what do you guys recommend me doing to increase my hp/trq while my engine is dismantle at this point. keep in mind i gotta still meet california smog rules. i heard that i can bore out my block for larger pistons and as long as i dont touch the crans ill be okay with the carb rules, i guess i could look into carb legal crans too. just want to know what kinda of things are i can go to guys

Actually, YOU need to do some research. Don't mean to be rude but you are wrong Junior.

Compression is based on the size of the combustion chamber with the piston at the bottom of it's cycle (Max chamber size) vs size of the chamber with the piston at the top of it's cycle (min chamber size).

So if you increase the bore & keep the min chamber size the same with bigger pistons, you will increase your compression. You are right in that you can also just change the shape of your piston heads to only reduce the min size of the chamber, but that is not the only way to do it.

Heres a good link that shows you how to calculate ur compression ratio. http://e30m3performance.com/myths/more_myt.../comp_ratio.htm
