can you use the cast manifolds or do you want hi po ones?

Hey Greg, don't plan on using the cast manifold, just had them handy and thought I would cut them up to get an idea of what I'm up for when I make my own manifold.
Was so surprised when the passenger side bolted in with no problem uncut.
Next week I hope to make a start on the fab work.

[eyepeeler]

Ordered and received the first bits to make the headers. Now comes the head scratching, LOL.
Went for 2" off the manifold, 2.5" after 1st "Y" and 3" to muffler.




Got 1 bit in, don't know how it will go???
Will be tight as a nuns proverbial.

And you need to get 4 pipes through that^^^ gap. Correct?

[eyepeeler]

Are you aload to take the lip of the chassis rail ?
If you are do it makes a huge differance ( pipes & plugs )

  
Hey Kev, not sure if it's ok to do that rule wise?? Wouldn't think so but I do agree with you, extra room would be handy.

And you need to get 4 pipes through that^^^ gap. Correct?

Not sure that will happen, 4 pipes may be asking a little to much. Might have to get the first "Y" up above the steering column.

I'll be watching how you get on with the headers as I'll be doing that at some point. Could you trim the end of the steering column back closer to the bulkhead?

I've buit a few sets of 4 into 1's for LS1's into Toranas, best for two pipes to go in front of starter and then under, and two down the side as you have started. And it helps heaps if you take the outer cover off the column up to the fire wall, gives you more wiggle room.

[eyepeeler]

Used the idea of cutting back the steering column outer. Was careful to cut it straight so the bush and bearing went back in cleanly.





Went back in easily enough. Hooked up the steering again.

[eyepeeler]

This gave me a heap more room. Got a path for 2 pipes to go now.



Doing this, welding a shirt ring in the bend to seat it properly in the flange.


The path for the first 2 pipes.

Got the Motec dash today. Car Porn.

[eyepeeler]

Thought it would be best if I put in the spark plug leads as well, don't need a problem with them fouling with the pipes.



It did change the angle which I had the pipes in at last night.

[eyepeeler]

So gave put in a small offset in the pipe closest to the firewall to get the angle back, and run the next one around the steering column,



Next was to change direction of that pipe to get along the same line as the first pipe.

[eyepeeler]

I'm done for the day!!
Got this tacked up. Pretty happy for a first attempt at exhaust headers.

[eyepeeler]

Gee your a patient man, that would do my head in, do the front 2 pipes come out under the starter and are the back 2 the hardest or should I say tightest fit?

Front 2 pipes I hope to head around and past the top arms.
I have room only just for 2 of the 2 1/2" pipes down past the starter motor and sub frame.

Now for the other 2 pipes

[eyepeeler]

The reason I don't get onto my car is work gets in the way.
Bought a second hand collar maker, pulled it apart and gave it a good clean and splash of paint and reassemble.

[eyepeeler]

forgive my ignorance but what does that thing actually do? I know what you mean about work though!!! cheers greg

That machine makes the metal collar that you see on the sides of sheetmetal airconditioning duct, the collar is used to duct tape flexible duct to, which goes out to the diffuser.

Hey Craig, you might want to replace the cotter pin nylock nuts with two nuts locked together. The heat may affect the locking action.

Do you think a crush nut would be ok Darky? Your right though, nylocs would turn to jelly being that close to the header pipes.
