69chvelle: I'm running the Texas Speed Torquer V.3 (TSP Torquer v3 231/234, .643"/.598" Camshaft)... I swapped them for the Patriot Extreme dual springs. My wife has an urge to race the car now instead of daily driving... To be completely honest, the springs probably have about 500 miles on them. Still have the factory paint marks on them.

These are great springs, bump for the seller. I run them on my 238/247 .640/.610 cam. They are significantly quieter than duals, and when I checked the pressures on mine they were actually higher than rated from Manley (rated at 150 closed pressure and 375 open, mine tested out at 161# and 406#) which is almost patriot extreme dual spring territory. Interested parties should have no qualms running a single spring even on a decent sized cam, and these are some of the best singles you'll buy.
I don't remember the weight differences, but with the spring and stock retainer it was significantly less than a dual with a Ti retainer, then I added Ti retainers and came out so light it was crazy.
