Currently looking at 2 22zx's to purchase, one having a 496 HO with bravo 1, the other with a 350 magand Alpha one drive. Can anyone tell me if there is a huge difference in performance? What are some pros and cons of each? I read somewhere here to stay away from Alpha drives, yet that was for a big block...just a little confused. Want to get this right. New to the zx and the Donzi experience!
