408 stroker

I'm building a 408 stroker motor I have the block, crank, intake, Eldlebrock heads, pistons, rings, etc. etc. etc.

The heads need mechanical rocker arms/mechanical cam and I need to pick out a good cam. Have you or know anyone who has built a 408 stroker, what did they use? I would like to use roller tipped mech. tappets.

Online Hot(Chevy & Ford)Rod magazine did a 408 build up and they used a crane cams 260/266 lift and they did over 600 horse on the dyno. But that was with W2 heads and a dual quad hi rise intake.

Any advise from someone who has been there?
