Very cool. I just am not sure what SOTP means. All this without the aid of an oscilloscope? Impressive.

I always did wonder if tall valve covers could fit in a vette or not. I bet those shaft rockers were pricey as hell. That probably means you have a new set of custom pushrods, too. Never was sure if you had a rev kit in that thing, either. I suspect the only improvement left is titanium valves and pneumatic springs.
