If you not stuck on a trans am, here's a quick Camaro SS for sale: http://www.performance-shop.com/show...ghlight=camaro
As mentioned, there are more mullet heads on P-shop above with experience in V8's (aka instant torque).
LS engines are reliable. I'd suggest getting a mechanical inspection and compression test on any used vehicle.
Good mods for the money: headers, underdrive pulleys, intake system,....www.ls1tech.com has a toooooon of info. If you want to spend $2k, a cam and tune can add 50whp.
I can confirm 30mpg fuel economy on the highway from my LS6.
If you go drive one (or any manual V8), you'll be hooked on the torque and sound. I was 8 years ago and traded in my Integra for a supercharged mustang and have not looked back since.
