408 stroker cam recommendations

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.
Bingo, winner!
Keep compression low. 9.0-1 is excellent.
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.
Ahhhhhh yes, the early days! Oh those early days being in a daze. Wasn’t it great when that slip cams in?!?! It doesn’t take much.
1.6 Rockers & solid roller lifter are a must. You need to squeeze that last 1/10 of horse power out of that @ 7400 RPM.
Your so not helping....
But most of know your joking.

A friend recently ran a 408 with the comp 268 cam crappy x heads and manifolds tq carb, poor exhaust in a convertible Dart. With 3.91 gears knocking on 12s in the quarter.

Bingo, exactly, run what ya got.
