View Full Version : Anybody running 289 Hi-Po manifolds?

If so do you have any pictures? I would like to find a set, but I imagine they are pretty expensive.
Isn't there a 351 manifold that is of a similar design?

Right know I have a set of stock 5.0 headers, but figured these other manifolds would flow just as well, and look better.

I think you should clean up the 5.0 headers and continue running them. The HiPo 289 cast manifolds flow well for a cast iron manifold, but they're still pretty restrictive.

Why do you think Shelby opted to remove them in favor of the Tri Y's.KK

I had a set on my fairlane they didnt feel that good,I noticed power increase when I switched to headers. you'll gain speed by not adding the weight.

I've got them on my '66 Mustang, but I haven't got anything to compare them to regarding power.

The Mustang houses all carry repro's of these things for under $300/pair. NPD (local to me) has them for $275.

I don't have any pics, but every Musang parts catalog I've seen does.

Go here http://www.nationalpartsdepot.com/catalog/mustang/mustangcat.html to download the catalog, they're on page 89.

The originals are prone to cracking. Stick with the headers. The 351W manifolds seem to be better flowing, but still not on par with a header.
