So, a while back I got confirmation that a 6 lug rotor is available that will go on a 14bff rear disc settup. Has anyone got this setup/conversion? If so, how much was the complete brake kit? What do you use for an e-brake then? I know I've read about this, but can't find anything via search. Is there anybody that sells the entire rear disc brake kit? Who sells the 6 lug rotors? I saw someone on ebay selling the brackets and then just a parts list for your local parts store. That might work too, but I want a ballpark of cost. So, what I plan to do then if the six lug rear disc is available, is to get a 14bff with 4:56's, open carrier, and install a detroit carrier. Then get a detroit and 4:56's for my corp 10 bolt front. Then put in a decent top end and headers on the tired 350 TBI, maybe get a performance chip, and call it good. That seems easier, cheaper, and faster than trying to get a 3/4 ton parts truck and swapping stuff in between. Getting 36 IROK's too baby! Speaking of top ends, I think I read that newer vortec small block heads will fit on a 1990 350. Also, I read that it is advantageous to get a high flow intake manifold like an edelbrock or something and then just get a TBI adapter plate. Last is the cam. I heard that comp cams has a good RV cam for this type of setup. Speak up please, this is my best plan yet, and the 250K miles she has is getting the best of the K5 DD. Once I get her all fixed up, then it's time for a rice rocket DD of some kind and time to scratch the hell out of the K5's paint off road.
