Anyway to calculate vacuum from camshaft overlap?

I'm quite sure with the correct cam specs it will idle fine. Pat G knows how to nail the overlap deal perfect..... I wonder myself how critical the lobe separation angle is on the vacuum situation

If I was go do a hydraulic roller motor with a Fast 102 I see no need for a square port cylinder head for a 402-418ci setup.
Me personally I would do a set of Tooley 245 heads rubbed over with the intake ported to match then a badass setup from nitrous outlet if I was go spray. Maybe even a direct port nitrous setup.
Plenty of cars running 9s and 10s on motor with a Fast intake and hydraulic roller with cathedral heads 205cc-245cc intake runner.

64post- I asked Brian Tooley maybe a year ago about the 235 vs 245.... basically said the 245 is the way to go even on a 4.000 bore engine. The 245 head gives you room to grow he said.
235cc is 2.08 intake valve vs the 245cc head is 2.10 intake valve.... not a big difference between the two on paper.
