I'm upgrading my 89 Dakota shelby. I have already put in a2007 charger complete independent rear suspension. Updated the front brakes to 14 in with 18 in rims. Its time to replace the 280k mile 318. ( very difficult to get the proper ecm).
I have purchased a 2008 5.7 truck motor w/engine only harness, a seperate truck ecm , also 2008. I was going to use the current transmission (42rh) which I rebuilt . After pricing out the belcrank setup for my current transmission, it's not much more expensive to opt for the 545 transmission.
I will have the ecm upgrade. I have ordered the front mounts
? 1 o2 sensors or not
?2. What would I need to make my own harness (I have good skills and plenty of time )
Any suggestions. Jerry
