Here's why I asked about the L-100 in a small engine. Long ago I dealt with a customer's 327 SBC that had stock low-perf heads and a huge cam (Anyone remember the "Optional Z-28" cam that chevy sold over the counter? I was told that's what it was) The result was an engine that ran out of air just about where the cam started to work. It wasn't lack of carburetion, it had a 65 Corvette fuel injection unit on it.

So it had a super nasty sounding idle, and a soggy bottom end, and ran strong from about 4500 to 5000 rpm then distinctly stopped pulling at 5000 presumably because of the combination of 327 CI and the small heads.

Would a 221 w/L-100 do the same thing, or would it continue to make power at higher RPM?
Related question, how much rpm will 221 rods stand up to?

I understand about gearing and weight and torque curve, have dealt with that many times in many ways, I just wouldn't want to build an artificially stunted combination. (I find a high revving engine fun to drive, you don't need big torque when you have horsepower!)
