This is designed to be a drop in kit.
With the 904 you have to have the sleeves pressed into the jugs. With this kit you swap pistons and cams, no need for a shop.

Im waiting for Carlos to do a dyno run and see what this gets.

He estimates 8-10 RWHP.
If stock is 54 bhp / 51 ft lb stock reference #s
904 is 74 bhp / 64 ft lb 904 reference #s (average taken)
865 kit is est to be 63 bhp / ?? ft lb

Huh...I think I just figured out the BB, even with machine shop labor, is a better performance option.

Now I really want to see the dyno #s.
