273 Performance build possibilities.

I’ve got a 273 with high hp for the street. All custom built- custom pistons, custom ground cam and balanced and lightened lower end. 66’273 closed chambered heads, 5/16” stems on the valves. Machine shop built. The fully squared the block before anything was done. After the price tag I’d do a 318 if I was to do it again. Especially since it is in front of a 904 and 8-3/4 with 3:23 rear gears and 24.5” tires. The life expectancy of the engine is less than 40k
318 all day long. Magnum actually 318.
So many parts and off the shelf.
