im kind of wanting to do a 4.3 swap into my 1993 s10 tahoe. i completely realize i will need to change mounts and such but will i need to do as many modifications as i would if i wanted a small block? i figured a 4.3 is a popular motor, gas mileage isnt much lower, and the power is a lot greater.

Easier to do a 3.4 swap and its got about 20 less HP than a 4.3 and alot better power curve IMO.
