Question where can I get heaver Valve springs??? Got cams grinded from web cams and Know I need new springs can you recomend any good place that sells?? also Lift on cam is 386 just shy of having to change system from shim over bucket to shim under.. Any info would help
My springs are from Megacycle (//www.megacyclecams.com). I gained about 2k rpms before valve float. I am running .417" lift cams with stock shims. Megacycle does sell shim underbuckets as well, page 50 in their catalog. BobB has info on other shim/bucket options. I may have the info at home or pm BobB.
