Default Silver Lake exhaust restrictions

I have a decent mildly built 390BB and a 4 speed in my mud truck (66 F-100) with true duals and glasspacks. Last year @ SL i had a glass pack fall off one side, so I removed the other glasspack, put about 3 feet of straightpipe in and finished the weekend. They didn't say anything.

I would like to do a header flip on my truck and am wondering if anyone has had any luck putting the exhaust out the hood or altering it so i dont have the exhaust in the way when i need to change my starter (review info below for details). I'm not always @ SL, but would like to easily make it park ready.

Details: The way those FE motors are setup the aftermarket headers completely surround the starter. In order to change the starter the header has to come off, in order for the header to come off the motor mount tower has to come off, this attached to the coilbucket. Long story doing a starter takes a solid 5 or 6 hours on a good day (the truck is 45 years old). I have a feeling the header heat and a good 4 or 5 days on the dunes is going to consistently blow starters. Header wrap is a quick fix if i cant find anything else.

Any ideas, thanks.




I have 2 good hoods and one junk hood for this truck, so hacking up the hood is not really an issue.

Summit sells starter heat shied blankets for cheap and they work.

Yeah, and headers thru the hood just scream redneck. Don't mess up a nice truck like that.

I know, but i use it too much. Im collecting parts to build another one, almost identical with a 7.3. That one will be much more "non redneck".

i would just like someother exhaust options without going back to stock manifolds.

Once you poke the exhaust through the hood your now 'above the radar'. Meaning you might have met the sound requirements with glass packs under the truck but once you put them in plain sight, your going to be asked, 'where's your spark arrestor'? No spark arrestor, you will most likely not get in the park, simple as that. Regardless of how quiet you are.

Thats real helpful, did you bother reading my post or did you just post out of habit?

I'm trying to figure out how to route the exhaust so the starter is accesible. That wrap thing looks fine but will be a PITA getting it off after bog. And changing the starter will still a few day job.

Or get rid of the headers and go back to exhaust manifolds..............
I've never been a believer that headers do all that much for a close to stock engine except add noise and heat.

What about custom headers through the fender well and run the pipes between the frame and rockers?

Couldn't you fab up some sort of sheet metal heat shield for the starter? It wouldn't get wet/hold mud the way wrap can, and should help some.

As for the through-hood exhaust, it's conspicuous white-trash stuff like that that gives the off-road community a bad name. Even if this truck gets trailered, many a soccer mom rollin' her minivan and lots of neutered guys in a Prius that sees it rolling down the road will make a mental note that goes something like this: off-road = white trash = destructive to environment = shut down trails and access. This stuff, along with noisy ATVs (or more accurately, ATVs in general) and noisy dirt bikes and obviously home-brewed Jeep modifications, does tremendous damage to our cause. Sorry, guys, but it's true - there are more of them than there are of us, keep that in mind.

Although i understand that a little. But i would rather educate the public a little as well. That being said a truck on 44's still gives off the same vibe.

Personally, i;m not to worried about what a bunch of liberals think. I'm beyond trying to impress them. They fukc me over everyday with their president, least i can do is piss them off a little.

Those starters are notorious for shitty remans and shitty fresh ones. Notoriously blowing for no reason.

My real problem is when i do use the truck i have a lot of time and money invested into the trip. Multiple hours away, 4 to 7 days off. A starter failure= weeks over, put it on the trailer and look @ it.

Anybody have any good pics or suggestions of who to go for to find custom headers.

Spend some time and money and have a set of good custom headers made to go out the fenderwells. I will guarantee you will not make the second gate at SL. Hell the way things have been going you might not make it through town. Or put the stock manifolds back on and deal with it.

This is not a bad way to go, but you will could possibly limit your steering range of motion. On my 79 f250 with fenderwell exit headers I had issues with the tire contacting the header, the truck wasn't lifted and had 35's on it but even with a lift it still may hit.

Check out Jeff's Bronco graveyard for a few affordable header options. otherwise find manifolds for it.

a friend of mine runs a s10 on fullsize frame with headers through the hood at silver lake all the time with a very healty bb (700+ HORSE). All he dose is bolt on a set of flowmaster mufflers on never had trouble with cops not sayin that he wont thats just what he does. I would go the custom header route myself but to each his own thats just my .02. By the way nice truck for a ford

Not sure the layout around the starter but could you use something along the line of a slip joint with a spring or bolt to make a portion of the tubes or collector removeable to access the starter?

It is said that these FE's really have trouble in the exhaust manifold department. Many people suggest the first thing to do is to swap manifold due to engine design.

Thanks for all the help, kevinr i'm interested in what you are talking about. I just took some pics. I will try to post them up soon.

Sounds like custom headers are the way to go, i will check Jeff's any other suggestions
