New project which direction turbo slant six or 360 magnum efi with od

We'll folks I have three months to lay up and decide which direction I go with my newest project car. Either 360 magnum efi and od with 8.8 explorer rear 3.73 gears or slant six with 904 (already have but doesn't run) phista j pipe turbo exhaust flange inter cooler with some upgrades 10-15# boost 2.76 geared 8 3/4. Not a track car. Will have pro touring mods, frame connectors, mini tub, springs relocated, adjustable strut rods, adjustable upper control arms, and a few other suspension upgrades. Reading all I can for the next few months before I make a desicion. Love the turbo sound and feel of the boost and I love the sound and feel of av8 with Efi and OD. Decisions desicion a.
