    Stock specs for your cam were approxiamately; .368 int valve lift and .381 exh lift. Duration was around .266 int and .244 exh. Old school, so you can have a little leeway with today's manufacturers. Stick with Comp, Crane, Crower and/or which ever you feel good with. .425-.440 lift on intake. Try to bump the exh to .435-.450. keep total duration to about 272 and not much more. Watch the .050 duration numbers, they can get a little rumpy and I suggest with your set up, 220-225 on the .050 part of the cam card.

    What if the "Hokey Pokey" is what it's really all about?
