Previously posted about my six pack motor partially eroding one lobe on a solid lifter cam. Had just gone to a stiffer valve spring on the Eddy heads that I put on it. So now after putting in a Lunati Roller cam, changing the oil and filter 3 times, the motor is running great! Took it to Bandimere last night, and ran a 12.20, 12.18, and a 12.13 all at 113 MPH. Previous best was 12.90 at 105. So the Eddy heads along with the roller cam made a big difference! It revs easily past 6000 before I shift, and pulls real hard. Pretty sure this 69 RR would run low 11s at sea level.
