That cam is so close to what he already has with the xe268h, why have the kid spend extra cash on a whole new camshaft? For an 18 yr old kid, I'd just use what he's got- stock heads, 650 dp, xe268h cam. Keep compression in the low-mid 9's and that thing will roast the tires at will.
This reminds me of when I was a sr. in high school 18 yrs ago. My dad and I built a similar 408 with stock 360 heads that I had gasket matched by hand with a rat tail file, a 1850 holley, stock converter, etc. The thing was completely mismatched with random parts I already had, could get for free, or close to it. Still ran 12.70's with that *****. And for an 18 yr old kid, you couldn't knock the smile off my face if you tried.
