I just got done watching fast and furuos 6 and I relized that a v8 would be allot easier than tryin to mod this 4 cilynder. What v8 would fit well ? I found a ford 5.0 with the vortex heads for WAY cheaper then the replacedment kia 4 banger, at the pull your own yard. can i make a 5.0 fit in my Spectra? my cousin knows how to weld really good so no problem there.
