64 valiant wagon-5.7 hemi

the 03 truck motors had valve spring problems, so knowing that if you get one swap them out for 16 6.1 exhaust springs ($40-$60 at the dealer)and you will be fine. allthough tuning is really limited for the stock computer. the only advantage i see is there is no EGR.

the 04 and 05 were the same but if you want to use a truck computer get the 05 because then you get better tuning options. allthough unless your keeping the factory ram trans, it does not matter for tuning as both have great programmers for the motor stuff, (the 04's have no trans control and the 05's do)

the 06-08 have MDS, witch will not be functional unless you go with a factory computer. but it is easy to swap out the lifters and not worry about mds again. the factory computers have full tunability to them with an aftermarket programmer.

if you want to talk about it let me know i have geen modding the modern hemi since 05 and average a cam/ head swap a month i know the motors really well. if i dont know something i know people who do. I am also an installer for inertia motorsports.
