I will try and keep the the truck timing cover and see how it does for hood clearance with the alternator when I test fit it. Worst case I'll get the Holley one.
The Holley FEAD setup is cool but too expensive for my blood. And (I think) the only time it would be really useful is if you wanted to run AC. Cost wise, I think a car TC cover would work fine, minus a notch to the frame rail flange for the alternator. You can run the car TC cover without the AC compressor, just takes a shorter belt.
I have a 2010 Ram PCM I am going to run. I have a PCM out of an '09 Challenger as well that I was going to run but best I can tell the car 5.7 PCM's can't work the SRV and I want that integrated. I have a couple of engine harnesses, the one I plan to use is from an '08 Charger SRT8 but it will need the VVT and SRV wires added plus I will need to verify the rest of the pins match my PCM.
Sounds good on the cam. That was my plan, to just do the 6.4 non-mds cam, tti engine mounts/headers and the 6.4 intake for the 5.7 mods. From my research that seems to be the most practical for easy hp mods.
It's what I wanted to do to my '15 Challenger R/T, 6.4 intake/cam/exhaust. And I figured when since I sold that car and was doing a 5.7 into a Duster, why not do the same plan for the most part. So I have a car 6.4 intake and cam plus Holley swap headers. I figure if it only get's me to 425 crank HP, in a lighter car it should be as fun as a Scat Pack.
