1972 340 testing by Nick

But there are good headers today that fit, don't leak and don't hang low. There's really no downside to running them except for the cost (and I sold the 68-70 manifolds in my two Barracudas for enough to pay for TTI headers).

I went with TTIs because the 340 I finally got didn't come with exhaust manifolds at all. My choice was paying a small fortune for stock 340 manifolds or paying a small fortune for shorty headers.
