What to expect out of mild build 360

What is your combo and car weight? Impressive
Car weighs over 3200 lbs with 1/4 tank of gas, no spare, without driver. Stock smog heads, stock dished pistons, stock crank, stock rods, how about I say stock long block with a .427 lift / 204@050 cam (less than a factory 360 4bbl). 750 Holley DP on a eddy intake. Headers/duals out the back.
