headers for FE 390 1968
Hi, been a while since I was last here...anyways I need some help. I am having my 1968 Mercury truck 250 Camper Special restored. The guy doing the restoration installed the rebuilt motor and I told him I wanted to run headers and dual exhaust. He then dropped the truck off at Minute Muffler in Edmonton. Well the shop called me and said they couldnt run dual exhaust off these headers because there wasn't enough clearance (regular headers) because of the dual tanks. I'm confused, afterall metal bends.
Has anyone else run into this problem.
Other then changing the headers to the "shorty type" does anone have any ideas?? I am sure this should be able to be done....
I would like to hear from anyone who has the same truck and has run headers and a dual exhaust. hE SAYS THESE TRUCKS WERE NOT DESIGNED TO RUN DUAL EXHAUST????
Thanks guys...this is quite urgent as he has had the truck in his shop for a week!

Dunno how similar your set-up is to the 4x4 high-boy.....but here's what I know....
I found a set of headers (Dynomax, I believe....check my post history....) that have the proper spacing for the engine mounts and the starter....then I just had a local exhaust shop fabricate the remainder....message me if you need a part number, I can look it up.

i have dual headers on my 69. they are hooker headers i ordered from summit. since have had them on i have to hold the shifter up park to start it, but i like them. i wanted stright backs, but they said because of my dual tanks they wouldnt be able to hide the pipes that well, so i have them coming out just before the rear wheel.

I have a in frame tank on my '68 but have not gotten to the exhaust part yet.
But on looking at I am thinking pass side straight back. Driver side would need to cross under the tranny to the pass side. Both exhausts dumping out the same side or cross the driver side one back over near the end of the bed. I would definitely put at least an H pipe in it somewhere to equalize the exhaust going that route.
Now an interesting thing just happened on my '72. Brought it to the exhaust shop and the owner had to make a pipe from the stock exhaust manifolds to my current piping because non of the "Employees" knew how to do it. I was thinking "no employee knows how to bend pipe and put a flange on?".....

I'm thinking any guy that is worth his weight and works at an exhaust shop should be able to figure something out. I already have the headers on and do not want to change them out...they aere a bitch to get on and I dont want to spend any more money...$30K invested already!
When the guy restoring it picked it up he gave me a p[rice of $20K frame off, nut and bolt plus parts and wanted 2 years...well Im way passed that $ and it has been going on 4 years! His excuse is..."well...run into a few problems" are they in the same union as Lawyers I wonder?

Every one I've seen has had the exhaust from the driver's side routed over to the passenger side to get past the aux tank, and then you have to decide what you want to do at the back of the truck -- bring it back over to the driver's side or ??
Find another exhaust shop, any decent shop should be able to come up with something.

I dropped the bed tank on my 1970 250 (it was leaking anyway) Installed long tubes with 3" collector into 2 1/2" welded mufflers and out before the rear tires.
I had to peen the pipe nearest my oem starter. Works Awesome but the next starter will be a micro to deal with heat issues. Use heat shield at the starter and heat tape on headers to avoid this problem.

Sorry I forgot about the C6 A/T linkage issues! Use a cable setup instead of rigid linkage, I believe lokar has it, or run an automatic floor shifter.

i have dual tanks and my pipes are coming off the headers straight back, then just 45 degrees bent out in front of the tires. i dont see why having dual tanks would be a problem. but i do know i am ripping mine out because there is no need for 3 tanks its just absurd to have 3 gas tanks.

Does anyone have pictures of how they run the exhaust from the headers back (dual exhaust) 1968 250 The issue seems to be the Aux gas tank. If you have run into this and have a solution I could sure use the pictures as this guy says he has to see it to believe it.
I really don't want to get rid of the aux tank. It is a 250 with dual factory tanks, with the aux tank between the rails
thanks
