Im thinking im gonna build a 400. the question came up what to do with the old 350? I'm thinking i wanna make myself an ebay turbo kit and drive it and see how long it lasts. If/when that blows up then ill throw in the 400. It would be the ultimate sleeper. my car looks pretty trash it was spray painted black by the previous owner who ran out halfway through, and the front bumper needs replacing. I call it butterface so it would be a fairly decent sleeper for the time being. what do Y'all think? Turbo 350?
