904 vs 727?

If you are never going to race it, and still use it for a truck to pull or haul things, no need for anything but the 727. IF the truck is going to be somewhat of a "street rod" and not be used for a truck at all, then you have something to think about. This is what I'll say on 727 vs 904:

• Factory stock, 727 is stronger hands down.
• 904's are way stronger than you give them credit for.... mine is stock and has gone 13's and now 12.9's with no gears to help out (2.45's - 3.23's) and still shifts great after 5 years
• 904's can be built to take big HP, and it's proven every weekend on the track!
• 904's are smaller, lighter, and faster than 727's
• converter availability is widely at your finger tips for both tranny's
• 904 is considered an upgrade due to the advantages I listed above.
• 727 is a great transmission as well, and can be built for Big HP as well.
