Here's a summary of what I have done so far.
The engine build was handled by Second Street Speed, Perkasie, PA. My thanks to Lon Moyer and Bill Hunsberger. And a big "THANK YOU" to George Baxter for helping me all along the way!
My car was purchased new in August 1994, from Thorsen Buick/Pontiac/GMC in Pasadena, CA. It came equipped with the T-56 6-speed manual trans, and was eventually upgraded to include a McLeod Street Twin clutch. All of that has been replaced by a TH-400 3-speed automatic with a Gear Vendors 0.78 overdrive unit.
