BTR .660 spring limits As I am buttoning up my build, i have been looking into more and more and came across a lot of guys running the BTR .685 springs and being able to rev the motor higher. I really cant find too much data on the limits of a .660 spring before it falls on its face. At the time of purchase i had in mind this was a good spring to close to 8k rpm if need be. Basically looking for some info before i throw the motor in the car, while its out if i need to change the springs in it. Its a sbe 5.3 lh6 799 heads, manton pushrods, johnson 2116lsr links, btr stage 3 turbo cam, headstuds etc. vsr 92/103. The goal of this car is to push it to its limits. Any input is appreciated.
