360 Magnum Daily Driver (but fun too!!!)

I can understand the merits of the OEM truck set-up only if you are planning on keeping it stock or nearly stock. I.e. very mild cam, headers. If you ever want to get more wild with the combo though, I'd go aftermarket.

Also in terms of reliability and ease of use, there's plenty of solid options out there. Fitech and Holley both make systems that work just fine and are self tuning.
