Ok, so I've got a brand new 8.1 (8100, 496 CI) BBC, and I'm thinking of putting it in my 96 1 ton crew. I just put a brand new 5.7 in it last weekend, but I honestly think a 350 is too small for such a beast.

Where could I find a good place to get a harness, and all the goodies to do this swap, and still keep my ECP and all the other factory issued stuff?
