was just wondering your expieriences with "orignalists" i know some on here are and thats ok, i just get PO'D sometimes when someone comes up to you or tell you how it was out of the factory dont touch it or your an @#$&^%#$%^&.
i recently joined a site and told of my idea to put a sbc in the truck HOLY cow youd think i was asking to rape and pillage a cemetary.

a gmc and a chevy are identical except for engine and trim correct? at least in 66 and down?

off my soapbox i go.
