repo HiPo Xhaust manifold

I'm not sure what that response meant in regards to my comment. I'm actually using a cable clutch for my T5. No equalizer bar here...

Oops - I must have missed the info about the T5 in your post; sorry about that.

The 66-67 part number the NPD sells for the K code pivot is also correct for 65s.

I've had my re-po's hi-po manifolds on for about 3 years. The only problem I've had is the #2 cylinder on drivers side from fire wall, the spark plug is real close to manifold and I have to use a thin socket to get that spark plug in & out. Gaskets are not needed for these manifolds nor are they recommended. I like them a lot. I got a big increase in power, they don't leak and you don't get the tinny sound you get with headers. That was the main reason I went with them.

I have them on a 68 cvt, has an 89 HO with PS and C-4. Guess I've been lucky as they are the 2nd pair have bought with no probs.

It's a core shift problem. It's defective, and should be replaced. That said, I always port-match the exhaust anyway, the stock head ports and manifold matchup were always a weak point in Ford SB performance. Port matching would fix your problem- but it shouldn't have been that bad.

I used a dremel tool and cleaned mine up. I am not useing a gasket like original. Works with no problems. It SHOULD be fixed but I doubt whoever is casting them ever will.

so if i have a set of repo manifolds its just the passenger side that may have to be tweaked ? i was under the impression that both sides had the poor casting/alignment problem ?

[66sprint200]

I only modified the passenger side -- the driver side will work fine as cast. Kinda hard to replace a defective manifold as 22GT suggest when they are ALL cast wrong -- if you wanna believe what NPD told me. Dean

Has this flaw in the casting been fixed?
Has anyone bought these recently and run into this problem?

I have a set on my 67that I'll be removing in a few weeks. They were bought & installed in 1991. They only were used for less than 500 mi. I'll check them out and if they are correct I'm put them in the For Sale section.

Silly me! I intended to spring for the added $250 for hi po exhaust manifolds when I put duals on my 289. Hey better flow and no more noise! So pay $250 to get improved flow from 1/8" mismatched ports?

I got a new set yesterday, they are made by a US company. They bolted on with no issues. I'll take them off tomorrow to get a pic of the bolt holes. Here they are installed hand tight. Btw, purchased them through NPD.

I think the issue was the ports didn't line up with the engine ports.

GREAT NEWS!! Would you care to share the makers name and/or where you got them?

[Caper50]

I got them from NDP, I've been quite busy the past few days but will do my best to get the passenger side off for a pic before I head back to work.
