No need, I have spare 3.8 v6's from Vn - Vp, From owning a vn and a vs i have found that the buick is alot more responsive than the ecotec, Ecotec is based in topend power, Buicks still lead the 1/4 mile times for the commodore v6's (holden stats, vs has more weight but more hp), I personally think the LEXONA has a 14 in it, Other's might say otherwise.
