Problems with exaust/fuel lines? Hey guys,
After working on my '69 Camaro with my father tonight, we found that the drivers side exaust manifold does NOT clear the steering box. I am just wondering if anyone here has used the stock exaust manifolds and made it fit? If not so, does anyone have a good set of headers made for the '69 Camaro LS1 with SnP motor mounts? Preferably at a good price? Thanks for the input!
Also, I've got another question. The '98 camaro LS1 is in the car right now, and we're routing the 6AN fuel supply line along the drivers side frame rail. What I'm wondering is this: We cannot find where the return line plugs into. Does anyone have close-ups of their motors, and the fuel lines?
Here's a couple pictures of my exaust problem:
Once again, thank you guys!

I just finished modifying my pacesetters tonight, but i believe that people have said that '99 vette exhaust manifolds will clear the box. Maybe someone else can confirm this. Here's a pic of my modified pacesetters...
If you can weld well, i'd highly recommend doing this. I'm 17 and havent welded a WHOLE lot, and i had no difficulty doing all of it myself, with excellent results. It's just kinda scary when you chop up something you just paid $300 for.
The first two tubes need to be cut at the flange, moved in 3/4 of an inch, and re-welded. Then the collector needs to be carefully cut off, and re-welded straight. also, not difficult. I chopped the crap out of mine, then had to weld 5 or 6 things, but thats all that needs to be done. On the passenger side, i simply torched the bend till it was red hot, then sat on it, and it bent perfectly straight. The drivers' side clears the manual steering box by 3/4 of an inch, and will clear the power box even more. Just a suggestion.
Hooker also offers a LS1 F-body header now, painted from summit they're around 500 bucks.. good luck, someone will hopefully correct/confirm the '99 manifolds.

ooh and for your return-line question, you'll need a 1999 corvette fuel pressure regulator, i found a picture for you, then photoshopped in words that explain how it works...
I hope that helps.. The fuel pump goes to the "fuel in" directly from the tank. ALL THIS IS ASSUMING YOU HAVE A FUEL RAIL WITH A SINGLE LINE IN!
otherwise, this won't work, and you use the return line all the way.

they're 3/8 from what i hear. I have not purchased it yet, but that's what i'm told. I'm running my whole system with -6AN.. If you wanted to make sure, just call street and performance, they'd know what you're talking about.

Thanks for the input, guys!
I've heard some pretty bad things about pacesetter headers, so I'm not sure that's the route I wanna go. Being winter break, and switching universities this semester, I'm getting a lot of hours this winter. Hopefully, I can afford a set of Stainless Works headers...does anyone know of any other companies making LS1 headers for a 69 camaro with factory steering?
Once again, thanks!

Hooker, ATS, stainless works are all i've heard of... And i'm curious what you've heard about pacesetters.. I've heard only great things.. thick flange, great fit... I'm just curious.. If you can afford it, go for stainless material.

for the fuel line hookup... its like this.
imagine you have a return style fuel system.. no rails or injectors, just pump lines regulator and tank.
everywhere on that feed line between the pump and the regulator, is your regulated pressure.
so you can tap into that line anywhere.. at the regulator, on the line, anywhere.. and feed a single line to your fuel rail.
your return line is always hooked to the regulator.
the corvette filter/regulator pictured above is how GM does just that from the factory on the corvettes... and because its a consumable item (it IS the fuel filter) its pretty cheap..

sorry i asked the wrong question. Would the above setup be needed to use the firebird ls1 in a fox mustang using the mustang in tank pump? IE, no regulartor on the rail on the firebird?

it doesnt have to be the corvette filter/regulator, but that is a popular one because of the price.
they're brand new, just came out. I'm sure you'll be the first to try them out. wink wink. They look exactly like my passenger-side pacesetter header, which clears perfectly. Best thing to do would be to call them with the location of your engine compared to the firewall measurements...
be sure to post up with results if you do do that..

here's some photographios...
Here're the new hookers..
Here is the f-body pacesetters, drivers side in foreground, passenger in back..
Here's them on my engine...
Here's it in my car.. note i bent collector inwards, the hookers are already the proper angle...
Couldn't be better fit if they were made for the car.
Got about 1 1/2 inches from the floor, 1" from the subframe..
Oh yeah, i'm running the S&p style mounts, too..
