looking into swaping out my m6 to got with an auto....making 500to the ground on motor and i will be going with 2 stage o fn2o when i go auto totaling 300more hp

 

Get a 400. Places like BMR make everything you will need to bolt it right in.

 

Th400 for sure, 350's can be built to handle that power, but if you're plannign on making 800 hp on the bottle, then I'd go th400, the larger internal parts will take teh hit of nos better. If you're gonna do it, do it once and don't regret the decision.

 

Don't even collect when you go past the 350 and get the 400! Do a lot of research, there is a lot of good folks building them for good prices.

 

probly go with a rossler th-400 with a trans brake.....1400$ is a very good price..... also looking at the yank th-400 with the LS1 bellhousing i like that alot

 

Personally I picked up a hughes TH400 with a rmvb and brake... I am confident that it will hold up to what plan to throw at it.

 

whats the price tag on it

 

Give eastside a call, they are a hughes dealer and can tell you exactly... I bought it with a converter and a driveshaft, so I don't know exactly. But Sean @ eastside could tell you. Same setup that they had in the black car last year that went 8.90... so I think it's o.k.

 

where are you seeing this? i looked on Yanks site and cant find it

 

You don't really need that yank bellhousing, that's a big gimmick. The regular th400 housing will attach with 5 bolts, that's enough. I know of 8 second ls1 cars that are attached with the 5 bolts thru the standard housing and have no problems.... don't believe everything you read.

 

oh, ok i was just wondering if that one was easier and such. but yeah i guess i could live with 2 extra holes anyways
