I plan on taking on it trip next weekend. So if I got 30+ MPGs that would be great.
With the ported heads and plenum this car pulls harder than it did, but it still could use more power.

94 olds vert: that car is by far the best looking gp gt coupe I have seen in a long time even including the '97-03 models too. Keep up the awesome work!
