Hey guys, there has been some talk & I've read quite a few threads about timing & having the correct distributor curve for your application. I'm trying to figure out if my dist. is set up correct.
I have a 72 Q code with a/c. It has been rebuilt .030 over with a larger than stock hydraulic cam, stock 4v heads w/steel rockers, nothing wild, just a mild rebuild. I have a Performer intake on right now with a Holley 770 Street Avenger carb. It also has a c6 auto trans w/3.25 gears.
I will be switching the Performer intake for a Blue Thunder, but I really want to make sure my distributor is set up right. It's a stock unit w/the Petronix added to it. It's actually running pretty good, but I know there is more to this timing that I want to learn.
I the pic I have below, it's set up using the 10L slot, which is 20* of mechanical advance, & I set my initial at 15* BTDC. That gives me a total of 35* (w/distributor hose plugged off), am I in the right ballpark for my application?
I'm not sure about the springs, looks like one is different than the other. I don't know if the PO installed the lighter spring. Any help would sure be very informative. I've never really got this far into the timing.
