Shorty headers
 

So I had purchased some of the Dynomax Chevelle shorty headers a few years ago at the recommendation of some on this board. My truck is bagged, and I don't want the exhaust hanging below the frame. Well, I went to bolt up the headers and they hit on the PS motor mount and frame. After some more reading I realized that people w/the '67/'68 trucks have this issue. I know of one person that is running shorty headers on his '67, but he hasn't been on the board in a bit. So my question is, what shorty headers are you guys w/a '67 or '68 truck using? Oh ya, it's a V8....

Re: Shorty headers
 

SBC or BBC? I know on the 67-8's the frame needs trimmed on the top rail to clear the headers. If it is a BBC you need the correct 67-71 mounts to get everything in there, if it is a SBC I am curious? Picts?

Re: Shorty headers
 

I'm running Sanderson headers in my 68 with a small block. No issues at all, very nice header. Early Classic sells a Sanderson set, coated, and a bit cheaper than you can buy them from Sanderson.

Re: Shorty headers
 

They clear the top rail, cool? I have had to trim the rail on every one of my 67-8 with headers as it seems most headers are made to fit the 69-72 but are listed as 67-72. Any picts? BTW are they shorties or full length?

Re: Shorty headers
 

It's a SBC. Don't have pics cuz I've already boxed the headers back up.

Thx for the heads up Fastom. Since those are mid-length headers, do you have any pics of how low they hang?

Re: Shorty headers
 

I seriously got tired of trying headers for mine and ended up with old corvette rams horn manifolds and where the exhaust tube drops out, I took it immediately to the outside of the frame rails and down the outside into the mufflers just behind the cab and dumped down before the axle. Now my exhaust cannot be seen from the side and no where does it hang below the cab or frame, allowing me to go lower.

Re: Shorty headers
 

Pictures!! Here it is.

Re: Shorty headers
 

Fastom,
Any spark plug issues? Can You run a standard length plug or do yuo have to use a shorty?

Re: Shorty headers
 

Not a single issue! Standard plugs.

Don't make the mistake I made with these headers, don't use gaskets. I had to take them back off and use only black RTV.

Re: Shorty headers
 

You don't happen to have a pic of the other side do ya? Looks like you were using copper gaskets, I'm surprised they didn't work. Edit: Just read they have a "leak free" flange. Interesting... Oh and the pic on ECE's website is different from your headers. I wonder which is the "new" style?

BTW, nice job on that engine, looks great!

Re: Shorty headers
 

Pictures of both sides.

Re: Shorty headers
 

Wow! Those have tons of clearance!

Re: Shorty headers
 

I'm running a GM ZZ383. This engine has the Fastburn heads. I ordered headers from Sanderson for the heads, angle plugs, and "D" ports.

Re: Shorty headers
 

Now that's the way a set of headers should fit & look. Why don't the other big name companies out there do the same??

Re: Shorty headers
 

Dynomax 3/4 length Chevelle/Malibu headers on mine ... no issues at all, bolted right up and don't hit anywhere.

Re: Shorty headers
 

looking to sell??

Re: Shorty headers
 

thanks Shane....i'll look into those. Looking to change out my Hedmans.....Would those be for 64/72 Chevelle??

Re: Shorty headers
 

These have 1.5" primaries, correct?

Re: Shorty headers
 

I run Flowtech headers I bought from Summit Racing. Flowtech 31500FLT These are ceramic coated, full length, 1 5/8 with 3 inch collectors, and I did NOT have to cut the top rail on either side. It evens fits where my Z bar goes across. I use standard plugs but I had to modify a 5/8 socket to fit #7 plug.

Re: Shorty headers
 

These are the ones I have atm. Dynomax 86118: Cerama-Coat Shorty Headers for Cars with 283-400ci,Camaro, Z/28 1967-69, Chevelle/El Camino 1964-88

Re: Shorty headers
 

Those are the same ones Riveted1 that I'm using ...

Re: Shorty headers
 

I called Summit and they told me these have the 1.5" primaries like the shorty Chevelle headers that Riveted1 has. That's probably why these are fitting so well. It looks like the only shorty header with the bigger 1 5/8" tubes that will fit with no mods is the Sandersons by ECE. I need headers bad!

Re: Shorty headers
 

I wonder why mine hit then? Maybe I'm just an idiot and am not sliding em in just right. Guess I'll go try again tonight.

