Well, one of the first things I noticed while driving the (new 89) I got, was that it seems to move like it is lighter than the 91 was. I used the mods from the 91 on it and as far as I can tell from the rpms/speed/gear, it has the stock 3.27s like the 91 did.
It just seems much more responsive and feels like it just wants to go more than the 91. I did add header wrap to the lower ic tube, but I doubt that made that much of a difference. It has aproximately 120,000 miles less on it than the 91 did, so I don't know if less miles and engine wear would make that much difference either.
Anyone got any ideas or suggestions why this 89 performs better than the 91 did?
