.. But within a couple years, I'm hoping to have a 5.3L truck motor . Anybody else do anything like this?? Just looking for simple info. How did the crossmember work out? Perform better than a C4/aod?
Keep in mind, I was running [email protected] with Slicks, 1.82 60'. I was thinking just a high stall, then spray it down.

At that kind of power I think a c4 or aod is fine and much cheaper. Most people go to a Th400 or power glide when they start making a ton of HP and get sick of breaking c4's. If it's mostly a street car I'd just throw a decent AOD in it. With a good converter and some nitrous they work good. At your mph now with a 150 shot and an aod it would probably run 11's on spray. And even with a 4.10 gear be able to drive it to the track. Least I did with my 91 vert.


Just for the Bellhousing to bolt up a th-400 to a smallblock ford your looking at $300+ and it won't really be bolting upto a chevy motor again unless you change it again or get a new case. You can see what I had to do to my trans mount to make my Th-400 fit but my motor is as far back as it will go.

Have you talked to Rich @ Detroit Gearbox? I am willing to bet he can set up your ford trans to handle the abuse, and I would suspect the price wouldn't be a nut kicker.

and im pretty sure you can also get a t5 to bolt up to a 5.3l if you wanna go that route
i saw it somewhere on ls1tech and it was pretty easy

For some reason I was thinking it would be a bit easier to go auto in the long run.. I thought about the AOD, but I heard they are a bit more money to build than the c4.. thus making the 5.3L not as cheap as I thought.

No I haven't, I was expecting around the area of $700-$1000 to make it last.. My trans really needs to be gone through x.x.

I looked into that as well.. That was my original plan, but I was thinking I would mess up my T-5 again .. x.x.
I'll call Detriot Gearbox after Christmas.

I agree with the C4 deal. Your not making enough HP or going fast enough to worry about it. A C4 will handle an 11 second car for at least few summers with abuse before needing anything.

I also just picked up my C4 from rich today actually. Not a terrible price, and we upgraded some hard parts too. I'd definitely give the man a call when you think your ready.

I've been 10 teens at over 140 with a C-4. I will be seeing Rich for a trans upgrade this Winter though. I'm gonna be pushing the limits with my C4 with the new combo

Thanks guys. My car was originally an auto car, its kind of cut up by the shifter. Not sure if that affects me using a C4. I'll probably call Rich and look into getting my T-5 rebuild/beefed. If I go c4, it'll have to be a 3.08-2.73? geared car, with a turbo. I'll be a SBF for a few more years now .
