    I called NWT parts and they were great. The say from the first letter of "C" it is a Cadillac transmission, but it is missing the two (2) digit year code after the dash. The numbers after the dash are the serial number. I have to send them the case housing numbers along with the tail shaft...

    Here are a few updates to my 48 Caddy project. To do things right, the engine needed a complete rebuild including boring the cylinders to clean up some minor rust pits and lots of new parts. I ended up finding a complete 1947 Cadillac flathead that was just pulled from a running and driving...

    I finally got the engine pretty much disassembled. Three of the pistons were stuck; two of them stuck very tight. I ended up damaging the 2 stuck pistons to get them out. The remaining pistons, rings and crank shaft look to be in very good condition. The next step it to remove all of the...

    I pulled the exhaust and intake manifolds off to find that mice tried to start an apartment complex inside of the exhaust chambers inside of the block and really made a mess. I pulled the timing chain and gears off and was able to rotate the cam shaft back and forth slightly. As a result of...

    Just to update this post for future readers, the torque converter is not like today's converters. After using a fork lift to pull the engine and transmission out of the caddy still bolted together, I needed to rotate the transmission around the engine (after the 6 bolts holding the tranny to...

    The Caddy is certainly winning this endeavor. I'll see how much of a problem it will be to pull both the Motor and Tranny as a single unit. I just don't know if I can get enough angle to try remove them as a unit....I don't want to take any from sheet metal (radiator support) off of the car to...

    I'm trying to pull the engine with the torque converter still bolted to the flywheel and leave the tranny in place. I've done this a few times and the snout of the converter usually just pulled out of the transmission pump. I tried for 2 hours tonight to pull the motor but the converter will...

    Agreed!! I have been soaking the engine for 5 weeks with transmission fluid, diesel fluid and acetone. I pulled the oil pan off and everything appears good from below; I pulled the heads and with the exception of a bunch of carbon the top end it looks good also. A 3x3 chunk of wood in each...

    I have a 1948 Cadillac I'm trying to get back on the road. The original flathead has only 50,000 miles, but is it stuck tight and I'm having a tough time getting it to break free. If the motor turns out to be a large paper weight, what are the possibilities of dropping in a Chevy 350 with a...
