Thanks, Mike A114

That 389 was tested several years ago, and it wasn't tested by me, but I was there but can't remember the peak, I do remember the build because I machined it, low drag, well thought out oil system, a lot of detail work, a well designed engine that ran excellent in the customers GTO and still runs great to this day. Its important to note the customer insisted on using the factory 64 heads with the horrible valve angle. You can be sure it wasn't 7500 RPM.
