I agree. I checked two springs and they do coil bind lower than what the Manley catalog says but there isn't 0.060 left with checking springs. I need to order pushrods before I can check with the actual springs. I'm not anticipating a lot of deflection with the T&D shaft setup and 7/16 dual taper pushrods though.

My plan B is to increase the installed height a small amount and just run slightly less seat pressure. We'll make a few soft pulls on the dyno to see if everything is happy. If not, we'll go to plan C which would be new springs. I'm sure I can find another home for the 221443 springs since they are fairly common in the dirt track motors that we build.
