Awesome Dart! I have a question about your piston selection. I'm building a 4.5" bore gen 2 hemi and using Edelbrock heads as well. I plan to use a Molnar 4.250" crankshaft, but I am not sure what piston will work best with the Edelbrock combustion chamber. Can you give a recommendation? I'm also looking for about 11:1 static compression.
