Cast iron A-466 to A-727 conversion Forward Look 56 to 61

Post by RICKYMOPAR »

Converting A-466 to A-727 push button 62 to 65. I performed this conversion many years ago, and are revisiting it now, helping a friend of ours resurrect a non-moving forward look convertible. after pricing front pumps and torque convertors as well as rebuild kits, We decided to up grade to a still serviceable A-727 push button operated transmission. I like this conversion being it works so well and still can push start the vehicle if necessary, and uses a starter that is easy to find.

Known problems in conversion;
Crank shaft length difference and number of flex plate bolts. Finding the 62 E brake tail housing some trucks used this also and later years.

Solutions;
Change out crank shaft with 62 or newer, take your old crank shaft to engine balance provider and have it indexed and match the old balance.
use an adapter kit.

We are using and adapter kit being retaining the long stroke A engine. Hot Heads on the left and R&D Power Engineering right Gold B&M 426 Hemi flex plate. Prefer the on on right for many reasons.


will continue as work progresses.

Sunny today but not warm. Decided I'd better continue this endeavor and not find my human remains on the couch. I found a huge mess of brown shoe polish coating everything and about 1/8 inch deep in transmission pan, and clogged filter screen. Disassembled everything including band servos. Scrapped off all the brown shoe polish I could get to trying, not to ruin my solvent tank. Found rear pump check valve also to be clogged, but the rear pump survived and is still useable. Yes I did spray off the valve body with brake clean before removal. Planning on changing second gear band apply lever to a better ratio, and installing a drain plug in the pan, an inline transmission cooler line filter not just a magnet as well as a Gil Younger shift kit, so we can select the RPM when the transmission shifts.

Continuing E brake repair and cleaning, found pieces to be missing, like adjuster wheel and pivot shaft and bad E brake shoes. Lots of cleaning to finish. More pictures below.
