340 dyno chart thoughts

That engine looks like a fun engine in a street car especially given the broad torque and quality idle. Those characteristics make for a fun and enjoyable ride on the street.

If it's a fresh engine broke in and dyno tuned, I'd run it and enjoy it for a season. If you are looking for more than next season make a cam change or try a few other things.

I like this cam if it were mine and wanted hyd cam with a little more power while retaining the style engine you've put together. I.e broad torque and friendly idle. Crane 694561 with a 1:6 rocker.
