I use a Dart block, Bryant crank (4.25" stroke), GRP aluminum rods, and Venolia pistons (4.5" bore), the engine has a peterson dry sump, also have all titanium valves and good springs with T&D shaft rockers. I still run a standard diameter camshaft and lifters. I check valve lash and spring rate after each weekend of racing along with regular oil changes. The engine has won countless events and championships without a failure. So I would say it CAN be done.
