Ok, but what will cleaning the negative battery cable ground do?

I believe I'm going to try and get a starter heat wrap to add to the sheild I already have.

I didn't do much of anything yesterday other than hit a few things, and steel wire brush the cable just a little bit, and the truck turned over better than the it ever did(in the past year).

Again, thanks for all the help.

So Mil1ion, your saying take the ground off the block and unbolt one of the starter bolts and bolt it there?
