Yes I am still planning on doing the conversion, just having a few ideas about it... say I found a 95-98 Z71 without a motor or tranny (ext cab), would it be any different than my reg cab to do the LS1 swap? would the differential or any of the 4x4 components get in the way? and what about gas mileage, i know z71's with the 350 get like 12-13 mpg, would the ls1 be able to bring this up to maybe 18-19? i know the tires (i would most likely keep it stock though as far as tires or lift) and 4wd affect the mileage alot... im just curious... because ive always wanted a z71, but hesistated because of the mileage. it'd be nice to have the extra space to carry passengers vs. my reg cab, but i dont know. Just hoping i could get some feedback from you guys... and dont worry i am still gonna do the swap either way... Thanks!
