lsa ?

[72chevy]

What difference in driving characteristics with different lsa's? I am thinking about a 181 210 & will be running 362-475 twins & want excelent spool up. This will be on a 12v btw.

Tighter lsa's seem to make the charger come on a little better at the bottom end, but don't work well if drive pressure exceeds booost pressure, so fro most people a wider LSA is best.
