I have a 99 Dakota 4x4 currently with the original 5.2...I'm planning on installig a 5.7 hemi and have a a few questions....I also have my complete 2000 Dakota 4x4 with 4.7 as a parts truck as well....My main questions are.

1-which trans is best to use the 46RE currently in the 99 Dak or am I better to use the 45rfe out of the 2000 Dakota and then use the engine harness from the 4.7 as well?I'm thinking the 45rfe with no kickdown cable to worry about and seeing as it was used behind the 5.7 anyway would make life easier or is there a benefit to using a 46RE?

2-Is the stock trans crossmember etc retained in the stock position when installing a hemi using the aftermarket Holley conversion mounts?

3-Which year hemi is best?Can I run a newer eagle head or MDS engine and computer in my 99 truck?

This truck is in great shape and my daily driver...Not looking to build anything super radical just hoping to get some better fuel economy and the added performance is a bonus...So once I narrow down what engine,trans I'm going to use i can start accumulating the parts for the swap...I see the engine mounts and now Milodon 4WD oil pan and pickup are available so now is as good a time as any..

I'd like to stay with as many factory parts as necessary regarding the ECM and such just reflash it as I already have a SCT Tuner and trying to keep the costs reasonable if possible.

Any info is much appreciated,thanks... :)
