Well, since I know it's a definate thing I can only have 1 K5, I want to keep the 84, and put the 87s TBI on it and part out the 87. Now, I just wanna know from the people who have done it, how long does this take? I think my 84 has a spot on the fuse box for an ECM ( Probably for the ESC), and I heard that the 84-up tanks can fit the FI sending unit? is that true? The exaust has an opening for the O2 sensor on the truck, so that's no big deal. I'l also need a TBI adaptor for my performer manifold. I know holley makes one for their TBI kit, but I can't seem to find one seperately. I just wanna find out how much of a pain in the butt this is gonna be before I go through with it. <a target="_blank" href=http://billybob87k5.50megs.com>Homepage of Porky & Stinky</a> "..
