My 66 L72 is back together, broken in, and running very well

It was built with all NOS parts, is .060 over, has an oeifinal L78/72 cam and lifters etc
Factory Holley with stock jets.

The only mod is that i have the “give no mercy” side pipes on it so a bit less restriction - but i thought Id ask here.

Anyone have an improved jet formula for this motor? Or is the stock jetting the ticket?

The correct jetting for your car is primarily dictated by conditions (atmospheric, altitude, etc.). This video will help you out (and yes that’s my video):
