would have been interesting for My Dads Leyland V8 in transit van.. but he never would have spent $4000 odd. (modified his bell housing to accept a $150 used C10) 

 

The clutch-pack size/diameter will always be the limiting factor, but...

 

among other things, to up their power handling -

use the BW51 3bolt rear servo assy, (either in a BW51 case, or modify an earlier case)

fit the wider bands,

 

Fit a lighter check valve spring to the front servo, to allow faster apply/release,

 

fit heavier springs in the primary/secondary regulator valves to up the line/clamping pressure,

and if you're really keen, reinforce the case around the bell-housing attachment area.

 

Plus use the earlier Ford F-type fluid, as it should increase the friction/clamping ability of the clutches.

 

Merry Christmas 🎅
