I have unexpectedly (long story) found myself in possesion of a 1972 Chevelle station wagon, it has the original 350 motor w a 2 barrel carb.
I'm obviously no mechanic. Would my grocery getter even have the power to pull my AS?
Any input/opinions would be appreciated.
A definitive answer isn't easy without more information, but the mid-size 1972 Chevelle could be able to tow your Tradewind. Since your Chevelle has a 2-barrel carburetor, it is unlikely that it has the options for towing but most of that can be addressed through upgrades. I suspect that you would be looking at the following upgrades as a minimum:
- Four barrel intake manifold and carburetor.
- Dual Exhaust system.
- Heavy-duty replacement radiator with either 3-or-4-row core.
- Heavy-duty transmission fluid cooler.
- Differential gear change . . . likely has either 2.70 or 3.07 ratio from the factory . . . a 3.73 ro 4.10 ratio would be desirable for towing.
Fortunately, GM began installing hardened valve seat for unleaded fuel in 1971 so you should be safe in that area which is a big savings . . . my '65 Dodge required nearly $1,200 in head work to permit the safe use of unleaded fuel when I decided I wanted to use it as a tow vehicle. My family had a 1971 Buick Sportwagon special ordered new in 1971 with the trailer towing package and that included the following (which would have been a near twin to your Chevelle wagon):
- 350 cubic inch V8 with four-barrel Quadrajet.
- dual exhaust
- 3.23 differential gearing
- heavy duty alternator
- heavy duty radiator
- heavy duty wheels with H78-14 bias-ply belted tires
- heavy duty shock absorbers
- heavy duty springs
- trailer towing wiring harness
Our RV dealer added a heavy duty transmission fluid cooler and the custom welded Reese class III receiver hitch. While the trailer that we had at the time wasn't an Airstream, it weighed about the same amount as your Tradewind and the Sportwagon was a wonderful tow vehicle.
Good luck with your investigation!
