Cam to get every little HP possible?
I do a computer test here for emissions, the dont do a breather on OBDII, I've heard anything less than 112 LSA is too rough for the computer to pass the car. I dont want to change to a solid roller setup yet cause I just built the motor hydraulic roller. So I am looking to change the cam only, I think my springs go to a .600-.610 lift.
My setup is a cast SCAT 3.75 crank, PM rods rebuilt, speed pro hyper pistons, fully ported lt1 heads, 1.52 rockers, 2.00/1.55, comp cams beehive springs. oh 2 bolt main with arp bolts
I also dont want to really push my rpm limit although I do want everything i can out of this motor because I dont plan on spraying, my goal is in the 11s on motor, i dont mean like 11.99 know what i mean lol
Just give me some ideas, because this is my 3rd fbody but only the first ive modified, so im new to this stuff. Need all help I can get. Thanks again
The cam someone recommended was 236/242 .585/.596 112LSA
Can I get any more aggressive and what rpms will they probably take me too. If 112 is emissions safe and 110 isnt, can I get a custom grind 111 to pass. Need INFO???

well if you want to squeeze every bit of power out of a cam and still pass emissions, dont buy an 'off the shelf' cam. have someone taylor a cam to your specific car and needs!
and a custom ground cam doesnt really cost that much more then an off the shelf grind, especially if you figure in the potential of it over the other IMO
