Greg : the "lowered vehicle" argument was, to be blunt, a buncha BS from Edelbrock. Stock height CAPRICES have had problems with it as well. It's a crappy design : Edelbrock knows it, but evidently isn't inclined to do much about it. Ask mn mark on this forum about HIS recent experience with Edelbrock (in other words, lifetime warranty : yeah right

).
Once you drive a car with much better shocks (i.e. more expensive), you'll understand why folks spend the bucks on them.....
On an SS, I'd go with Konis or the stiffer Bilsteins for handling, the softer Bilsteins for "some" handling with better ride comfort, or the Hal 12-way adjustables if you drag race.
