Hello everyone. Just signed up in this forum after being a CK5er for more than 8 years. During all this time, I've been building my 1979 Blazer up to the point that I'm seriously considering towing it. It has a 454, 38.5 SX tires and soon to come 5.13 gears. I'm not only concerned about mileage, but I don't want to wear my Super Swamper tires in pavement. Now my wife needs a new car to replace her 1994 Geo Tracker. It's simply too small and uncomfortable to drive and the interior sucks. I have a friend who's offering me a 1996, 2 door, 2wd Yukon with a non-vortec 5.7 TBI engine in it. It has 61,000 miles a 4L60e tranny, and apparently 3.07 gears in its 10 bolt axle. All for $2000. It's been mantained wonderfully well and has used synthetic oil all its life. The interior's confort is like night and day compared to the Tracker, so my wife fell in love with the car. There's no snow over here, so I don't think I need 4wd. Now for my question, can this rig tow my 6000 Lbs Blazer? I'd be using a dual axle, single wheel trailer from a friend which looks heavy as well. This would be only once a month for maybe 400mile round trips across the mountains in my country. Will the tranny hold? would I feel the TBI engine too weak? Should I install a set of 3.73 gears? I also have a friend who could sell me a 6.2 engine, but that't too much trouble because I'd have to swap tranny as well, and the only other OD tranny is the 700r4, which is not so great for hauling. And if I'm not mistaken, the 6.2 is a dog. All your opinions welcome.
Hmm check the owners manual for the max recomended weight of both the k5 and trailer.I would go for something a bit bigger than a 3.73 I have a 3.73 in my SD and want to get some 4.56's I think the 5.7 would be up to it it just needs to be propertly geared and have enought cooling for the engine and tranny.
