Re: 48 Burb, bagged, 5.3, 20 year wait
 

Thanks Lower, I think it will be strong enough for the loads it will have. Yep, planning to start at the front and work my way back with tack welds. I need to position the X pipe where it needs to be and work back to it. Then a very short run to mufflers and a 90 out to the flex pipe and running board outlets.

Hey 98 good to see you back. I've been enjoying Betty's updates and I ...for a second...thought I was on the wrong build when Nsane was posting pics. Imagine they will do a great job with the metal while you redo the engine.

My AADD was kicking in and I stopped to look at this one. No powertrain installed and has new paint and decent chrome for $3k. Retired new car dealer had a guy do paint and body. He wasn't happy with result so stopped the restoration. Thinking it is perfect for my next LS swap project.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Great starting point for LS install...possibilities here. CFO green lighting the idea too.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Until I crawled underneath...stupid Midwest road salt rusty truck...yeah it can be fixed and there is probably a bunch of ugly under the new paint. Pass.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

I don't like the idea of you toying with the idea of picking up another project. if I'm going to finish 3rd on the Suburban build off it could really put my strong hold on 3rd place in jeopardy...

The notch looks like it worked out well...

Marc

Re: 48 Burb, bagged, 5.3, 20 year wait
 

yeowch, I love the 67-8 front ends the best too.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Definitely pass on the truck there's better opportunities out there Doug

Re: 48 Burb, bagged, 5.3, 20 year wait
 

One thing is for sure my next project will not be a vehicle from the east or Midwest.
Southern and west cars are just head and shoulders better. The Burb was bad enough but the 56 is just getting old cutting and replacing metal. Not to mention $$$ on trim

Re: 48 Burb, bagged, 5.3, 20 year wait
 

That gave me a smile and chuckle! Truck could have been a good possible to have on deck after the Burb. I think the notch will work too. Kinda copied Old n slow.

They do look good. Yeowch is right.

For sure Val. Eventually the right something for the next build will fall in my lap. Knowing this retired dealer and his cars, I figured this one had to be rock solid before he spent money on paint...nope. Always pays to look.

You and me both Iceburgh. My 48 truck was rock solid and was a pleasure to build. This Burb was decent though not perfect. Next one has gotta be nice. Something like this one...http://ls1tech.com/forums/conversion...onversion.html

I think I asked before, do you have a build thread going anywhere on your 56?

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Notch came out good!

Shame you had to pass the C10, from the pictures it looked like a real nice truck.
Something you would find overhere, then you look underneath....

I think you guys have a lot of space to think about another project, while the other isn't finished yet ;)
Wish I was in that position.....:lol::mm:

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Thanks Kees! We are fortunate to have a lot of space. That is one benefit of living in a rural area.


My exhaust platform idea worked...it's a start. Now to find fairly short mufflers to be able to make the 90 to the exhaust outlets in the running boards.

The pipe clamp shown in the picture came from Stronghands and it worked extremely well for holding the pipe sections being butt welded. Very well made quality clamp for like $38 from Amazon.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

My TIG welding skills are not there yet to be able to tack weld the butt connections. Without going into details, it was pretty much a Three Stooges episode. I was laughing at myself.

So I resorted to the MIG for the tacking needed. That worked!

Now, to put in about 100 hours practice with the TIG...it is always rewarding to learn a new skill.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

looks killer, great jig you made. I bet you could make a set of those clamps rather easily.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

I was just thinking that any chance we could get a closeup of them? they appear to have some sort of roller maybe?

For $38 though I don't think its worth converting a $32 pair that one would already have to make them unless you could make it more of an attachment

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Looks great Doug.....I could have sworn I saw these photos before??? Must just be me.

Nice pipe hanger/support set up.

Marc

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Thanks guys. Yeah 99, you could probably make a set though these are very smooth and stable. By far better than any clamp I have ever used.

Val has a good point and per his request here is a better pic.

Marc, you must have seen the preview!:)

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Wow those do look really slick Doug I will need to track a set down for my future exhaust setup for sure

Re: 48 Burb, bagged, 5.3, 20 year wait
 

You're a handy guy Doug!! :metal: ;)

Exhaust is going to look great!
Nice clamp, never saw those before unfortunalty....

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Nice looking exhaust. I'm not sure but I think your exhaust hanger might catch fire. ;):haha:

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Here you go VS... Strong hand Tools PG114V Pipe Pliers with Large...
Thanks Kees! Me handy? From the man who has custom built about everything on his truck that means a lot to me! :)

Thanks Lower, that's not a hanger, it is an exhaust splash shield..:haha:

Mufflers are on order from Jegs....thinking the run might get too long to make the 90 turn to the outlet. Canning the X would simplify this, though am going to try to fab it out to fit.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Thanks! They're 22.97 at Summit. Definitely going to throw them in my cart on the next order.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Progress is looking great.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Good deal Big. It pays to shop around.

Thanks Chizzler. Kinda slow though some progress.

The mufflers came in and hope to see about fitting them up tomorrow.

