4L80E dual feed


Ain’t no feeling like Oldsmobling!

Greetings. I’m building a 4L80E for a buddies 66 Cutlass/455 engine. I have ordered a CK Perfomance accumulator body delete plate, my question is do I need to do anything to dual feed besides omit the center seal in the drum, omit the sealing ring on the center support and block the reverse feed next to the center support bolt? Is it the same process as a 400, or added steps? Thanks
