It fits...sorta. Help!

Roundbodies are tough for Headers :

Hookers:

No room to move them either. Starter / Center Link tight.

W/O Starter - Idler arm btwn tubes and frame rail - middle center left:

Starter clearance?

Amazing engineering...

It doesn't hit anything now ...

Yeah that's another good option. Cut the collector off and re-weld it to move the flange somewhere that works.

Offer still stands.

this gets my vote. Are we voting?

Only if you are deceased and/or an illegal alien

8) can i vote too? i dont mind dying again

Bort, I might need to ask you some... favors? =)

I weld for beer and/or sexual favors.

I think you had better stick to beer tho

 

[michael_cini]

yeah, i would definitely stick with the beer

OK, this seems to make the most sense. There is only one problem, once I torque down the head I cannot get the header in or out of there. So, do I have a shop weld an extension on after I install or before?

You can't move the header once the head is torqud down ?

Sounds like the entire header could use some tweaking.

 

[michael_cini]

it can be moved around a bit, but not removed from the engine bay. not enough clearance.

Well, I wouldn't want to try to re-weld it in the car.

I don't know what kind of headers you have but mine are Clifford and I don't have any clearance problems. I take them out once a year to paint and put them back in with no problems. The only clearance problem I had was the starter wire stud and I put a ding in the header at that point and I have a 1/2" clearance now.

If I have a starter problem I will probably have to remove the headers to get at the starter. About a 15-20 min. job.

i have a 250 transplanted into a 63 falcon. its a bit more challenging.

8) i should have noticed that earlier. that then is your problem. you have headers designed for a high mount starter on a low mount starter engine. you might have to redesign the header somewhat to make it fit.

 

[michael_cini]

i have good news to report. i had previously test fitted the header on with the log head and i could not get it in and out of position without removing the head. yesterday i got the OZ head in place and tried the header and i can now get the header in position and out of the bay with the head on!! i'm thrilled. i now have the cylinder head torqued down, but i will still have to modify the header. the next step is to remove the header flange and add an extra length of pipe and i will be good to go. the process continues...

can I vote? I am in Florida so it wont count anyways..... :deadhorse:

One fix that nobody has mentioned is this.
Make a"piece of pie"shaped cut in the collector.Bend collector away from the frame.
Reattach the cut out piece,anong with a filler piece to close the hole.
Seems pretty simple to me.

[michael_cini]

still had to do 2 pie shaped mods after this to clear the frame rail. but now it fits!

 

[rbohm]

8) nice job.

 

[LaGrasta]

Maybe I haven't been following along closely enough, but I don't understand the whole "pie shape" idea. At any rate, the piece looks killer!
On top of that, the recent Car Craft just did a dyno report saying how an extended collector (like you show in the picture) added greatly to hp. In their test it was something like 30 hp!
You may have unknowingly added a lot more "thump" to the Aussie 250 beast you are building.

 

[michael_cini]

Thanks for the advice LaGrasta, glad I'm doing something right...even if it's by accident!

I have made a crude illustration to show you how the pie shape weld works.

 

[LaGrasta]

got it! thanks.

I got to get up to your place soon and check this out first hand. This is going to be a killer powerplant!

 

[michael_cini]

i certainly hope so. i am hoping to do the start up this upcoming weekend. but i'm still waiting for the carb adapter from mike.
