I have the 6.0 in my reg. cab. My uncle has the 5.3 in his and my cousin has a 6.6.Don't regular cabs come with a V6 also? Yuck, but besides that..I think i've seen a lifted regular cab before and it looks pretty good. I don't know why someone would want a regular cab, i myself love having a bunch of space around me...i guess that comes from being a texan with tons of land around him at all times.
