Ok so I curentlly found out I need to change my camshaft I have a friend that took Out a 3.8 engine from his camaro now my question is if I can take out his cam and put it into mine I have a 98 gtp ?

Obvious question would be no.

Why do you need to replace your stock cam shaft anyway? If your going through the effort, at least put something better in. Just my $0.02 on that.

Yikes. Never good on a motor. Thats how I bought my car, with a bad motor, and the previous owner did this as well. (drive with no coolant in it) I could put a garden hose in the radiator, and when it got full start the car, and it would poor out of the engine as fast as the water from the hose was going in. Turned out...water pump was waaaaaaaaay gone.

The lifters/valve train were extremely noisy. When I finally took the engine apart later to build it up from the bottom, it had obviously got very hot by the condition of the parts. Hot enough to seize the motor, and as things cooled, shrunk in size so it was able to run again. bad thing is, the damage was already done. Those parts were toast.

If it got hot enough that it's knocking....then you're gonna need more than a camshaft.

Reptile is right ...if it got hot enough to make it knock you might have more issues then just the camshaft. Also these motor have roller cams from the factory, they are very hard to damage with just heat..it might be just the lifters that are making all the noise.

But before it gave out It didn't get hot or anything but we took off the belt to see If the harmonic bslancer would turn to see if it was the cam and it didn't turn at all so what do yall think I'm gonna have to replace to make sure its running right?

The whole engine.

^ sadly X2 I think your brother in law just bought you a new engine.

You would spend enough time tearing it down to figure out what it needs that it would be worth.

When I built my engine, I built it to race, and to run with/around nitrous injection. Not cheap to build a race engine by any means, and especially not cheap to build one of ours from a bare block. If you have to ask...its too expensive general rule of thumb. But you can crunch some numbers, and do a little shopping trip from INTENSE-Racing.com - Grand Prix, Bonneville, Regal, L67 3800 Supercharged Performance Products.

Getting a replacement low mileage engine and swapping it over would be your best bet. You only have about a 40% chance of a shop getting it right the first time where it lasts longer than 20K miles before its dead again if it was rebuilt. A crate engine from Jasper...I'd keep walking as well, stay far away from their stuff IMO. Seriously though...I would give ED a email/call and see what he has in stock.
