Larry, save your money on the K-heads. Since I'm changing to the new 505 combo and the 462 will be sitting idle.... why not borrow some round port headers and lets slap my old motor in your car for interest
Now with the small, and tame, 248 solid roller installed it wheezes out at a comfortable 5600 or so rpm and will run a 3750 lb race weight to a easy 11.50 or lower ET. And with a whimpy 9.7 compression it will run on crap gas.
