FYI, this is more for the general forum than a specific respondent.

Ok, at this point the research is inconclusive on some points and definitive on others:

Just capping or unplugging the VVT is an option but it will adjust cam timing randomly. Will NOT normally throw codes on the Motronic 4.3/4.4 but is a performance issue.

Bolting up the 1998 sprocket should work but we may have a cam seal issue.

Best answer is a custom machined hub for the 1999 VVT sprocket (separate from the VVT hub) as the 1999 seal that comes in timing belt kits will fit fine.

All sensors fit.

Intake manifold "should" mate up.

Distributor to cam interface might require a hole drilled for the rotor (I am not understanding this part yet).

I am not just doing this so I do not have to pull a second motor (which is a serious issue) but everything about the 1999 motor screams clean, well cared for. Pulled the exhaust manifold today and the exhaust valves are as clean as the intake, PCV ports are perfect, timing belt was in time and even the motor and tranny mounts were like new (so must have been replaced).
