What trucks' engines were the "small" bolt pattern used on in the Fords?

I.E. was it a gasser engine or the like? (maybe the 350?)

1988 Model Year F150s and FS Bronco with a 300/4.9L were available with the ZF or M5R2.
The door jamb sticker will have a "Z" under Trans.

I previously saved this information from member Cabell Garbee.
http://www.garbee.net/~cabell/

ZF S5-42 were actually factory equipment in a number of Ford heavy-duty trucks for a few years - they were installed in 2wd and 4wd '87-'95 F250 HD’s, 350’s, and 450’s behind Windsor blocks, 460’s, and diesels. The S5-42 uses an external slave cylinder (same part number as the NV4500 interestingly for the early version, vastly different design (and better retention) on the third version of the MC that was supplied to Ford (get it for very little money at Advance Auto...). Max torque for the S5-42 is 420lb-ft.
The S5-47 was used in the same product range until the introduction of the six speed ZF 6-650. S5-47 uses an internal slave cylinder and has a torque rating of 470lb-ft.

The overall length of the ZF S5-42 in 2wd is 26" from the bellhousing face to the rear output and it is 14.5" tall. 2wd version has a 29-spline, 1.495" diameter output shaft, Spicer yoke on it is ZF part #1307304079 or Ford part #E7TZ089A (local dealer charges about $50.)

If you get a Ford chasis breadvan with a Cummins 4BT or 4BTA with the Ford flywheel adapter, you can bolt a ZF S5-42/47 right up as long as you get the smallblock version...

small blocks like 300-6, 302, and 351W. and I don't think half ton models came with these, they got the M5R2.
The 300 six is generally considered a "big block" six engine. Never seen a ZF in a 1/2 ton myself, but it may have happened.

The ZF was used behind most 5.8 (351W) powered F-250 and larger trucks. The ZF was also a sure bet in F-250's that have the HD dana 50 front axle (D60 style hubs). The most common place you will NOT find a ZF is behind a 5.0 (302) in an F-250. The 302 trucks were gutless turds and needed an extra gear to get rolling. They got the M5R2. The light F-250 with a 4.9 got the M5R2, the HD F-250 with a 4.9 got the ZF.

So, just so i can get this straight, '87 - '95 ZF S5-42, with the 300-6, 302 and the 351W are the trucks that I'm looking for to get a small block tranny bolt pattern, right?

And 96-97 with S5-47 too.
Externally the S5-47 has more casting ribs.

I referred to 97 since it's the last model year for a SBF bell ZF 5 speed.
Model Year 99+ the S5-47M have the modular bellpattern when used behind the 5.4 and 6.8.

Ok, so then anything after 97 will most certainly be the bigger bolt pattern, as I am understanding it now. Or at the very least something that won't fit to the small bellhousing pattern.

BobS and others..... judging by the reference chart.... my transmission (94') should have a electronic speedometer.... I indeed do NOT have one in my transmission... I thought the VSS was located in the rear axle?

1992 and new Ford transmissions and transfer cases DO NOT have any sort of VSS in them. The speedo, cruise and EEC are entirely run off the tone ring in the rear axle.

Any common fixes for this? Considering I'm running the P30 axles (That dont have a VSS) .... I am now left with no 'solution' for generating a speed signal. I know people have said there are driveshaft mounted solutions...but I have yet to find one at all.

I know the close ratio s5-47 was mated to the powerstroke only (No gas engines). Would the closer ratios be better for the 4BT's narrow power band? I am looking to put it in my scout, mostly for a daily driver.

Here's a GM solution. You may be able to do similar................

http://www.jagsthatrun.com/Pages/Parts_S10-Reluctor-Diff.html

Anyone review this and give some feedback? Would this ring fit on a 14 bolt DRW rear end pinion? My knowledge of GM equipment is almost ZERO... (Ford guy by nature) Any thoughts?

EDIT: Is it possible for me to have my transmission case machined to where a speedo plug would be and insert one? is it possible to swap the tailhousing out? Anything? Cheaper the better..but a non-road condition effected solution would be worth more to me. (IE will rain screw up a sensor that is mounted on my driveshaft or rear end pinion with the exposed magnetic pick-up?
