LS6 Manifold Swap Part 1!!!
Well here is the proccess in order to take it apart and prep the new manifold to be put on. From a stock LS1 intake manifold to an LS6 intake manifold, EGR Delete, Coolant Pipe Revision etc!
Part one, Start unbolting !
Part Two, take of off fuel rail cover and vaccuum lines and more ...
Part Three, take a break, cause you dont want to break poor ol' oil pressure sending unit!
Part 4, Show off the Z06 intake manifold that you custom painted high gloss 500 degree ceramic paint w/ clear coat and make fun of how the old one looks plain!
Part 5, about to go to sleep and finish this tomorrow!!!!
Ported TB!
Old Manifold!
New Manifold Before!
New Manifold After paint job!

yes thats my LS1 throttle body that I ported myself 
the LS6 has a different set up and wont work with ls1 applications I believe. My TB is now a 78MM bore instead of the stock 75mm

well let me find the specs right quick!
ok here they are
LS1:
Plenum Volume: 5.06 Liters
Runner Length: 262 mm
Runner Volume: .536 Liters
LS6:
Plenum Volume: 5.19 Liters
Runner Length: 262mm
Runner Volume: .541 Liters
so the runners are the same length, over all runner volume is .004 bigger per runner which over all is .032 Liters bigger runner volume
