L79 hyd. roller cam upgrade

[67since67]

Looking forward to the next project.

Any recommendations on a hydraulic roller to replicate the 151 L79 Camshaft? Most important is the idle quality (sound) and to replicate drivability of the GM 151 cam.

Normally I would opt for a "blue print" flat tappet, but recently I've had two friends that each had TWO (2!!) successive FT cams go flat on the break-in in their respective BB engines.

Dave got lucky with a freebie used cam and lifters that were perfect for his app. and runs great. Chuck is going roller.

I am open to any recommended cam grinder.
