what solid cam is equivalent to a hyd 268 ?

I am a big fan of the Comp 270S cam. My low compression 318 has plenty of bottom end and awesome midrange. It's 224*@.050", works fine with Comp 901 single (drop-in) springs and 273 rockers/pushrods. A little lopey at idle, but no bogs or flat spots with a 3.55 gear and 833 O/D trans, even lugging 4th gear around town. You can vary the lash from .014/.016" (hot, I&E) to .028/.030" to tune it in to a 273 or even a 360. I use .020/.022" usually on my 'teen.
