How many miles did the car have on it? Mine has 140K and it seems relatively good, aside from collision damage.

Those WS6 springs really take a toll on these cars.

Re: LS1 GTA The beginning

Dyno results are in, 325hp 331ft. lbs.

The dyno chart is attached. He kept the timing a little lower because the muffler is holding the exhaust back a bit. And the line is a little wavy because I've got some sort of vibration which is believed to be a driveshaft balance issue. Other than that I think its a decent result for a stock ls1 and automatic

Nope the only time I've had it out of the garage since completion was to drive it around the block to make sure the new(used) axle fixed my wobble problem.

But now I think I'm gonna have to go get some insurance quotes, that should be fun. Is it to late to swap my vin plate with a V6 car?

Yes, was believed to be a bent axle so I changed the axle and bearing. All is good now.

Re: LS1 GTA The beginning

I'm gonna bring this thread back from the dead folks. I sold this car back in early 2012 to help get my life together as I was only 20 at the time. I would really like to find this car and attempt to purchase it back if at all possible.

The folks who bought it from me drove 3 or 4 hours from nowhere Kentucky to buy it from me and that's the last I heard about it. If anyone has any information about this car and could contact me I would greatly appreciate it.

That's a good point unfortunately I didn't document the VIN number anywhere.

Re: LS1 GTA The beginning

Maybe the insurance company you had it insured with can give you some of your past records.
