Jim Koopman's 1966 GTO

with a Butler Performance Engine(428 Block). Ported Edel. Heads, custom grind roller cam. Purchased complete turn key engine along with a matching TCI trans and custom torque convertor from Butler Performance in '98, and still running strong.

"Hey Butler Performance,

You guys did this build in 98' its a 428 block with new 4 bolt caps, stroked, bored, Ultradyne roller, Crane ingnition, Hedman Hustlers, its AMAZING, starts on the first crank, I'm so happy with it. I also like the TCI trans and converter you had put together for me. If you all ever need a referral out this way feel free to contact me, I will gladly help out, I am so proud of my car with your awesome build in it. This car was one of my fathers first demonstrators when he bought his first Dealership, Koopman Pontiac Cadillac, GMC, Sheldon Iowa. I was promised the 10th anniversary Trans Am, long story short I got into too much trouble that summer and he sold the Trans Am, and gave me the GTO. It was shot & rusted out, but I was 9 years old, and thrilled, so from ages 9 to15 I put the car back together with salvage yard parts and working nights, (my father died when I turned 13). The car has a ton of sentimental value, & pretty cool history. I had just started to go through it again when I contacted you, and what a motor/trans you all did for me! The body / paint was done out here at the GM Proving grounds just before they let most of the GM guys go. Well here are some photos, I'll let them do the talking. I would be flatered to have it added to your portfolio of great Pontiacs! Say hi to everyone, they were always real nice on the phone whenever I called, and Thank You Again! Best money I have ever spent!

your friend,

Jim Koopman
