Run better with more back pressure = NO.

A 305 pulling around a truck that big will have a lot of work to in any case.

Yes, the reluctor wheel is pressed on. I'm sure standard Turbo 400 gears will go in it's place, just make sure you can get what you need. The VSS is not horribly expensive, buy it and you will never have to mess with it again.

Hit the reluctor wheel with a big drift and hammer to knock it off the shaft (toward the trans). I then stuffed the trans with rags, and cut the wheel in two with a Dremel. Not too hard.
