I tried all 3 sets of springs from the kit, weak-medium-heavy, and also the factory springs, back to back- with timing light hooked up. Every time I put a weaker spring in, the car had more total timing at high rpm.
A street Pontiac with 9 to 9.5 compression needs all the initial advance it can get. the high initial timing setting with strong springs does that. why set timing to 9 to 12 degrees BTDC, when you can just dial in 20 and BANG IT'S ALREADY THERE the moment you hit it, because it's in the initial. NO LAG TIME- ZERO LAG TIME.
then the centrifugal puts in 16 more degrees advance as well. forget the vacuum advance if you're using an HEI, you don't need it.

Why would you argue with "that" guy about distributors ?
