yeah, thats the big thing thats keeping me from it. 
Its either that or the 4.3, haven't decided yet, but unless I get a screaming deal on the 3.4, It'll prolly be the 4.3
i picked the engine up for 1500 the ORS kit to do it right the first time 2100 little things 600 total 4200 give or take 500 cause some stuff got sold
making a truck with a 3.0 reliable is just as expensive and i could have went the 4.3 way but then it would be a chevota
