    70003 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from So far so good! Bought this for my 79 camaro with a lq4, and everything is plug and play love it so far! Quality on everything! The only thing to note is if your are using truck accessories, the throttle body linkage will hit the water pump inlet, but I believe that a f body waterpump with spacers to align with other truck accessories does work.
