M78 is Dana, BW78 in E-Series. 4 Pinion = stronger than B-Series 2 Pinion. Also, IRS is different to Live axle in strength. Ford went back to a 2 pinion diff?

Although M78 gears are the ssame as BW78 IIRC. I'll be testing if a 4 Pinion BW78 centre fits an M78 housing in the next few weeks!

They're the same centres no matter what they are called,so an early Dana 78 type is still not as strong as the M86 type no way.

The m86 gears are bigger, i think they're 8 3/4inch in the old money.

AFAIK 78- 7.8" gears, 86 - 8.6" gears. Also, B-Series run a 2 pinion diff, EB2-AU run a 4 pinion

Personally i would stick with the factory engine, Spend the 6500 on a nice turbo, manifold,injectors,pump,computer,headwork,cam etc.... Will make power east and be a weapon 0-100.
