Extractors to clear RRS and AOD

[lukep6470]

Hi,

So my Hedman shorty headers don't match up to my new exhaust ports at all. The ports are so much bigger they are wider than the mating surface of the headers. I had to goop up the gasket to stop the massive blowby I was getting.

Does anyone know of tuned length headers 1 5/8 or bigger that will clear R&P steering as well as an AOD? The exhaust ports are raised so I might get away with 351w ones.

FYI The existing headers are Hedman 88400 1 1/2 primaries.

You will need to get a set and modify them or get a custom set made. You could go for shorties to help reduce the mods to be made.

Try XY pacemakers but they will still need to be modded. Don't think you will find an off the shelf solution.

I know the Sydney mustang RHD headers are close but need to be modified for racks - might be a good start, Having said that a 1 3/4 primary would be better but do not go smaller than 1 5/8.

Cage is right (when is he not). I have a set of modified XY pacemakers on my Cougar.

Note: Hedmen are a better header.

Its a 347 it really needs 1-3/4 primaries just suck it up and get some made. Exhaust innovations at Capalaba bit over $2k Brian Pratt is the bloke.

I may still have to go custom. I will keep that in mind.

Hedman make a midlength header in their elite series that people have had good success with on 347s. They also look like they will clear everything. PN 88656

Hi Luke
I've been looking at this as well as a I have the RHD TCP R&P setup. Ozbilt, I'm sure he'll correct me if i'm wrong, recommends the JBA shorty's for RHD TCP applications which I think is the 1 3/4" primary/ 3" collector.

I saw a set of Hedman mid length 88656 on ebay at the moment in WA, he says he's selling as they did not suit his RHD setup might be an idea to contact him and see what set up he has and what they hit.

I have a set of Hedman elite full length headers that I am test fitting on mine in a couple of weeks, let you know how that goes which are 1 5/8" primary 3" collector which might be a bit big for my 289 and they apparently hang low. Failing that I was looking at the Hedman 88408's which is similar to what you have with the smaller primary of 1 1/2" and would likely suit my lil 289 better though I'll check my exhaust porting as my ports have been opened up a bit so thanks for the tip.

Hi,

The cool kids also seem to be using these which clear AOD's as well.

[boofhead]

They look like what's on mine. They clear my AOD fine.

I seem to remember that I paid about $650 USD for a set of JBA shorty headers (ceramic coated) a couple of years ago for the 351W into 65 coupe.
As SP has mentioned previously they aren't an easy fit which required specific engine mounts a plenty of BFH to get them in.
By the looks of it, any off the shelf system will be the same, you can take a chance with the ones Summit are selling or get a set custom made and do it right first time.

Cheers

OK I'm really annoyed. I was just about to pull the pin on a set of headers on the bay and someone beat me to it. Now he is trying to flip them for $250 more than he paid for them. ?
