This is a project I've been collecting parts for, but it's becoming clear that I won't get to it anytime soon. My plan was to make a 427 Yenko/COPO 'tribute' car and sell it at a very high dollar value - possibly through a national auction house. The only way to get a 427 in a 1969 Chevelle was to order it directly from the factory using their Central Office Production Order system. Of those COPO cars, some went to Yenko Chevrolet to be treated with graphics and sold through their dealership. All Yenko's were based on the COPO 427 engine option, so that's what I was going for. They are very distinguishable with their graphics package, while a 'normal' COPO was intended to be a sleeper. If you're building the car, then you can choose how much attention you want to bring to your car.
LOTS of people have 396's, but very few have a 427 in them. This is a L72 big block 427 which has a stamping of T0512MN on it. That decodes to a 4-Bolt High-Performance 'MN Block' 427ci / 425hp engine being built in the Tonawanda, NY plant on May 12, 1969. The engine was built and dyno'd locally and is ready to drop in. A stack of docs comes with the engine that has pictures and notes on the various components.
The transmission I was going to pair with it is a Muncie M20 4-Speed manual. If you'd rather go with an automatic, then I can keep the M20. Make me an offer and we'll talk.
For a rear end, a 9" Ford rear end is being hung by a custom 4-link and suspended with coil springs. IDK the ratio though - I'll have to check it the next time I've got it in the air.
As for the body, everything was taken down to bare metal, the cancerous rust was cut out, and new patches have been welded-in. The car should be ready for bodywork and paint, then drop in the drivetrain and interior - DONE! It sounds so easy...
Please give me a call or shoot me a text if you have any questions.
