I am an avid fan of the 300. There are alot of upgrades you can do, check out this site under the I6 forum and www.fordsix.com Those guys are great help and can help you produce a hard hauling, dependable ride. Love the 390's but I am thinking economy

I'd rebuild the 300. It's a fine engine and pretty bulletproof if you're responsible with it and do the rebuild right.
C6 isn't overdrive, so you'll only have 3 speeds and with a 390 that's not exactly an economy rig. The 390 would probably give you more scoot top end but it surely weighs a ton more. You'd probably have to upgrade the front suspension with F-250+ HD parts to carry the extra load up front.

Remember, FTE is a business and you don't go moving your customers to a competitor.

I look at cubes per hole, and well the 300 divided by 6 equal 50 cubes per hole and 390 diveded by 8 equal 48.75.
