I definitely made an improvement in 60 ft. with Calvert Springs
and Bars. I also saved some weight. I use them on all our Stockers
and even my 318 Superstocker and 9 Second bracket Duster..
Also some adjustable front shocks make an improvement over the
Calvert Shocks once you are into the 1.3s or faster and have some
issues.
However, 1.36 is a GOOD number for a high 10 car or even a mid 10 car!
