It had some other changes too. There were several different version depending on which engine carb combo it was used with. If you have 330 2bbl don't expect it to last forever if you modify the engine. I would just use it until it dies then go to a turbo 350. The 200r4 is also a fairly simple swap and would allow you to go to deeper gears, while keeping the rpm low, in the future. Good luck.

The problem with the Jetaway is that first gear is 1.76:1. As an example, a TH400 has a 2.48:1 first gear. That will make a tremendous difference in how the car feels off the line. A 200-4R has a 2.74:1 first gear. Now add a good 4bbl and free flowing duals and you'll feel a tremendous difference.
Note that for things like intakes, distributors, etc, anything for an Olds 350 will also fit a 330.
