what kind of mods has everyone done to there cars (305 or 350) and what kind of ets do you have

 

If you go look at everyones signatures you'll find some good examples. A better question however, would be specific to you. Like:

"Hi guys I have a 1989 Formula with the 350 and (these) mods. What kind of et's can I expect to see with good driving?"

Anyway - don't take me for rude. This question gets asked everyday tho, and most people won't bother to respond.
