I had the priviledge of driving John Lingenfelter's old A/ED transformed into a B/ED in 1999. John had some early Pro Stock Truck wedge engines that he wanted to sell along with the dragster, so we got together with some of my parts and ran them for four races in that summer. Prior to going to the Bowling Green points meet, John decided to put titanium valve springs on this engine. He told me to keep an eye on them because they were only good for twelve runs and these had eight runs on them already from one of the then, current Pro Stock truck motors. He also told me that they were $150.00 a piece. After the 2nd qualifing pass, the car lost 5 MPH, and as it turned out, it did have a broken intake spring, so he told me to not take a chance and change all of them and it would be good thru this race and Indy.

This was way to expensive for my pocket book and I really don't know if I saw anything in them. I would say today's springs are probably a lot better than those were and obviously, a lot cheaper. We have ran our PAC springs for many-many runs without problems at 10,500 RPM.
