If I had 8K and didnt need it as a daily driver, that would be in my yard for sure! espec knowing a 3yr warranty on the trans I like to chew those autos up lol

 

I have no doubt its putting down anywhere from 400-425 down. Another friend of ours has the same 6.0 liter in his camaro and with bolt-ons and a tune only he is making 390 to the wheels. The truck has the same motor, with a 244 comp cam and valve-train. Should be a good bump in power over the bolt-on car, even on manifolds.

 

The cars dyno a decent bit higher than the trucks. An easy 30hp more with the smae setup.
Also you don't have full bolt ons like the car just a cam correct? If i'm incorrect please tell me so.
Also you said it has a 80e tranny in it? Thats a little more power off the top as well.
If i had to guess i'd say the hp will be about 350ish if your lucky.
Just my guess.
Oh yeah back on topic. It sounds like a good deal for 8k so i say go for it.

 

Also do you have any 1/4 times with it? Or 1/8 mile times? Just wondering what it's running. That can give you a decent idea of power as well.
