Hello all,

I'm new to this forum as you can probably tell,
anyway i am in the process of building a 383 stroker for my caprice coupe, the short block is a 4 bolt main, scat crank and rods and speed-pro flat tops, was told with 64cc heads the CR would be 10.2:1 and with 72cc it would be 9.1:1, i will be using a set of of edelbrock performer RPM heads that are 70cc, hoping that would make 9.5:1, can i run the 64cc heads and still use pump gas? i havent bought the heads yet so i can go either way, my next question is about a cam, i was told by comp to use the xe268 that has 224/230 dur@050 .477in .480ex, and the guy who owns the speed shop here says to go with the xe284 that has 240/246 @050 and lift is .507in .510ex, both have 110 lobe seperation, what cam do i go for? this car is not going to be a daily driver but will be driven almost always on the street (weekends, cruises, ect), the car does have PS/PB and A/C and i would like to keep them, would even consider running a vacum canister if need be, i just dont want to get it to the point where i have to work to drive it, but i also want as much power as possible (can i have both?) any sugguestions would be very helpful
