427 SO with Lunati 20501 Cam

[66gtk]

I'm wondering if the collective knowledge base here may be able to shed some light on possible estimates for me on HP and torque.

My ERA has a '68 Side Oiler with stock bore/stroke. It has 390 heads (c1ae-6090-a) and dual Holley 600 CFM carbs. The rear is 3.31:1 and has a wide ratio toploader. The Cam is a Lunati 20501. Autolite #45 plugs (.035 gap), valve adj: .24 in, .26 exh., 10 degrees initial timing.

The car runs fantastic - idles smoothly at around 800 RPM and seems to have tons of torque. Very easy to drive on the street (which I like) and I usually find myself wanting to shift around 3000 RPM through the neighborhoods. I've never had it over 4200 RPMs as the car is new to me and I don't know what the engine can take.

Any estimates of what kind of HP and TQ I might have and when the best shift points may be as well as red line to stay away from? I can only imagine what it sounds like at 5000 RPM as I don't want to destroy this beautiful engine.

Thank you in advance for sharing your knowledge to assist me.
