Pat: I don't doubt your times or horsepower figures one bit. I say that because my old Mustang with a cross-rammed 302 ran in the high 10's. Then again, it couldn't get out of it's own way until about 5000 rpm either : )
I would only add that if you were runnng a Barry Grant based carb / fuel system, you could have probably went even faster / made more power with a David Braswell carb system. Every time we've gone from a BG carb to a Braswell carb, the power and times are inferior. Having Air Flow Research do your heads was a wise move. They are the kings when it comes to doing small block Chevy heads : )
It is amazing to me how some of these guys have "decent" parts, but can never get them to run the way that they should. As a case in point, one of my friends had a 1970 split bumper Z28 small block Camaro. It ran decently, but i always new it could run better. One weekend, i told him that we were going to get that car running like it should. Most of the difference in power came from making sure that the basics were right i.e. plugging small vacuum leaks ( less vacuum means less torque ), proper power valves in the Holley, proper jetting, proper timing / advance curve, proper valve lash ( solid cam ), proper pressure in the tires, different launching strategy, etc... The difference in before and after times was almost 2 seconds in the quarter and GOBS more torque and driveability on the street. Sean
