6.1 Hemi into 72 Demon March 2018

So it is yet another cold windy day up here on the Tundra, I have already went out to shop and fired up the heat. Sitting here sipping green tea pondering next steps while shop warms up. I always back read a couple of the previous posts to make sure I am making some kind of both chronological and common sense. Dawned on me perhaps I should elaborate a bit on the topic of plug and play with regard to EFI systems choice. I went with Holley after much consideration. I felt then, and still do, they were the best supported system as I knew I was going to be in the weeds a bit. If I were doing a LS we would be done by now. However doing old Mopar blended with new there is just not a lot of support. Dodge has now come out with the crate program which makes the whole process much easier and pretty straight forward. When I started, that just was not an option. I got a donor drive train from a 2010. Knowing what I know now and with availability of crate that is the low cost option. But I digress, plug and play is the topic. So on one hand yes the ECU plugs into the factory wiring, however that is like trying ****** for first time. You are now addicted! You must now purchase a million subsequent modules and sensors as a result of the Holley components may or may not be compatible with whatever next step is. From oil sensors to O2 the list goes on and on. You need a coil pack, you need a BIM, you need a way to integrate to a dash, nope might as well buy the Holley version and simplify. I can go on and on. Sadly in my opinion Holley is still the best choice out there as Mopar is just not supported in after market like the LS platform. Do I have any regrets? No way! But if I was going to do this again and was starting now the landscape for support sure looks different today than it did a few short years ago. The guys on TV can do one in a week or less!
