340 exh manifolds?

[titanium]

I have a 340 that's going into my dart this winter and I'm looking for some exh. manifolds. ? is are the 68/69 manifolds any better then the 72 and up 340 manifolds? I I have a chance to buy either set. Is there much HP to gain with the earlier set?

It's 68-70, 71+
It's mainly the pass side everybody wants.
That said, a set of Doug's headers or TTi headers would be better then the stock 340 manifolds.

You won't see much difference in the stock exhaust manifolds. My suggestion, save some money and get the right 72's.

If going headers, dougs and tti are the only long tube choices that fit well. They will outperform the stock exhaust in almost ever case.

Thanks for the info. I think I'm just gonna use the '72 set.
