thats ok then, big dollar headers for a big dollar motor. they are a fantastic header but some people put them on mediocre engines, just throwing money away me thinks.

What pacemakers will fit GT40Ps on E series leads?

pacemaker used to make a header to suit gt50P's on s-series but stopped making them due to low demand. they told me they don't have anything to suit that application anymore.

Guess I'm sticking with the ELGT headers then. |

there are headers out there that are designed for E7's but still work with GT40P's it's just a bit of hit or miss as to which ones do and don't work. I have hi-tech's on my LTD with GT40P's and i couldn't be happier, there cheap and there designed for E7's but fit the 40P's. I have 8.8mm top gun leads with 45deg boots on them and haven't got a problem, although i have billet lead seperators which help and the leads are custom made too be a little longer than stock.

Only spark plug I have trouble with is number 4 cyc with leads and need to loosen pipes to get to plug. Are there any headers out there that you don't have to loosen or remove headers just to change plugs, plus still use original leads with 45 deg boot. If not where do you guys get your leads made up. Mine on no4 needs protection as I've already melted 1 lead.
Thanks Steve I too ran hitech's with the GT40P's - #4 plug was a problem. Heated the bend in the tube & knocked it in a bit with a ball pein hammer - no problem after that. I dont think the Hitech's really suit the GT40P's ( if they are the same as I had on mine) as they were still very restrictive - I dont think they can move that volume of gas. Tossed them & bolted on Pacies PH4000's - gases certainly flowed better but may have lost a little down low. Richie

^^The HM headers I am replacing have a prob with #2 and #5. Could sort the prob out like you did, but need more flow in the end. and banging in some clearance would probably add more flow restriction. If the pipes dropped down an extra centimeter or 2 there would be no problems with lead clearance... sux.

Geez Scaffy, why didnt you say something before? We could just swapped headers and saved an a*** of money on new headers  haha, the HM's I have at the moment are Tri-Y.

Just what I was thinking earlier mate!
One thing to look out for on the De Fillipos is the welds. I've had problems with them leaking from day dot. Had the gaskets changed a number of times, all to no avail. Took it to Prestige and Dom had a look and listen. As it turns out, they're not leaking from the gasket, it's the vertical welds between the primary and the flange. Because they're larger primaries, they have to weld the verts on the inside so there's still clearance for the bolts. It's some of these welds that have failed. I'm yet to get it fixed, just need the time.

Advance Headers make a GT40P INTO E SERIES HEADER.
I have em in my car, I'll take a pic tomorrow and show them. I had them installed when I was planning to use them, glad I still went with the advance headers over Pacemakers, they did great things for the car stock (189 rwhp, e7 heads and HO manifold, auto) and I might be looking towards GT40p heads, or more.

schnoods do you know what part number?
I've had a look at their website and they have E series and AU series V8 headers but nothing specific for AU heads on E series. |

Does anyone know who sells/disributes hurricane headers in Vic, from what i have read these seem to be the go in the old windsors along with a twin 2.25" systerm.
Also when you guys talk about a good twin system, do you mean twin the whole way trough. I get it will be twin from the cats to the diff, but is it possible for to fit twin pipes over the diff and to the back of the car. It seems a tight area where the factory pipes run around the guards and bumper. Could you guys post some pics of you twin systems, im keen to see them?? |
