RE: comment: gas mileage on your lt1/ls1
i have an 86 tpi 305. i get 13.5 mpg going to school/work as well as cruising and street racing. if i take it slow and drive carefully, i get about 10 mpg. no lies. for some reason, its more effecient to launch hard and then let it coast for about half a mile to let it get back down to the speed limit.

Our Camaro gets about 14 mpg cruising around town: it has a pretty rough idle and sort of just pours fuel through to keep itself running at low speeds. On the highway it gets about 26.
The vette (C5R is just basically a stroked and bored LS engine ) is quite amazing: despite the 427 cubes, the SCr, etc., it gets 21 around town and 27-28 on the highway cruising at near legal speeds (say 75) with the AC on.
But our milesage champ is the Porsche, which averaged 30.8 mpg on a recent short highway trip (Raleigh to Charlotte and back): not bad for a 175 mph performance car with an auto trans.

Highway 101 is on my way to work. I would be lucky to get 15mpg, even on highway. It sucks. Something is wrong with my car, idles rough too. Any ideas?

I recently checked my mileage on the freeway and did quite well.
Car is stock except for being lowered and having a Flowmaster catback.
Pretty sure it has 2:73 gears and I am running fairly skinny and hard Goodyear 225/50/16 tires.
I pulled off 29 3/8 mpg @ 65-70 mpg rolling up Interstate 5.
'93 LT1 Z28.
