Installing J.W Ultra-Bell sfi bellhousing on my TH400

[@jakestree1892]

You can pull the pump off and see if the case has the extra 2 holes for the pump. Sometimes they do and only use the 6 just flip the pump body over and you can see where they are supposed to be drilled all the way thru

[@johnalarcon5006]

I cut both a TH 400 and a TH 350 off it was easy but its best to cut a little at a time when you get close to the actual measurement, then test fit your ultra bell and adjust, both of mine came out beautiful , if anyone cuts to much as long as it doesn't affect performance no big deal because you can always use a heavy duty silver or grey caulking for cosmetic appearances once your bell is attached to your transmission and pump!

i just started watching, as I want the info on the 2 extra bolt holes. but that scribed part isnt on stock trans, JW must have done that when they built it originally. And one of my trans's the builder did the other 2 bolts. I need to get the one i am doing now the other 2 as 4 digit whp probably wants it haha. you did a great job describing things, I did mine all with the cut off wheel of grinder. 2 cuts and i have plenty of clearances. those 3 tabs also got me at first. but, since i already have one trans with the bell installed, i had a reference to constantly look at, and i did a fair bit of that.

[@Turbo8secondz28]

Thanks! As far as the 2 extra holes you mention I think you mean the mounting holes on the pump? So I get this question a lot and there are 2 types of pumps 6 bolt and 8 bolt and I can tell you this that those have no reflect to hp the bell housing holds that trans to the engine and the mount in the rear holds it down And center. Power is transferred through the Torque converter and through the shaft to the hub and clutches and then to the output shaft it’s NOT putting what some think is tons of twist or pressure on those mounting bolts.

Thanks for the video I have the same transmission but it’s a 3speed reverse valve body and I have to order the ultra bell housing

[@Turbo8secondz28]

No problem ! There wasn’t not one video on KZbin for this when I made mine but now there’s a few and some have perfected it for sure

Putting th400 in my 800wheel street car 11 5.0. I am done with manuals. This will be my daily driver 9sec street car. Th400 is so fcking badass and practically unbeatable off the line. I already have one in my 700hp 68 mustang street car and its crazy fast. Th400 is awesome transmission for speed and fun.

[@mikejessmax]

Did the same with mine, zip saw disc for your grinder. Watch your pan rails too.

Cool,mine look like cast marks at the cut spot.ill check my other 2

I hope it does! Will make it easier for sure

Im putting an lt1 out of my 94 caprice wagon in a fox body im buying. The motor is free so im using it. Im planning on using a th400 hopefully everything fits. I really like your vid. A lot of useful info

[@nigelwilliams8191]

Good work there man, I was quite impressed with the sawzall on that ally housing, I am researching bellhousing modifications as I am investigating manual gearboxes and clutch assemblies but your video was good to see.

[@Turbo8secondz28]

Nigel Williams thanks! I made it a year before I actually posted I wish I had a camera guy I could have done better but it’s easier then I thought it would be

[@nigelwilliams8191]

@@Turbo8secondz28 Tripods are a great way of setting the camera up so you can work free and it gives you an easier time of showing what you want us to pay attention to. I'm quite used to working alone and not worrying about time, a camera guy would be great but I couldn't justify keeping a buddy tied up at the shop all day.

Nigel Williams ya I need one my wife has one for her live videos she does lol I should take it on a Saturday and do some vids with the car lol

I used a zip saw disc on my grinder. Just gotta be extremely careful, cover everything and watch that damn pan rail on the bottom.

Man that was a great video thanks 👍

[@kevinc3925]

Stock Chevy bell cases are getting harder to find. If you're going to cut a bell off, cut up a BOP case. Pre '76 BOP cases are stronger and use all of the pump bolts.

[@josephhettiger2711]

Structurally it's ok where you cut off too much. How did you determine that.

[@Turbo8secondz28]

For me, I went and did a stage five upgrade on the transmission with Fti and they were OK with it and so far I have done trans brake launches with 1200 hp and it hasn’t broken yet.

[@Taterhead3e]

What part number was the bell housing you use,,was it for stock mounts and depth ,,,also in one of your other vids you had a red front pump shaft plastic cover,, where did you get it and what’s the part number Any help would be greatly appreciated Big ole taterhead

[@Turbo8secondz28]

J.W. Performance Ultra-Bell Bellhousings 92451 Now understand this is for a small block Chevy and th400… All depends on what motor you are using and also what transmission th400/350? Or is it for a ls or ford or dodge?? That all makes a difference on what part number. The red plastic cover I actuall got when I had the transmission built by Fti converters in Florida and you can find them on amazon. Google Universal Transmission Plug Stop-Off

[@Taterhead3e]

It’s a th350 and I also have a Jw 400,,thinking of modifying also what starter do you use,, I have a skip white 434 the starter seems to turn on the slow side

[@Turbo8secondz28]

@@Taterhead3e then that part number will work for you and you can get from summit racing.

[@mikeroberts3660]

so did you have any issue ensuring the bell housing was square on the mating surface to the motor, with the high and low spots of the cut and tight and loose gaps ?

[@Turbo8secondz28]

Negative because as long as the bell housing is bolted up to the pump flush the distance from there to the meeting surface should be perfect! now if you don’t take enough material and try bolting to the pump and it’s not flush, the. There will be an issue. Basically there should be a slight gap between the bell housing and the area where you cut the factory bell housing if you get me? Not much, use a feeler gauge.

[@johnsimmons8456]

I thought an adapter has to be used and the pump machined to the adapter to fit the bell housing on properly?

[@Turbo8secondz28]

What’s your combo? As far as my application sbc,ls1,lt1 this is all you need

[@warrenwatts5313]

Bub..you should have gotten a 7 bolt or 8 bolt case. Also..you could have drilled and tapped one more bolt anyways, however you would have to do this prior to installation of the front pump.

[@Turbo8secondz28]

Warren Watts Just to let you know th400 cases are the same specs now the pump is what’s different you could go out and buy a different pump that would be the better thing to do than to drill and tap but not needed I’ve done five of these are ready and also brought my transmission to FTI did level five upgrade now and I’m pushing 985 rwhp though it so no issues And I trans break launch 5k the power is transferred through the shafts not the bell housing

[@warrenwatts5313]

@@Turbo8secondz28 , wrong...8 bolt cases are available bub

[@Turbo8secondz28]

Warren Watts the pump is the difference between them the case is the same!! I am right ftiperformance.com/TH400-high-Volume-Pump-6-Bolt-8-Bolt-F4045X.htm

[@nyertsenginetransmission3861]

Cases are different you can run a 8 bolt pump in any case but if the case doesn't have the other 2 bolt holes defeats the purpose. Having a 8 bolt case is recommended not saying this won't work.

[@johnalarcon5006]

They say there are pros and cons to either a 6 or 8 bolt pump but im with you , i have a TH400 AND TH350 and both of them are 8 bolt pumps, im from the school of more is better and stronger!!!!!!!!!

[@weshillsberry6275]

If u remove the pump the stator side "backside" of pump usually has the 8 bolt pattern already the front half of the pump usually has 6 so u simple drill the front half of tye pump to match the stator side and u will have all 8 bolts as intended even with a 6 bolt pump design
