Speed-density cams

hello,
I was interested into a little more information on the speed-density cams available for us 86 guys. I know there are 2 cams available, one from crane cams and the other from comp i believe. I would like to know the difference between the 2.

also, i would like to know of horsepower gains, As well as, do these cams increase fuel consumption??

i also live in california, and i'm pretty sure these cams do not have a california e.o. number. are they so radically different that i will fail the emissions testing?? if it helps, i now only have one catalytic converter, the magnaflow high-flow unit that is legal in california.

uhg i hate this state!!

Ok, so from what i've seen the comp cams 31-255-5 cam is the best choice.

Im still wondering about the gains with this cam. as well as the california viability, i know it is illegal, i just want to know if i can get away with it or not.

also, do i have to use new lifters when installing a cam?? i rather not, because i would like to make the job as quick as possible.

thanks,
Brian
