66 suburban 5.3 swap

[moosefd]

I'm building a 66 suburban trying to put the 5.3 out of an 04 Chevy truck into it. I have the motor mounts figured out and I'm gathering up other parts for the swap. My question is and I know it has probably been asked a hundred times will the truck exhaust manifolds fit without doing anything to the frame or do I need to try and find Camaro manifolds or headers? I will only be lowering truck about 2-3 inches so ground clearance isn't an issue.
