I'm looking for a an emissions friendly roller cam. Does anybody know of one? I have a F4TE 351 and I need to have a cam that will pass emissions. The car is a 5 speed w/ 3.27 gears. AFR 185 heads GT-40 intake. It's a daily driver (1500-5500RPM). The E-303 is emissions legal, but it's 20 years old. I'm sure there's a cam that will produce more power and still pass an emissions test. That leads me to a second question: What specific criteria on a cam makes it pass/not pass emissions? Thanks in advance for your help.
