lbody headers...

Well the time has come, and I have been planning on making some l-body headers for a while and a couple of the members here have stepped up to the plate so this can become a reality!

MY91GT(Z) has sent me the modified headers he bought from johnnymossville.

Sorry 91GT, but being sick last weekend, all I did was lay in bed

So. I have the headers here at the shop now, and got them bolted to a spare block and heads I had here. Come to find out the headers I started tacking together were on the right track! A little different in the routing, but the primaries were almost in the same exact position.

Now, I need more help from the Beretta/Corsica owners. The S&S's are still standing quite a ways off the front head and appear to me that they won't clear a stock fan. Can someone measure the distance from the fan motor to the front head where it meets the block (maybe even a pic)? I know loner's turbo headers I built used exactly 1/2 of a u-bend (about the same as the S&S), and we had to swap his fan out.

I might take some pics with my cell phone, but really would rather wait till I have my wife's digi with me (mine crapped the bed).

Here's what I had started a while ago...







I'm looking to sell these for about $500-550 coated (maybe via Ben's store).

Stay tunes for more pics. Today I am cleaning up the welds and getting all the measurements taken, and will probably start on the jig to make them consistent

PS. I'm the guy that made Loner's turbo kit

I have a set of headers that need to be re-made that for sure fit a 5-speed V6. They have just around 30" primaries and fit all under the hood with a crossover and all.

They're about 17 years old and age has taken it's toll on them, but the design looks to be killer.

S&S will not clear the "older" fans (mine is a '92), but I just cut off one of the 4 spokes and it's fine, and still seems plenty strong enough.

I "think" the newer fans, which are narrower are OK.

And the wider bend is probably preferable as to air flow.

You are going to have to watch #1 (Passenger side rear) for clearance on a 3t40. There is a hump on the trans that doesn't present itself on a 4t60e or 5-speed.

do you have pix of them cliff

[Cliff8928]

Well, this pic is from the original owner/creator of them when they were new...


I can snap a couple more of them from all angles though.

Whose were those? Those are some nice long tubes... They fit and clear everything?

Look closer at the coolant neck...

What about it? These were originally on a 2.8

[IsaacHayes]

Were those Norms?

[Cliff8928]

Nope, got them off a guy in Canada who sold them on here.

MY91GT(Z), again, I am sorry about the delay, but opening a new shop took 2 weeks out of my life

Here's what I got as of about 20mins ago when home...

That's pretty nifty... One thing I would suggest, if at all possible, shorten up the length of the rear header because I know it drops down almost too low... You should mock that in a body to see how low the bend after the collector is, and you may realize you have 3-4 inches you can work with as far as bringing it closer to the tunnel. I know mine is low, but I got it high enough to not rub... Eric, and Eric didn't do all the same collector modifications I did so theirs are a little bit lower than mine, it was something I couldn't do not having it in a car.

What set of headers was that?? wondering who modified them, looks just like all my cuts but I know where the three of those sets I did reside.

[woody90gtz]

They were from "johnnymossville".

This pic shows how much higher mine could be... although I did chop them and weld on my own flange, so it may not be a good example for you.

[Asylum]

Agreed! Mine could have been about 3" shorter and would have given me alot more clearance. And an not so severe bend to mate it all up.

[3X00-Modified]

I ended up pretty good but that was because I chopped up the collector to make it bend more... I'm surprised the exhaust shop didn't do that for Eric, and I'm surprised Woody didn't try that.

After I cut up the collector and then welded on the chop of the 45 pipe, it made a good bend that ended up working well... It touches the sway bar when the car is in the air, but its got about 1/2 to 3/4" clearance when the car is at ride height.

In my Header modification thread you can see what the header itself looks like.
