i was curious to know if i would be worth anything to change out just the pitons on the stock block to obtain a 11.5:1 CR, or if it is not a very solid idea. i have been playing with what to do in the long run, and after exhaust, intake, TA, pullies, heads and cams i am thinking of what to do with the block (no blower in the future) and am not sure i want to spend the cash on a big bore aluminum block, and was thinking this would be cost effective. think so? or bad idea to just change out the pistons for less dish.

Going to a higher compression will help, but I think 11.5 is too high for a street motor. You'd have to pull out a lot of timing to run on premium. 10:1 is good for a street motor. I know the guys with the PI swap are running 10.5:1, so don't flame me on that.
