So I have picked my self up yet another body and am planing on swaping the motor out of my damaged TH shell in to the 98 KF shell rather then repair and keep the shell from from my damaged well used TH

The question I have is are there any differences between the 98KF 3.5 and the 00TH 3.5 and they way they hook up or will it be as simple as just unbolting and replacing as I am hoping.

Answered by Mal and may I say thank you very much for all your help Mal

Answer for anyone who may be intrested or looking in the future "hope you dont mind the copy paste Mal"

There really is no difference other than the injector harness on the motor.The KF does not have EGR which the TH does. Simple solution is to remove the upper manifold, change over the injector harness (is only 6 plugs) and then use the KF upper manifold. You dont need to remove the egr pipe from the exhaust, just bolt it back on to the KF upper intake as there is a blanking plate for the EGR anyway.
