its a good swap, but keep in mind no matter how cool it may be to have a rotary, those old Wankels still have the seal problem, and they will go out if not rebuilt and will begin to leak and burn oil overtime. Also keep in mind the RX7 has high gears to compensate for the low torque of the motor. Since you are adding about 1000lbs on load by installing it in a truck, it'd struggle some with stock Mazda rear ends, but it'll get by. What i'd do is also swap in RX7 IRS. since you've worked on muscles and hotrods, you'd prolly know how to do that. that is pretty general.
i'd do it, there aren't many that actually go through with the swap. find one that is boosted and it wont struggle
