413 built bracket engine drop in ready

May be good to post the cam card so folks can get an idea of the motor’s intended RPM range.

May also be good to post valve spring part number and installed height so folks can get an idea of the spring loads. Your text says triple springs (did you mean dual with damper?) which could be a lot for the flat tappet cam (you didn’t say solid or hydraulic) unless maybe they’re set up light for reasons.

Thanks!
