Need TH400

[smokinss]

I've got a built th350 in my ss that came out of my buddies 8sec turbo car and its held up just fine for me.

As far as a converter don't be cheep. I spent more on my converter from fti than I did the trans. Converter cost me 850+

Ya i'll be calling yank for the converter to be specd for my set up, id do a 4l80 but a built one is like 3500 bucks screw that id rather spend the money elsewhere and lose a little highway driving. I have other cars for that.

But if this is Not going to be a driver then get a th400. they are just really sloppy for a street car tranny after they get stalled way up and built. could be me?? and i think the programmable shift points and far superior design of the modern tranny far out weigh the cheap and strong th400.

a half ton avalance doesnt weigh 6500. a 2500hd extended cab short bed 4x4 with a duramax is about 6500.

fyi anything under 1000 hp and a strong th350 is all you need........no need for the weight and power loss......

Ive seen a lot of motors under 1000hp rip up TH350's. I just got done rebuilding one that was behind a 481ci BBC that looked like a grenade went off inside.

The 350 tranny will not last as long as a 400 under decent power. My tranny was over the $3k mark and I still plan on rebuilds every winter.

got a friend of mine that ran a rossler th350 behind a 870rwhp nitrous motor......been in the car for 3 years now no problems.....like i said a "well" built one will.........of course there are alot of other variables in play....weight, launch rpm, driving style, so on a so forth..............not tyring to contradict just stating my experience ......everybody told me i was nuts beating on a 4l60e in my car at my speed yet they are all sitting there looking as this trans is going on 5 years now behind this motor and ive never had an issue with it......

Some people get lucky

I much prefer a TH400 in anything over 3000lbs and 650-700hp

depends on the application as well, car that sees alot of street miles & abuse vs a car that only makes 1/4 mile passes.
