I haven't taken my 81 to the strip yet but, just by opening up the hoodscoop, putting a smaller lid on my stock aircleaner so that it gets the air coming in through the scoop as well as quickening the opening on my secondaries and bumping the timing to 16 deg initial, I have completely transformed the nature of my car. It now squeals the tires pretty good on the 1 - 2 shift, it doesn't even have a shift kit in it, and it seems to pull comparably hard to my 95 6 spd Z-28. I need to put a boost retard in it before I go to the strip though so I can up the boost a bit. I have my ESC disconnected right now because it was pulling the timing back all the time and with 94 octane I'm experiencing minor detonation at the top of first gear so I've been backing out of the throttle and short shifting it. It doesn't seem to detonate first thing in the morning though - I wonder if the cool moist air is helping it?
