Idles nice and smooth and made peak at 5700 and makes 14" of vacuum. Perfect driver with lots of grunt. I have the trans setup to shift at 5800. It's a happy engine just lifters are noisy
I am familiar with those cams. That is a poster child for having an aggressive intensity. 50* intensity is 55 mm cam tunnel territory. I have done 49* before. It takes ultra ultra razor sharp lifter bleed rates to make that quiet with a SBC cam journal. They run good but usually you have to live with some noise. But I would have thought though the evo could handle it if any could.
