I had a small VC leak that I wanted to fix, so this evening I pulled the cover and here is what I found.
1147 heads, D3060 date code (makes me happy). Valve springs installed @ 1.761 and 142 pounds seat pressure and have a 279 lb./inch spring rate.
To I guess more evidence that the deck stamping is correct and this could have been a 335 horse.
Tomorrow I plan on doing some limited cam mapping, at least lobe lift measurements.
And of course some pictures.
