isn't a sprintex a screw type of supercharger ? if so it will be more efficient than the eaton ,and make more bhp per lb of boost.

Shhh.... I want those for myself eg..

And yes you are right about the sprintex being a screw type.

The blower won't make it any higher than it already is. Maybe even a tad lower. New gearbox and bellhousing has been delivered at my machinist so should be able to level the engine and gearbox better once that goes in.
I'm looking for a Eaton M90 from a early Thunderbird SC. This should give me the same performance as the Sprintex. It will draw mixture through a large Weber or Dellorto. No intercooling so will need to keep the boost at or below 9 psi.
Sounds cool sorry I have not had a chance to measure the items you wanted measured its been manic here with work the new company is eating into play time a little to much but that will change in time I hopeI'm looking for a Eaton M90 from a early Thunderbird SC.

So the supercharger plans are firmly placed on the shelf and the gearbox swap is well under way.
I've removed the old Zodiac(?) gearbox and started measuring up the differences between this and the new (used) T5 that came out of a Chimaera or Groffith 500. I've adapted the bellhousing to the T5 box and it has then ended up being only 40mm longer than the old box. In addition the new box is some 30mm lower than the old aiding fitment. The gearbox mount is 105mm further back so I need to make an offset adapter mount. Luckily the input shaft diameter is 15mm on both boxes!
The shifter will move 85mm forward which is really welcome. Since the prop yoke was 45mm clear of the old box I might get away with changing the yoke for one that fits the new box. However the prop is all wrong since te U-jpints haven't been welded on 90 degrees out of phase. This could possibly explain the vibrations I have had during acceleration and engien braking.

What bellhousing did you use? Also how are you going to drive the speedo? Afaik if it's like my t5 there is a blank in the speedo drive hole (i think the Griff speedo was sensor driven from the diff) and there is worm gear on the tailshaft but i have failed miserably to track down a drive!! Any suggestions gratefully received.

Bellhousing is a stock Borg Warner 35 Auto (often found behind these Daimler engines) with an adapter plate sandwiched in between it and the T5.I have been looking for a while for a speedo drive to fit the 1-1/16" hole. My current thinking is to drill the blanking plug to take a TH350 speedo drive adapter and the TH350 drive gear. I've bought an adapter, but I am unsure if there is anything that will hold the drive gear from being pulled into the tail housing when the rotation of the worm gear pulls the drive gear inwards.

No it is a bronze bushing
It needs to run with a needle bearing..Taking the old bush out is often fun but best way is to inject grease behind bush then use a turned shaft which is a close fit in the bush. Hit the end of the shaft with a hammer and the grease will usually push the bush out from the rear.

Why doesn't a bronze bushing suffice?Taking the old bush out is often fun but best way is to inject grease behind bush then use a turned shaft which is a close fit in the bush. Hit the end of the shaft with a hammer and the grease will usually push the bush out from the rear.
