Walt Reynolds - '68 Z28 Camaro

I probably should have done this a long time ago but here I go. I am the original owner of a 1968 Z/28 Camaro. It has about 25000 original street miles and over 8000 1/4 mile drag strip passes. It still has original paint and interior except the carpet has been replaced a few times. In 2006 I went on my first Hot Rod Magazine Drag Week. At the time, the car had a Super T10 4-speed and 4:56 gears. It was not very fun to drive 1000 miles at 4000rpms! In 2007 I installed my Keisler T56 and 5:14 gears for Drag Week. The transmission made it so much easier to drive in the highway. 75 mph was about 2200RPMS in 6TH (.50) For this years (2010) Drag Week I changed the rear gears to 5:57 which is the ratio I used back in the 70's. For Drag Week 2010 I had set three goals. Make the whole round trip, lift the front wheels off the gound (pull wheelies), and ET in the 11's. Well I made the first two which isn't too bad. My car is an original 302. It is set up like an NHRA stocker. It is .030 over with a Lunati RL302 stock eliminator cam, Manley Rods, original intake manifold and 4053 (780 CFM) Holley carb and Summers Brothers spool and axles. It launches at 7000 RPM and I power shift @ 7500 RPM. This year David Freiburger of Hot Rod asked me if I would have my car lettered like it was for the 1970 Winternationals and I said yes. Here are some picturesof the car both ways. I want to thank Keisler for the great kit. It was very easy to install and works fantastic. I think I want to check out the new clutchless model!

Robert Kostash - '69 Camaro RS Yenko Pro-Tour

The shop that completed the Pro-Tour project has used Keisler 5 speed and 6 speed kits numerous times...they were keen to do another Keisler TKO600 for my car. I also highlighted the progress through the winter on Pro-Touring.com. The car now drives just super, with the tight shifting Tremec. I just love the overdrive!
