William Panouses - '68 Camaro 'Evade'

	It all started back in 2008 when I started my list of requirements to do the LS-Conversion, for Project “Evade” 68-Camaro reading several articles on Pro-touring and Lateral-g I decided to go with Keisler Engineering complete 1967-69 Camaro/Firebird 5-Speed PerfectFit Tremec Kit-TKO600, I contacted Gene Charsha with Keisler Engineering Gene was able to hook us up! with “Evades” LS-2 motor plant Producing over 500HP we need it to be Bullet proof so Gene suggested their 5-Speed PerfectFit Tremic Kit-TKO600 along with Lakewood bell housing for LS motor and Hydraulic clutch actuator kit and all the goodies that comes complete. During the build with several e-mail’s and phone calls back and forth with Gene installing the Keisler Engineering  TKO-600 was a breeze! After the dyno we dialed it in @ 432hp @ the rear wheels! We debuted the car in Columbus Goodguys show 2009 and when I got in and drove “Evade” for the first time in Autocross @ the Goodguys show it was a blast banging through the gears! And even now driving on the Highways in Florida is Awesome! They are by far the best to deal with in customer satisfaction! Another excellent high quality craftsmanship company recommended! Many Thanks to Gene Charsha, and the entire Staff at Keisler Engineering!  You people are the best!!!!

Todd Chynoweth - '67 Firebird

I thought I would share my 1967 Firebird convertible with you, I have driven the car for two summers with the Tremec TKO 500.  I purchased the PerfectFit kit and installed it myself with no problems.  I must say it is the best upgrade that I have made to the car.  The car is much more enjoyable to drive on the highway and the fuel economy is greatly improved. Thank you, Todd Chynoweth WI
