Project Trans Am – Focusing on the Engine

To update on the progress of my project 1981 Trans Am, the Turbo motor has been successfully pulled and I’m now in the process if getting it sold. So if you’re looking for a Pontiac Turbo 301 from a 1981 Trans Am to rebuild or for parts, please contact me!!! I’m going to keep some of the core parts for the Turbo just in case I need them for the other motor.

Pontiac 400 W72 EngineIn late August I acquired a Pontiac 400 V8. It is a Pontiac 400 from a 1977-78 Trans Am with the W72 option. Click here to read details about the motor. What makes this engine special is the heads, which are 6x-4 higher compression. Even though this engine does not have the same compression as some of the older Pontiac 400’s, it should be just right for the desired mixture of performance and economy I’m looking for in a car I can drive on an almost daily basis. The motor included the TH-350 automatic transmission with the original torque converter as well as the original carburetor, which helps out tremendously with the swap.

My initial plan was to just go ahead an use the motor right away in the car. After spending a good month trying to clean the motor and do some light dis-assembly, I came to the conclusion that I really need to take the engine down completely and have a machine shop do their thing to the crank, block and heads. This weekend I plan on taking it apart and taking it to a reputable machine shop known for Pontiac motors to do the valve job and let me know what sort of condition everything is in.

I’m recording video of the process, though I am on the fence if I should release all the work I’m doing as a podcast or not. What do you think, should I post all the video as a podcast? My only reservation is, I’m no automotive mechanic expert and I don’t want folks to watch thinking I am an expert.

I have to thank Mr. Yuhnke for all the help acquiring parts for the motor and Chris Goetz for coming down to helping me with the engine swap and for putting up with going to Greaters for Ice cream, I know it’s hard!
