Hey just wanted to get back to you on the cam stuff, prob too late but FYI... the stock HO cam from '91-6 is like 270* adv. duration but a measly 197* at .050" and maybe .420" lift. Bumping up to even just 210* at .050" and .460-ish lift would be a huge improvement. Check out JeepStrokers.com there's tons of testimonials and info on aftermarket cams. I've got my eye on a Crane, I like the Voodoos as well but the fast ramps reduce longevity.
Awesome build way to prove the naysayers wrong, looks more than doable!
