best the 408 could do was a 10.65@127.6 in 83* weather. 60 was 1.53. just could'nt get the car to 60 any better with shock adjustments.
first pass was 10.66@126.9-1.52 60. went down 2 on the jetting and went 10.69@126.5-1.54 60. went up 1 and went 10.73@126.6-1.59 60 spun. timing went from 32* to 36* and went 10.65@127.6-1.53 60. went up two more on jetting and ran 10.66@127.6. jet changes made little differences and timing got 1 more mph. car went straight so i did'nt touch the cal-trac adjustment. 60'ed better on ss springs with a 1.49 best.
