I installed an MSD 6A on my NA KA for my senior thesis in college. Worked perfect, but didn't really do anything. Infact, using the factory spark plug gap I lost hp and torque. I opened the gap to .050" and ended up making a very, very small amount of power. I don't feel that the car starts any quicker or has better throttle responce, but it does idle smoother. Gas mileage has not been tested, but it seemed the same.
If you email MSD they may help you. I sent 3 emails to them during my project and the only 1 they answered was the 1st one about which unit to buy.
