I'm continually amazed at just how fast a 400cc JLO in a prime state of tune actually is. Gerber's D/stock is only a 400cc engine as well, from my understanding. It's a 5-port engine, but for a regular old 400cc axial fan engine, you sure get a heck of a bang for your buck with them. If you can get the airflow worked out well with a well-tuned carb and exhaust, get your clutch and belt adjusted right, get the right cruisin' sprockets on there, it's tough to beat on a budget.
The McKay is likely the same story (amazing state of tune, and just set up perfectly), although I don't know if the heads have been off since the mid-seventies so anyone can take a look-see at just how that thing is put together. Sometimes, everything just comes together in one extremely strong, tight package, and it "just works". It's troubling sometimes when you try and try to replicate the machines that work so well, and nothing seems to be going right. I can attest (after years of just such struggling) that when stuff finally comes together, and you squeeze the throttle on that straightaway lap after lap, and you feel the machine putting you back in your seat allll the way until turn one, and that 6000 rpm scream just gets sweeter and sweeter, it's a good day.
Ignore the grenaded bearing carriers, the broken chain, and the melted down piston. That's all little stuff.
