I have a 66 Olds Cutlass 330 4BB 35,000 miles with duals. Thinking about headers (+30 hph)from Kooks (Dick MIller Racing) as they seem to be the only ones who make them. ($595.00)Would that modification take away from the value, or would I be better off finding a correct Posi track rear end for this beautiful car. Or Both?
