Re: Previous owner '68
So I decided I would do a leak-down test. I know, the results might be different if the engine was hot and fully oiled, but I did it anyway.
Test psi was 100psi and I did test both at top stroke and bottom of each cylinder. Results were: Cyl 1 top - 90%, bottom - 92% Cyl 2 top - 84%, bottom - 88% Cyl 3 top - 84%, bottom - 80% Cyl 4 top - 90%, bottom - 90% Cyl 5 top - 82%, bottom - 80% Cyl 6 top - 86%, bottom - 84% Cyl 7 top - 96%, bottom - 94% Cyl 8 top - 90%, bottom - 90% Now this was a long sitting, dry engine. Given the results I am going to replace the valve guide seals and hope for the best. If you think I'm screwing up let me know.

Re: Previous owner '68
Looking at how clean the valley is on that one, and your cold test results, I'd say it's a runner.
