th400

[ChevyKiD_69]

ok guys iam geting a th400 and was wondering if the stock tranny mount will work or not or will i have to modify it? nick

The mount is in a different place front to back. As long as you have rubber the mount with the bigger slotted holes it will fit on the trans. Most people don\'t like the 400 in S10\'s as they are much larger, and can cause fitment trouble.

I\'m running a TH400 and don\'t have any fitment problems. You\'ll have to move the crossmember, but that\'s about it.

[ChevyKiD_69]

do you know about how far will i have to move it. nick

[ChevyKiD_69]

and not only that if you are going to run around 425 horse. would you get a th350 or keep the th400. nick

A 350 trans takes less power to operate. Properly built---- a 350 will take those horses, no problem

[ChevyKiD_69]

ok the only problem is that i ghot a 350 but it needs rebuilt and the 400 does not. thats the reason i asked. i might trade the 400 off for the 350. nick

[adh383]

since u got the 400- go ahead and use it------ get 350 ready in the mean time

[ChevyKiD_69]

well i was thinking that to but moving now and what not you all know what iam talking about. but i was thinking of the building the 350 up alot. not sure of what i want to do to it but build the nuts out of it. not only that just wondering about how far do i have to move the crossmember up? if any one knows or is it a thing that it a trial by error. ok thanks again for the replies. anymore suggestions is app. nick

[adh383]

Its trial and error---- set the engine where you need it - get everything else to clear--headers manifolds etc----- then place your crossmember where u need it. Idealy-- engine needs to set as far back as it can and still have room to pull distributor--- and or cap.

[ChevyKiD_69]

ok that makes sence. i do appreciate the help. iam actually buying a th350 works great and so forth. so iam still going to buuy the 400 but iam probly get the 350 on the 10th. again i just found out about the 350 about anhour ago. nick

There is a TD X member at summit that puts the TH400 into a 2WD S10. The TH400 will be the last transmission you will need. The TH350 has to be built up pretty stout to not brake if you horse around. The TH350 cannot take shifting into 2nd in a burnout when you are walking out of the waterbox. I had a TH350 and the stock 10 bolt and when they both broke, then I swapped toaTH400 and a ford 9\". My ETS were around 0.2S worse. If you give me the number off of the TH400 passenger side small metal plate, then I can tell you what it came out of.

[ChevyKiD_69]

well i just found out the 350 was already sold to someone else so back to the 400. nick
