Im part of the fullsizechevy.com forums also and on that website "The big 3 upgrade" seemed pretty popular. How ever I sold my truck bought a camaro and then joined this forum. I still post on the other boards but nto as much cuz there isnt as much of a point. How ever i havent done much digging at all for this but on the first 1 or 2 pages that i looked none of the big three upgrades. Is there a reason for this or what? Has any one on here done it? Any pictures?

 

i just run a larger battery and a alt thats about it , plus the grounding wires and ****

 

for the most part isn't that what the big three is? battery to alt battery to ground. And alt to ground. or something along those lines?

 

It's not on the first few pages because it's been covered a million times. Just search.

 

Battery -neg to chassis
Alternator to battery +pos
Chassis to engine

 

You could take it a bit further if you wanted. I did the battery to chassis ground(fender), battery to engine block and engine block to chassis (ground strap at back of cyl. head) as well as battery to starter and battery to alternator. Made a difference.
