273 or NOT 273?

So lets say a .030 over 273 , ported set of 318 heads , port match a victor intake , solid flat tappet cam , 1.6 roller rockers , 12/1 pistons , lighter rods , stock steel crank , 750 HP carb , 1 5/8 headers , 4 speed and 4.56s. does that sound like it would work on a 273? Not exactly but just a rough draft.


Use a 360 head and 1.88 valves and notch the block.

A 318 head is too small for a 273. By a ways.
