Probably the biggest cams made for the miata. Jesse Prather had these cams made for me about a year ago. They are the same cams used in the e production Miatas that he builds that make around 200whp. I know another Guy using these same cams that made 220 whp in an engine a bit wilder than eprod.
My engine made 185whp with only 11:1 conpression and believe it or not it was perfectly streetable.
They have very little miles on them. Dyno time and a few hundred street miles then back to the dyno where that engine decided to throw a rod.
The cams have been checked by machine shop just to make sure and they are perfect. You must clearance the lifter bores for these cams, as well as dent or modify the valve cover baffling.
