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

Re: LS1 GTA The beginning
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?

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.
