I bought the car from Jjennings and use the name PaxtonCougar on NECO. This motor does have the adjustable cams. I am trying to find David Z with regards to the motor that he and Jjennings put in the Cougar. According to Jjennings the motor has less than 15,000 miles on it. 10,000 put on the motor by David Z and 5,000 miles while owned by Jjennings. Any help in finding David Z would be appreciated. Thanks.
