1976 l-82
I just bought a stingray thats a 350 L-82 want to tune up and am looking at a hei upgrade kit from summit Racing its the summit brand its coil, module, cap, rotor, vaccume advance etc, Am I asking for trouble doing this Kit comes with an adjustable vaccume advance dont think mine is will that work?... Also with my sheilding am looking for wires to go under headers? am I asking for trouble getting away from ac delco? how about Taylor wires ?anything I should know that could hurt oh say radio interference or anything something I need to make sure it runs like it should? any help would be greatly appreciated thanks

Getting a fancy bling ultra high voltage ignition system will not assist performance in the least and is not money well spent.
If your distributor is stock, possibly having the advance curves modified would help a little. This might not be part of the kit you're looking at.

i beleive your car will benefit from a distributor tune up but mostly from taking it apart and cleaning and lubricating it. the adjustable vacuum cannister is not worth anything and a stock working unit will suit your need just fine. be sure to shim the distributor shaft if you need to and buy those shims when you order your parts

the real benefit will come with taking the distributor apart and lubricating the advance shaft if it is sticking....check and see if this is sticking in any way if it is take it apart. if it moves freely then dont worry about taking it apart.

I just replaced advance springs and weights on my Mallory HEI. If the weights move freely does that mean the advance shaft is fine? If not, where is the advance shaft and how would I check?

i dont know about mallory HEIs but on stock ones there is the cross shaft that throws the weights out this needs to rotate freely
