Anybody have any advice on which year motor and trans is best to go with?

for the foreseeable future, stay away from the '09 and up 5.7. There is nothing on the market to operate VCT currently. Aparently, the stock ECU is to complicated/unknown/restricted to run the engine in a retro fit.

The heads are killer:snakeman: though.
