Strokersix,
Nice build, I am following it closely.
With all the 16 pages of detail I just had to run this one thru the DeuceCoupe Gonkulator computer.
Here is what it computed to, with the info you gave and assuming that 396-2v carb is the 1.25" venturi style (381cfm at 3.0" rating)
I also computed a 9.46cr, not sure how you got 8.8cr unless I missed something?
Anyway here goes:
Torq 324 at 3300
Powr 257 at 4500

And with a good bite:
2.18 60ft
9.25 at 75.8 1/8mi
14.52 at 92.2 1/4mi

Using 1-5/8 headers instead of 1-1/2 only added 3 hp, and was better by about .02 sec and .2mph. Not worth it. \:\(

Adding a 600cfm Holley was good for 28hp, about 25sec and over 2mph in the 1/4 mile. But then you'd lose the fun of showing people your Nova taillites with not only a six, but a 2-barrel six. \:o
