    the best junkyard 4.3?

    what is the best 4.3 v6 you can get from a junkyard? i was thinking a vortec from a late model s10 maybe? the engine will be a mild boost single turbo setup.

    if your going to boost an engine i would get a non balanced shaft CPI engine, they are hard to find, but not impossible.

    you get the LB4 block, but get the L35 pistons, rods, heads and cam.

    ideally you would want to swap to 96+ heads but the L35 cpi heads are still a lot better than the LB4 heads.
