Help Gathering Info on Inherited Motor

Just for kicks I get this;
Static compression ratio of 12:1.
Ica of 80*, elevation 1000ft
Effective stroke is 2.46 inches.
Your dynamic compression ratio is 8.22:1.
Your dynamic cranking pressure is 164.08 PSI.
V/P (Volume to Pressure Index) is 144

>I only used 12/1 Scr because that number was mentioned. This would require a total chamber volume of 83cc, so the head chambers themselves would have to be really really small.

>To get the Ica, I used the following
180less[{(312/2 less104)+360}less312]=80

> I got the elevation from WIKI

You should be able to drive that on the street if yur careful; I mean I would at least try it. No you won't need a gnarly TC; the VP is estimated to be 144 so that's just right, and it will pull 3.23s just fine.
I think Rusty nailed it.
I'd put a tiny 4bbl on and try it as is, give Dad some credit.

Just don't try and make it into a tow-truck engine.
Your cooling system is gonna have to be tip-top.
