402 Stroker....need piston advice... I have a new GM 6.0L iron block(LQ4), w/a 4.000in forged Eagle crank, LS6 '02 cam, and LS6 heads (65cc) for my Silverado Engine swap. What size piston(s) should I use if I want a daily driver (NA).?

I'd like to know what size dish ( -6cc, -12cc, -29cc, etc...) would work best for the engine (NA) I'm building.....in other words, what size piston would get me in the neighborhood of a 9:1 to 10:1 CR? ...

Thanks for the link and -12cc advice! This helps alot, now I just need the rods and an LS6 intake manifold. I plan to have my machine shop put the lower end (402ci) together...and do the top with my brother in-law(certified mechanic). Bsically swapping new stroker into 2000 Silverado (5.3L)...bolting on external parts to new 6.0L. ...want to get 400+ rwhp with NA...but would like to have FI options later.

GuitsBoy,
Thanks for the feedback, I'm considering low compression CR in case I want to add FI later....just not sure what to do with that. As far as the cam goes, the LS6 02 cam has a .055 lift 218exhaust 204 instake....117.5 LSA, I've read that this cam is probably GM's best designed cam ...my truck is a daily driver so I want some streetably manners....what cam would you suggest?...

Good advise....definitely worth investigating more(thanks)...right now I have just about everything I need except the rods, pistons, intake manifold (and now possible a more aggressive cam). Having never done this before, the anticipation is driving me crazy....I'll probably schedule a week off of work to get this done once I have everything ready...I'll provide updates at a later date. Thanks again.
