I was told the 4.25 stroke and 4.25 bore was the way to go, but every builder is different. Some build 496's or Roush offers a 511 FE. Some build the 527.
For someone like Dean who's an accomplished racer the .125 stroke difference may make a difference in "ramping up", but so does using an aluminum flywheel or even starting with few hundred extra lbs that a fiberglass car has versus an aluminum one.
I'm not sure a mere mortal like me would see that .125 stroke difference. Sort of six of one, half-dozen of another.
Enough is enough? Hmmmm. Never been part of human nature.  |
