Opinions?

[KiltedBanshees93GT]

Ok, as the situation stands, my 66 is in need of a new mill, and under ideal circumstances I would want to drop in a 408 stroker witha t-5/tko conversion. Unfortunatly right now, I cant do that
Anyway, heres what I want opinions on:
I'm thinking about going for a 302 block,unknown year (still planning after all) stroked out to 347, using the pro power kit (anyone have it? Opinions?), with home ported 351 heads, the Shelby high rise intake and 600 cfm holley and hooker long tubes I already have, and keeping the c-4, (at least until I could get ahold of a built AOD)
I'm looking for mainly street performance, lots of grunt on the low-mid range, without wimping out higher.
What kind of cam would be best for this setup? I've been considering going in for a custom grind. Roller or non roller (affects block choice, but if I can, I want a roller block, I like low maintenance), will it make decent power? what am I missing?
Sorry for the vagueness, but I'm still in the planning stage, and your feedback will help me plan out what i'm going to go for.
