So I bought an '87 K5 last March and it spun a rod bearing before I even drove it for one week. It's been a long road to becoming a daily driver again, but I gotta tell ya, I love this thing. I joined ck5.com after my engine blew up and you all have helped so much and I'd like to thank everyone of you. What I've done: Rebuilt the TBI 350 as a 383 with new cam, reworked heads, camaro TPI fuel pump, adjustable fuel pressure regulator, new clutch, headers (plus a sweet new 3" single exhaust w/o muffler), clutch master/slave cylinders.... and now I'm making my own ECM chips! It's kinda weird when the first/only time I drove a K5 or anything this size was for 4 days and then I spend 8 months or so getting it driveable again (it would have taken a month if the finances were there). The most I've done to a vehicle before this was general maintenance and a timing belt for my old toyota car, so it was real sweet when my rebuilt 383 fired up on the first try (they don't even do that on TV most of the time). Not a bad jump, and now I'm addicted! So now that I got a decent (still needs some work) ECM chip, I've been using it as a daily driver for a couple weeks now, and I gotta tell ya I LOVE it! It's got a ways to go but that's the fun of it! I've gotten used to driving it for the past couple weeks and it's starting to feel like a car instead of a huge hunk of metal. Things I wanna do next: new heads and beef up the TBI and intake, spare tire carrier, shackle flip, detachable sway bars Anyway, just wanted to give you guys a shout-out and a huge Thank-you for being here.
