Hi everyone!
Signed up the other day with a question about installing a big block radiator in my small block burb, and met a few of you there, but hadn't had a chance to do an intro yet.
Back in about '04 we were looking for something that would haul the 3 of us and a dog or 2 on camping and skiing trips, and so that as our daughter grew up, we could be the family that took her and her friends to the movies and other kid stuff. I'm a German car guy, and wasn't really into GM iron, but both of my brothers were, so I'd been around quite a few square bodies.
As luck would have it, there'd been a 'burb of some sort languishing for months at the local Goodwill Donation Center. We decided to go have a look. It was peeling paint off the roof and hood, huge dent in the passenger front door and rocker panel, nearly flat right front tire, and the front carpets looked like about 500 cups of coffee had been spilled into them. In fact, there were coffee stains running out of the backs of the front seats, and about a 1000 packages of sugar and stir sticks on the dash. 225k on the clock, but unbeleivably, not a hanging drip of oil or other wear signs anywhere. Gave the ignition key a twist and it fired right up!
Paid $1,900 for it, then took much of it apart to have it repainted in the original white w/ Dupont Nason Urethane. Bought a couple of used seats at the wrecking yard, stripped the grey fabric off them, and had the front seats rebuilt, including having the frames welded where they were broken.
Put it all back together with new wheel well trim and badges from the local dealer, and an OEM Stereo CD player out of a similar year Buick.
During the reconstruction I was able to get in touch with the local original owner's who'd purchased it as a demo with 10k on it, from the dealer in San Jose, CA. They told me it had never had an engine or a transmission, and affectionately called it "James....the mountain taimer." In fact, the cover on the dash had "Mountain Taimer" embroidered on it. The gave the local dealership permission to give me all the service records, and I was able to see what'd been done to it over the years.
One of the first things I changed was the passenger car type tires they had on it. It was ridiculous to drive because at about 55mph, it started weaving back and forth because of the mushy side walls. I put a set of BFGoodrich Long Trail TA's on it, and it became a truck. I've now got a set of General Grabbers on it, and like them even better.
I've rebuilt/replaced just about everything on it, starting with the front and rear a/c system, including converting it to R134a. At 235k the transmission quietly lost 3rd and 4th. I drove home in 2nd and had a local guy who built tranny's for the GM dealer, rebuild it. We picked out all the "new" ****-bang parts like you see the Raptors are built with. It lasted 150mi before loosing 3rd and 4th again. Rebuild #2 lasted 30k before loosing 3rd and 4th yet again. So we're on rebuild #3, with a mild shift kit this time, the most current ****-bang heavy duty parts, and the upgraded steel apply pistons form the 4L60E's. Been about a year, and so far, so good. During that first trans rebuild I upgraded to a big B&M finned cast aluminum trans pan that holds 3 extra quarts, and is bunged for a mechanical temp gauge. That temp gauge is mounted below the dash, just forward of the 4x4 shifter. I also installed a big Tru-Cool (same as B&M Super Cooler) trans cooler, and a pusher fan out of a 3/4 ton. We do a lot of towing in the mountains and in the heat, so I try to do mods that help with that.
I've got a bigger set of rear springs, a huge rear sway bar, and an axle truss to help stiffen up the soft 'burb tail, and like how those have worked out. Not sure the truss does anything, but it was $20 at the local yard, so what the heck.
The most recent work includes an Edelbrock TBI intake manifold, and just a couple of days ago, an upgrade to the standard width big block radiator. Needed a new radiator, wasn't feeling the love for the ally/plastic versions, so figured I'd just go with a nice used BB version.
