SBF transmission input shaft length?

[Ant]

Looking at SBF Lakewood bellhousings they come in two input shaft lengths 6.361" (15-200) and 6.924" (15-202)

Is there one small bock Ford input shaft length? - as when go to order parts like hydraulic throw out bearings it may get complicated!

Info gratefully appreciated.

You planning to use a Toploader, T-10, T-5, or Tremec tranny?

Jerico or G-force five speed!

Ant....many SB trannies are different....I would say the Jerico would even be a little different than a T5....If you look at Lakewood's catalog, you can see which bellhousing fits which tranny.....pretty sure the Jerico & Toploader would be a different length than a T5....or G-Force.

So I guess the answer to your question is that there are a bunch of possibilities there....you will just have to pick your tranny, pick your bellhousing, then go from there....Once you get those two nailed down, you should be able to call anyone and tell them what you got and then they can provide you with whatever parts you need.

Blykins,

Thanks, I have worked out two issues the front shaft is 6.361", so a Lakewood 15-200 should do that! Then its a button clutch with a flexplate between that and the crankshaft, and I think I will use a twin plate Tilton Rally clutch, and hydraulic throw out bearing.

Jerico have received a deposit on a five speed transmission with:

2.772
1.925
1.474
1.204
1.00 on 3.27.1 diff and 25.6" diameter tires

So I am commited to a Jerico but can change ratios if necessary!

[blykins]

That's pretty cool....I have wanted a Jerico...but I'm probably 95% street use....so it's not practical for me.....Always wanted one though!

This should be an easy call.....I would call Tilton since they make bellhousings, hydraulic TOB's, and clutch systems...they should fix you up anything you want. Actually, McLeod would be a good candidate also. You should be able to get the whole deal from them. Keep me posted!

blykins,

I suppose some race transmission manufacturer make their stuff different lengths like G-force on their five speed have a 7.100" front shaft length (I think)

Will keep you posted, by the way I used to drive a Seanz dog box on the street, and the long and the short of it is "dont let anyone else drive the car" and there is no problem!

You can order whichever version input shaft you need from Jerico. When I recently decided to try the Jerico from my 428FE, I tried it "as is" for a mockup in my 302 Mustangs McLeods scattershield (previously run with a T5). The FE length input was too short to either even touch the discs splines, or for the tip to even touch the back of the pilot bearing. The T5 uses a considerably longer input shaft, & obviously, a deeper bellhousing. However, a phone call to Jerico quickly provided the required length input, with the correct Mopar 1 3/16" x 18 spline "Hemi" spline that is needed for my McLeod "soft lok" clutch. Jerico can provide whatever input is needed for most combinations, although thay don`t make an input with the small input Toploader dimensions (1 1/16"x10 spline), at least for the 4 speed Jerico drag race trans.

Rory428,

Thanks for your info, and I have had the McLeod part # to suit the 5 speed Jerico that I am going to get built!

What are you running behind your FE now, if you are going to fit the Jerico to your Mustang.

I have put my Jerico on hold (paid the deposit) but not totally sure of engine choice at the moment, still toying with the idea of an alloy FE, but expensive, and would like to go alloy SBF like the Fontana clevor style block, as my car is going to be mainly road race and street!

Ant, the 428 Fairmont will stay with a Jerico, I plan to just race the Mustang this year, so the Fairmont graciously "donated" it`s Jerico while it takes a year off. Ideally, I would have a Jerico for each car, but at this time, another trans isn`t in the budget at this time. I DO have an older Doug Nash 5 speed race trans I`d like to try in the Mustang, but I`d need to convert it from its current Chevy configuration first.

I know the feeling when it comes to the budget!
