Good question. I have two cars. One is a stock shortblock/cam and the other has forged pistons and a 210 roller.
Hidden in the wood pile is the subject of timing. Most would probably agree that boost makes more power than does timing, I think.
On the car with the stock cam, I run 25 psi at 18-19 degs of timing whereas with the 210 cam, I have run as high (by accident) as 29-30 psi with, I think 19 degs. On both cars, I have a problem with running more than 20 degs in 1/2 because I cannot plant the tires on the street.
In either case, I cannot run as much timing on alky as some do. It would probably be better on the alky control kit as it sprays more than the Chlupsa kits that I have.
When I add timing to the high compression, I get more torque than I can handle on the street with 275/60's. I firmly believe that more boost is better than more timing as the additional timing builds too much heat too early in my case. Higher compression restores some of the bottom end that the longer cams take away without having to add more slip in the converter which often cuts off the bottom end of the power band.
I would guess that something around 208 degs is a good match for 9+-1 cr for a street car.
Race cars spend their lives in a very narrow power band and are a whole 'nother subject. Race cars are much simpler.
