So it's got a 3.08 diff in it then Might be a bit stiff for the old 6 cylinder with 4 speed auto as it will take about 1000 rpm off it in top gear & it will be constantly changing from 3rd to top A 3.45 diff would be better

I have a vn t700 on the 2fluffy3 with an adaptor plate think it came from Castelmain rod shop. Needs to be a 5 liter auto because the v6 belhousing is too small. The vn t700 has the mechanical overdrive and locking converter and kickdown cable so you can hold it in gears. Best mod ever done but just be careful on the free way as it tends to hit the 110 and 120 a bit easier than it used too.
No matter what condition a beddy crusing down the road will always get a long hard stare

mate, you need an adaptor plate.  Only problem is that a T700 behind the inline 6 still means that you have to cut the floor to fit it. 
I've got a spare in T700 in the shed if anyone wants it.

Neil (Willo),

Skippy's is a 253 bent 8. Therefore the question is.... what difference is there in the tranny housing bolt pattern between a 253 and a post VN V8 T700.  ???

Sorry if I stole anybody's thunder.  ;D  ;D  ;D
