    Question 5.3(327) swap into a 94 Sierra

    I was talking with my fiance's cousin and he was saying that you can fit a Chevy 327(5.3L) into the 88-99 GM Trucks. Is he correct and if so would this be a worth while swap, compared to a 5.7 swap from a 4.3?

    It will surely fit but those old engines did not have all the pre-drilled mounting holes necessary for late model accessories. You could use late model heads and an aftermarket manifolds and it would work but there would be a lot of little problems to deal with.

    So it wouldn't be a quick swap like a 4.3 - 5.7. Change the computer, injectors and drop in with stock throttle body?
