Here's mine 224/230 @.050...268/280 duration...480 lift.
An LA 318, zero decked with 1.81 KB forged pistons, .040 overbore, Indy/Rhs LA X heads with 1.92/1.62 valves, 62 cc closed chambers. .042 quench, a Comp XE268H cam, a holley 4150 650 cfm carb, Eddy air gap intake, a pertronix flame thrower II billet distributor (for now) and a timing chain tensioner and about 9.6:1 compression. Intake centerline is installed at 105.5 on the degree wheel. No detonation at 40* total @ 3800 rpm (something is wrong there with the mechanical advance...I'm still working on that one) with 18* initial 92 octane, 10% ethanol. Dyno results says it likes that timing...less and it drops hp.
At the wheels 2.94:1 rear diff...3.23:1 suregrip in a week or so... 281.32 HP @ 5790 rpm and 257.65 torque @ 5690 rpm. Oh, and I'm going to up it from a 1700 to a loose 2000 or 2200 stall converter to help with in gear and engaged
A/C compressor Idle quality.
Might not be what you're looking for but it likes lots of timing, runs strong on pump gas and has Zero detonation...gas mileage isn't bad at 15 mpg hwy and about 11 with my foot in it repeatedly.
Might consider a step or 2 down in cam for better idle quality and economy. The XE's have a fast ramp on the lobe and contribute to a noisy valve train as well.
