I have a 97 tahoe that I use as a winter driver/tow vehicle and have thought about working with it a bit. I saw GM has a 383 crate motor, but my question comes from looking at the specs. The bore size on it is 4.000", if I'm right the bore size on a stock 350 cu in small block is 4.000". So, would I be correct in thinking all I need is a stroker crank to make this a 383 cu in Vortec? Or does it need .030" over bore like the traditional stroker?
