you want a 5.7 ?

hmm, you must like punishment because damn is the engine bay tight. I envy all of you. I have an LT1 A4 with 3,23's in the rear. With the recent tune it now gets a whopping 17-18 mpg around town. On the highway, it's spinning about 2400-2500 rpm at 75mph so it probably only gets about 20mpg on the highway (estimating)

 

For your engine that's not bad at all. I've got the 3.8 (99) and I'm getting 25 MPG average for city/highway. I do a mix of both everyday.

 

Nice car! Im 16 and I've a silver 95 for a few months. It is a z-28, but it isn't in as good of shape as this one!
