[406Elcamino]

The long tubes make more torque. But the would be a bear to hook up to the cat to keep it legal. My Elcamino came with the 2.41 posi. Iy was a weird combination: 229 V6, 4 speed, A/C delete and the 2.41 posi. No emission tests where I am so roller 406, Muncie M21, Moser 9 inch with 3.89 posi and 2 1/2 duals with long tube headers.
