I would gear for keeping the RPM below 6800, especially trying to control the valves with 1.6 rockers. My "extreme" flat tappet springs would be 150 seat, 440 open. But that is starting to push things for durability on the lifters. 1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG). Link to 572 B1 - Part 1

Thought i may have been tickling the rev limiter which was set at 7100, i now am thinking that the valves were barely under control at that rpm. not sure, but i know my shift points will be below 6500 this time out. I may have to run 1/8 mile only. Will see. Thanks . http://www.youtube.com/watch?v=aIxaesJ190U http://youtu.be/lCZAaN7fFLg
