My Black Bitza
Scott:
I'm not super keen on spacers either, but the bellhousing will be aligned on the bearing retainer and I'll loctite the bolts, so there shouldn't be any issues with movement.

How much torque will is the engine making.
( I'm glad I when with a 6 speed magnum less problems and handles more torque )

Scott:
Considering it's a stock 400 with a performer manifold and a set of shorty headers, not a huge amount. Realistically, the gearbox is rated to 600lbft (with a considerable safety margin). The tyres won't hold that much torque on the street anyway. The spacer will put a tiny more amount of stress on the bolts, but not enough to be any worry to anything. The clutch will still be the weak link in the system. So I can't foresee and mechanical danger of using a 3mm spacer.

I used the Bathurst weekend as a good excuse to disappear into the shed and get some stuff done. Luckily I have a borrowed telly in the shed for such occasions.
Also had my No.1 helper on the job.
After making and fitting my bellhousing spacer, putting the hyd. throwout bearing on and adding the lines, I hoisted the box up, then spent 15 or so mins adjusting angles and heights before everything slipped smoothly into place.
I spent more time trying to nudge the crossmember into the right place so I could bolt it to the chassis, and then tightened up the tranny mount bolts. After that I spent some time looking at the angle of the box and thought to myself that can't be sitting right...
I checked with a straight edge and the cross member doesn't look bent, but who knows. I know the engine is sitting a little high, so I'll fix that up and then try measure the angles of the box and diff. I'll throw int he tailshaft as well. Hopefully I can get the angles right by shimming things up and down. Otherwise, the vibrations will be killer.
bfit:
yes it does look to be at the wrong angle .
the engine should be set around 3 deg downwards towards the diff
and the rear of the box must be above the diff input.
you should find your diff will be set vertical at the yoke that goes against all the advice you will read , however I believe that is the factory set up.
Id ne interested to know if you check your diff and find it is set differently
