depends on whether you're trying to keep the car stock; if yes leave the stock ignition in. Assuming it all works properly, it's not that hard to maintain. If not, have at 'er. Don't stop with the igntion module, you'll want to change your distributor to hei too.

Well, MSD boxes have nothing to do with "classic cars", as they are an aftermarket add-on. MSD stands for Multiple Spark Discharge. The basic concept is that rather than a single spark, the MSD box provides multiple sparks in rapid succession. That way, if the first spark doesn't ignite the mixture for whatever reason, the second or third spark should. Many have argued that a properly tuned stock ignition will work just fine, and there is some truth in that. MSD has evolved it's products, however, and now you can get boxes that have electronic tuning of the spark advance and other features such as boost retard or NOS retard.

What are your plans for the car and what have you done already.

truthfully i just want a bad *** street car.......i havent done much yet but next week i plan on getting a nice header and exhaust kit...... most likely a dyno max and i have b&m shift kit and 1800 stall converter......i havent done much yet but i just dont know where to start 1st

I would start with gear in the rear end. 3.23 to 3.42 are good gears for street. You need to find out what you have and go from there.

would i have to take the rear end apart to figure that out or would it say it some where.....im the second owner of the car and the 1st owner didnt really add anything to the car so im guessing its the stock ratio

Here is a tread talking about decoding rear axle. When it comes to rear ends 507Olds is the guy to talk too.

Not that you will notice. Be aware that there is no magic add-on that will instantly give you an extra 150 HP (well, except for nitrous). You need to buy parts that all work together at the intended RPM range and intended use. The MSD box forms a foundation for other mods that generate increased cylinder pressures.

so your basically saying that i dont really need it until/unless i change my cams???

Cam it only has one. Plus a few other upgrades like higher compression pistons, heads worked, and so on.
