can you put headers on with the engine still in the car?

 

of course, long tubes i belive are the hardest to put in but can still be done with engine in the car. When you have trouble getting a side in just take a motor mount bolt off and torqe the motor to one side with a jack and a peice of wood. Make sure to have the car high enough so that you can angle the headers if they are long tubes, those suckers are big.

 

I agree. LTs are harder but I didn't have to jack the engine up. Thank God!