Re: Shorty headers
 

heres mine summit block huggers ceramic coated ($200) they fit great with no problems

Re: Shorty headers
 

A lot of great information on here...and some beautiful engine bays :chevy:

Re: Shorty headers
 

Those block huggers look nice and the price is even better!

I went out there again and tried to get those things to fit. There's no way. They hit on the motor mount and the frame. Even had a buddy look at it to get a second opinion. Took some pictures, but b/c the frame is black, you can't really see what's happening. Oh well, guess it's time to buck up and stimulate the economy!

Re: Shorty headers
 

I have these same headers and they fit well except for the spark plugs. A standard plug puts the spark plug boot very close to the tubes on #7 and a few of the others. Mine only have 1 1/2 " primary tubes. I have expensive wires and don't want them burned. (Moroso Ultra 40). I have the coldest shorty Accel plugs I can get and have to go colder still. Unfortunately, this means a standard length plug.
I am looking for a set of new headers that will allow standard plugs w/out burning my wires and wont break the bank so to say. I am not opposed to trimming my frame rails and my truck isn't lowered, but I want a "tucked" exhaust system too. I'll probably go with the Sandersons and stimulate the economy as well.

Re: Shorty headers
 

I doubt this will matter, but fastom's frame is the narrower rails. The 67-8 is pretty thick on the top rail and there is no notch in it. We need to see picts, because if these exact headers fit one truck, then they should fit them all. A picture might help us, help you, maybe we'll see a simple something that'll make it work?? Please don't take this wrong, but is it possible the frame mount is on the wrong side? I don't think you are a goof or anything, but I did this myself once, I got them and put them in without really looking? Just a thought??

Re: Shorty headers
 

i will just send ECE my checks every week. i think i could follow them to give me what i need.

Re: Shorty headers
 

Yep 70rs/ss, you are right. Fastom does have the narrower frame. Good eye! I can't believe I didn't see that! Oh wait, yes I can! LOL

Anyway, not sure about the mounts, anything is possible since the PO installed the engine. He did some interesting things on this truck....

DS mount:

PS mount:

And the headers hit in these locations:

You can see where I could tuck the rear part of the headers in a bit more to get frame clearance, but they would just hit the engine mount even more...

Re: Shorty headers
 

Please explain the "narrow frame", I don't understand what that is? The frame on my truck is a 68.

Re: Shorty headers
 

What I thought he meant was that my frame is wider at the front part of the engine than yours. And MY truck may be a mutt. I would not be surprised. This is what my PS frame rail looks like: (I put some white styrofoam behind it so u could see better)

http://i42.photobucket.com/albums/e3...844Resized.jpg

In the pics you posted, it doesn't look like your frame has the wide part and then the cut out. It just looks narrow and straight. But it may just be that I can't see the frame in the pics too well. I dunno.

Bah now I'm all confused :fry:

Re: Shorty headers
 

Yes? No? Maybe so? :hot:

Re: Shorty headers
 

the frame width could be the difference ... mine is a '70 frame

Re: Shorty headers
 

A-HA!


The plot thickens! Sorry, I visited that Mack Truck thread and couldn't help myself :lol:

Re: Shorty headers
 

here is the link to my header install - not much other progress

Re: Shorty headers
 

Nice thread.. but as you can see I'm using the stock motor mounts. I just bit the bullet and ordered the Sanderson headers from ECE. ECE swears they will clear. Should find out this week sometime.

Re: Shorty headers
 

The best part of ordering from Early Classic is they will make it right whatever happens!! Great bunch of guys.

Re: Shorty headers
 

Well, looks like the ECE/Sanderson headers fit:

Don't have pics of the DS, but they fit fine too.

Re: Shorty headers
 

Yeah the only think I can think of on your's is that the top rail needed to be trimmed to allow the header to clear that and the mount, it could be a couple of things, sorry I am late to the dance, but for that little bit of interference with the motor mount, I would have notched the mount? Honestly the ECE header looks a lot like the other header, except the ECE clears barely? I think I have seen a few guys put a shim between the mount and motor. The other thing I would have tried is that the motor mount holes are slotted a bit, loosen the bolts into the frame and the big bolt to the rubber motor mount and tied to slide the metal frame part of the mount forward to get a bit of clearance.

I am posting this too late for riveted1, but someone else will eventually run into this again, hopefully that will help?? Srry riveted1, I lost track of this thread, on another note those ECE headers look sweet, hope the $$$ wasn't too bad???
