sb headers, other than the tti or dougs????????????????????????

ok, so i got a full refund from performance peddler for the dougs that i had ordered, and waited over a month for


so now that i got the money back, am contiplating going with a cheaper set of headers, or even manifolds, as i am not building a track car. how will the 72-73 340 manifolds work on a mild 70 340?


please do not tell me that they are no good.

what if.............................. if a given motor is putting out 300 h.p with the 69-70 340 manifolds, how many h.p do i lose with going with the 272-73 manifolds?

and how much h.p is freed up by going with the dougs headers over the 68-70 340 manifolds.


how much over the 72-73 340 manifolds?


thanks for the help
