Not really worth the hassle to try and swap an L67 into it. You'd have to get some 04+ returnless Supercharged fuel rails (or aftermarket) and a TB adapter to run the gen 3 SC with the drive by wire TB on his car.
Easiest route would be to just swap a whole L32 (supercharged Series III) motor in. Then keep his L26 (N/A Series III) and keep it as a spare, sell it, or build that one up as time/funds permit.
Next easiest would be to topswap with a L32 top end. About as involved as a whole motor swap (having to strip it to a short block and rebuild it back up) and would be much simpler than trying to put the L67 in there.