Spring here has been so wet there has been zero planting done. One of my neighbors has his equipment ready to go as soon as the fields dry up enough for working.

Iowaboynca, I took this pic just for you.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

great detail work!


can you tolerate an H pipe or are you specifically looking for the x pipe sound? I have read an x pipe makes more hp at high rpm and the h more torque at low rpms. there is a big difference in sound too, the x is more raucous and unrestrained.

here is a great comparison, apple to apple, same car with same mufflers and differing only in x and h pipe.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Thanks joedoh. The 56 has the X pipe and I like the sound. Even though there will be variance on the Burb with much shorter pipes after the mufflers, I am looking to somewhat duplicate the sound.

An H pipe is next up if the X doesn't work out.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

OK, the X pipe set up fits.

The patent pending exhaust support system was moved back to support muffler placement.

Welder series header collector flanges were used to connect the exhaust tip and flex pipe. Same for the 90 muffler exit pipe to the other end of the flex pipe. Thanks again to Bob and Marc for the flex pipe suggestion!

One of the pics shows layout to determine where to cut the 90. And I forgot to include the flange thickness, so I had to cut it again.

Right side is positioned and tacked together. Somehow I didn't order enough flanges, so hopefully they will be here this week. Then I can finish the left side.

Once finalized, some of the connections will be welded and some secured with band clamps to facilitate any future removal. Then a couple hangers and it should be good to go.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Doug

The exhaust looks fantastic...Nice work. Hey in looking at your pics you might want to add a flex joint closer to the headers. I added mine after I noticed I was getting welds breaking from stress cause by movement. My exhaust system in the 48 is all SS and SS can act weird when heated and cooled. I actually have my tips with a rigid mount. I tied to have them with movement like yours but my tips would bang against the opening in the running boards. especially because like you I kept the tip opening as small as possible.

Just my 2 cents, you know what your doing.

Marc

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Looks great Doug. Giving me ideas!! Love it!!

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Thanks Marc and Coach! Me know what I am doing? Naw, making it up as I go and using what I learn here...and I am always way open for advice and suggestions.

Marc, the tips are bolted solid in the mounts in the running board. The rest of the system from mufflers forward is the same as I used in the 56 and it hasn't had a problem with cracking. Could be because the Pypes is 409 stainless rather than the 303? Appreciate the heads up!

Here is a pic of a really nice one I found today in a thread. :) this one is a lot cleaner installation than mine.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

:clap:

way to go idaho!

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Thanks joe...made me :)

Thanks Mark. I didn't think of Speedway and I've gotten good parts there on your suggestions before. I should have thought of them.....and they need to send you referral checks. Always really appreciate suggestions.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Doug

The funny thing is this was my exhaust version 1.0
In 2.0 I added a small SS brace that bolts to the running board mount to keep the exhaust tip from rattling against the running board.

In version 3.0 I added flex joints and I changed the flanges on my exhaust to better match my headers. Third times a charm.

Thanks
Marc

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Exhaust is looking really good!
Don't see something wrong with it?

I like that place for an outlet.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Nice job Doug you got all that to fit together really nice in such a tight place. I cant wait to hear how it sounds. It took some time but I really like your under running board exhaust. Nice touch.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Hey Doug.

I was finally able to make it through all 48 pages of your thread. What a great build! You've done a lot of great work!

Your exhaust looks great! I am starting mine tomorrow and hope it comes out as good as yours did.

Thanks for spending all the time to document what you have been up to.

Dave

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Sometimes it takes a few revisions. Hope my 1.0 works!

Thanks Kees! It might need a flex pipe between the down pipe and the X. I am going to give it a shot this way so if there are problems with cracking, Marc can say "I told you so!"

Thanks Lowers, I think I got lucky that it fit.

Hey thanks Dave! Glad you were able to get through it. It does take time to update these threads...way more than on FB. With your fab skills I am certain your exhaust will be awesome!

OK, it won't win a Riddler award, though it should be good enough for this old Burb.

I don't like the regular style exhaust clamps and yet need to use them on the muffler as the exhaust bends too close to it to use a band.

There are exhaust bands at the slip joint behind the downpipe extensions to make disassembly easier. The butt weld at the down pipe to the extension and the slip joints going into the X pipe will be welded. And the flanges at the flex pipes need welding too.

Re: 48 Burb, bagged, 5.3, 20 year wait
 

Looks great Doug, this should work....
I need to get my x member out to of the attic that I had made for the 48 and see if I can use it for the Suburban...Something tells me it wont but I'm due for a break soon....

Marc

Re: 48 Burb, bagged, 5.3, 20 year wait
 

I bet it will fit like a glove! If it won't work Marc, maybe the Pypes X I used might fit.

Just a side note, the 35 Master coupe I sold just over a year ago is on the road. Owner texted me this. I told him I changed my mind and would gladly refund his money. :)

Re: 48 Burb, bagged, 5.3, 20 year wait
 

So once the exhaust was done I threw the body back on the frame to make sure the tank brackets would fit. Yes, the tank filler pipe will have enough room.

Notice the new shop rollers? The uni-lugs were ugly and a pita to put on.
