OK, I tried the Medium Silver springs with the 600 - 2800 RPM range and I swear they only gave me 8* of Total Advance. I tested them in two configurations:

Test 1 - 0* Initial Timing gave me 8* Total Timing (no vacum, engine all reved up to 3500 RPM) even with my vacuum canister hooked up to give us some more advnace, the truck did not run good, felt under powered, and choked/sputtered/backfired under acceleration a couple times

Test 2 - 10* Initial Timing gave me 18* Total Timing (no vacuum, engine all reved up to 3500 RPM) also with the vacuum canister hooked up, the truck ran better but I would not say good, not full power, I think may have backfired under acceleration a time or two
