Re: 9.2:1 CR in 327?

I traced the shape of the comustion chamber on a piece of paper, and calculated the area with a couple of circles, half circles and rectangles, and came up wit pretty much the same volume/CR as my estimate calcs, so I'm going to play it safe, and use the original 327 head with 8:1CR.
The 327 head has the 'Thunderbolt' on it, which at least looks cool, and from what I have read, the higher CR cuts off breathing becasue there is less flow area above the valves. The extra compression doesn't really add much power either.

Got my OD Trans yesterday after a wild goose chase in the cargo area of the airport (with a hang over and 95 degree F Temps) ugh...
Slowly a packard comes together! Looking forward to the day when we can cruise again.
