727 with gear vendors overdrive unit
Attached is a picture of a 727 we built last weekend with a gear vendors overdrive unit. It is going in a 1970 Challenger (beautiful car) behind a W9 small block. Pure street car but should make a lot of power. The 727 has a good bit of upgrades. All the parts were supplied by A&A Transmission. I wish I took more photos but when we are working, we are often focused on completing the job and always forget about photos.
The 727 has the following upgrades:
Hardened wide lug pump gears with calico coating
Billet steel big piston front drum (high gear drum) with 5 red clutches and kolene steels
Solid kevlar kickdown band (2nd gear band) with raybestos lining, grooves, and 2.2" wide opposed to the stock 2" wide band
Billet aluminum forward drum piston .875" tall with the later model bellvue spring
4 red clutches and kolene steels in the rear drum (forward gears drum)
Heavy duty band strut
Billet steel 4.2 second gear lever
Accumulator blocker rod
Billet aluminum solid low/reverse servo
Solid kevlar low/reverse band, with grooves
Billet steel 3 pinion front planetary with annulus gear machined for torrington bearings
6 bolt 16 element bolt in ultimate sprag
Rear roller support
Deep cast aluminum pan with billet filter extension, dacron filter, and reusable pan gasket
Forward manual valve body with low band apply and high pressure reverse circuit eliminated
Teflon sealing rings
