HRoss:
Regarding your quote "It is also no secret that small and or big block (of early vintage) cannot really sustain high RPMS due to cavitation in the
oil pan....they were just never built to do that.",
I do believe (and guys correct me if I'm wrong), that the Ford 289 was the first American small block to run for 24 hours straight at over 100mph, establishing a world record in '63 or '64. Now that may not have been at 7,000 rpm the entire time, but it had to be turning some decent revs.
Obviously, you've been taking a lot of flak here, but hey, it's your car and you should do what you want. Just be prepared for the car shows and cruise nights, where people will come up to your car with a huge smile, then get a glimpse of the engine bay and just walk away shaking their heads. But you didn't build it for them, so if you're happy with it, then that's all that matters.
