OK, so you're not a novice with a pipe dream, which is what it sounds like when you talk about MSD ignition, fuel injection, and roller cams in 60-year-old engines that were designed to run under 3,000 RPM and rely on low-speed torque to move the vehicles around. Trying to reinvent the wheel on these old engines is like pounding sand down a rathole, but it's your sand, and apparently you have an unlimited supply of it. Good luck!
