Engine builder questions

Has anyone ever installed a 3.58" stroke crank in a 273? Here is the part link http://www.summitracing.com/parts/dcc-5007257

With a .030" 273 should put it at 3.67" bore and yeild 301 cubes correct? The reason I as is because I am bulding a 65 Barracuda to compete in SCCA Prepared C class. Anything under 5,100cc or 5.1litres gets a 300lb weight break, so the car can weigh 2,700 lbs and be more competitive against the 302 mustangs and camaros. Anything over the 5.1L will have to compete with the big boys.

I know that Ma mopar used a destroked 340 in Trans Am racing, but I don't have one of those cranks laying around and I doubt anyone does either. LOL

If anyone has done this then I have a few questions. What pistons can I run? How much meat is there on top of a set of 273 pistons, can they be machined down? What is the biggest intake valve that I can run in that tiny bore? 1.88"? 1.92"? I know there will be valve shrouding, but I also want the engine to perform.
