My suggestion, ride in different cars with different engines. The sound, the power, and the way the engine works through the RPM range is different for different arrangements.
A 351W stroker makes a high pitch sound than a "straight" 351W, and runs up the RPMs faster. But the stroker can make the car more "herky jerky" in low RPM's (my experiance), while the straight 351W is easier to drive. I know a guy with a 460 stroked to 527 in his SPF. Plenty of horsepower. "how much is enough?"
When I went to the DVSF, I saw and heard lots of different engines. What you like based on what you see will be a good way to make sure you will be happy.
While at the Run and Gun, saw the high end of engines, and saw some guys with 350 HP. You know what, they did not do bad either. I have 400 HP (flywheel)on my straight 351W. I'm happy. But I did see these ARAO heads the other day.....hummmmm 100 more ponies????
Good Luck
