David Kawallek's 1981 TA Street Car

David bought a 535 assembled shortblock from Butler Performance (Dave likes to do some of his own engine work but wanted us to do the shortblock blueprint and assembly). He also bought a set of our CNC Wideport Edel. heads, ported Victor Intake and all other parts to finish the top end. David received everything he needed for a complete 535 Engine in one crate from Butler Performance, including ignition, valve covers, Evac Pump kit, etc. Below is a spec sheet and letter Dave sent to us:

David writes: Car is driven occasionally just for fun- at normal cruising the car seems like a real pussy cat. The exhaust is relatively quiet and with the Drag Radials it really handles quite well. The car rarely ever exceeds 180 degrees while cruising around, even in 95 plus degree heat. I do drive the car to the track every time and me and my Mopar buddy lay claim that we are the fastest street driven cars that are naturally aspirated that race at our local track. That says a lot about the two most unsuspecting cars that are not either a Chevy or a Ford, and when people look under the hood to see a Pontiac engine in the bay after laying down a fast pass is just priceless!! Just the few passes I have made this year with the new engine have just totally surpassed my expectations. I thought I would have to change the converter and gear and really work over the suspension to get it to run a nine second pass. I do plan to change these things in the future just to see how quick I can get this car to run but for now I am very pleased. I have been purchasing parts from the Butlers for many, many years and have always been satisfied with the products and the service. The attention I received and advise on my latest project was no different, David is probably tired of me calling every other week just to keep him updated on how the car is doing. Butler Performance, thank you for all your help over the years and being someone a person could count on when it comes to parts or performance help and advice. Thank you, David Kawallek
