A new motor won’t do much to move the car unless you hook it up to the transmission of choice. The question becomes are you interested in automatic transmissions or a manual transmissions. On the automatic side, technology has come leaps and bounds over the past few years with new options added to the shifting arsenal. Automatics have grown from the simple two-speed Powerglide all the way up to a six-speed automatic and others in between.
There are a few things to consider when choosing an automatic. What will you use the car for? Daily driving to get the groceries and run endless errands or is it a fun car, Sunday only cruiser?
You may want to consider whether or not you want a computer controlled automatic transmission. If you are going for all out quarter-mile action, then a older non computerized low power robbing Powerglide, TH350, or TH400 might be the best way to go. If you want the added fuel economy an overdrive will bring, then you will need to look into a 200R4 or a 700R4 transmission in this post
Most of these are still non-computer controlled using a TV cable to adjust line pressure. The higher end of overdrive transmissions will be the 4L60, 4L80 four-speeds. There are even six-speed automatics out there like the 6L80. There are heavy duty units made to handle a lot of power and offer great control over shift points. The only issues with these will be the higher cost of the units and the necessity of a new shifter. Again the aftermarket has those parts.
Now, if you are the kind of driver who wants to take full control of the shifting for drag racing or autocross events, then we recommend a manual shift. Just like the automatics, manuals have become modernized with time. Even though an M-22 four-speed is the old school king of muscle car manual gearboxes, they are getting scarce. While the Rock Crusher will hold a lot of power, the newer versions not only can handle the horsepower, but have one or two more gears.
Swapping a five- or six-speed has gotten a lot easier thanks to the complete kits that are out there that allow change over transmissions which bolt in as easy as a factory transmission. Just know that even though most of these kits are complete you will still need to track down a clutch pedal assembly and clutch master cylinder.
You have to decide if you like to shift gears or enjoy letting the transmission do all the work for you.
