It ran well, but was not quiet as far as sowing machine noise, it has the regular comp lifters, not the evo’s. We were shifting it a 6200, it nosed over hard after 6200.

The cam in this one is the summit 1203 hydraulic roller. LS fire order and 224 @.050
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
