What exactly does one get for $4000 ? You say good 340 manifolds. What year manifolds, x heads ? Intake ? etc.

It has x heads, cast 4 barrel intake and avs 4 barrel. I'll have to get the part # off manifolds but are the desired 340 manifolds

Magnumswap.com WIth stock manifolds you could lose as much as 20 HP over headers, depending on your engine combo Even 340 and Dakota R/T manifolds Are only a few HP more than 273-318

Are you looking for the 68/69 manifolds or any year 340 manifolds as all will work but some maybe a little more correct for your build. Also the early ones tend to be pricey. $500 to $1000 or more .

Yep, those are 318, not the 340 manifolds. But on a street car I don't think there will be that much of a performance difference.

You changed too many things to just compare the headers vs the manifolds. Everything you changed helped you get the half second.

I put a set of Mickey Thompson Try Y's on my 73 340 Challenger. No other modifications. 9.75's with stock manifolds or open headers. I thought I'd pick up a tenth. Nope.

...for an early 70s 340 will flow better than the mid 70s and late 70s 360 stock manifolds? I have a chance to pick up some 72 to 73 340 manifolds dirt cheap. Since I'm building a daily driver I'm going to ditch these awful headers. I'm not saying all headers are awful, but the ones I currently...
