Engine builder questions

Here's a rod that might be usefull http://m.summitracing.com/parts/esp-6300hj it's a 6.3" Chevy rod with Honda bearing size 1.89" I don't if you can turn a 340 crank down that much but if you can and bore the rod out to a .984 dodge piston pin you could get a 2.91" stroke with a 6.3" rods with 4.07" piston with a pin height of 1.804" = 9.559" and mill about 0.040" and you'll have a zero decked 303 CID.

I'm interested if this would work I might have to change my 273 build plans to a 303 :)
