    was thinking of replacing the engine in my 97 tahoe with 220,000 miles. it doesnt smoke or anything yet but i think i'de still like to do it. i was looking on the gmpp website and couldn't seem to fine a direct replacement. anyone know which crate motor would fit the bill? anyone know if my vortec heads will fit on any of those small block motors? i would like to reuse my intake and my vortec heads if possible.

    If you plan on using the same intake and heads why bother replacing the engine at all. the valves will be worn and springs could have some sag in them, the intake will be all dirty and full of gunk, just get a whole new motor or just rebuild what you have and have the block bored out. Or go and get a stroker kit for it!
