273 Stroker for ***** and giggles

... 4. I would think that heads and flow would be a problem. I was under the impression (I've never built a 273) that larger valves (even 2.02) will not work in a 273. So wouldn't you be limiting the amount of flow your heads are capable of up front?

A 273 will take as much flow as you can give it. I've run 1.88 "J" heads without a problem, no bore notches.

Seems like there was a Cadillac motor with 273 size pistons? Get ready to do the math with stroke, rod length, and piston pin to top calculations before you pick a stroke.
