'72 K5 - Greg's @MightAsWellK5 Build

This is the build description. I will improve this later. (GB)
Overview Gallery Discussion
Very true! I thought that was a given but it should be stated.

Want to hear something stupid, earlier this week I was firing up the TIG again to weld some stainless exhaust and I couldn't figure out why I wasn't getting any gas flow. I had a new regulator I only used a couple times, so it was suspect. I coudn't hear the gas flow so I had this bright idea to hold the TIG torch closer to my ear and tap the pedal to listen for the gas flow. :doah: High frequency arcing onto your ear is not exactly a comfortable sensation. :eek1:

O god! No thank you. In my own moment of stupidity the other day I washed my hands and.picked up the torch to weld something. Still nice and damp I was a way better ground...

And let me tell you the high freq on that new invertec 375 we got will kick your ass!

Typically a shorty header is specifically designed to be a bolt in replacement for an exhaust manifold, which is why they don't make as much hp. The collector is limited to the collector size that the factory manifold was, and the primary tubes are shorter.

Mid length headers typically have a little longer tubes and a larger full flow collector. They typically exit at an angle down next to the transmission right under/behind the firewall. The exhaust then takes a slight bend and heads back right after the collector. These are much better than most shorties but still not a full length header, although for most applications a mid length will probably give you most of the benefits of the long tubes.

Long tubes have full length tubes that promote better scavenging and better velocity in addition to a longer time for the exhaust to cool before it merges in the collector. They typically exit down under the floorboards on most vehicles after making the complete turn down and around the firewall.

and then there is extra long tube headers....these Hooker supercomps are bigger diameter tube than the tubes on the Maiden's 461....1.875 vs 1.75

WOW!

Just saw this on my FB status......





Jonathan Ward (of ICON4x4 fame) just gave me a thumbs up on my header build. Pretty freaking cool!!!! :)

CK1. CK2. CK3. CK4. CK5. CK6. CK7. CK8. CK9.

Wow. 1 & 2 are a smaller font... 6 & 8 are normal... 3, 4, 5, 7 & 9 sit below the line (subscript)

Don't worry Steve.... I'll help you find all the weird bugs that need fixing. :waytogo:

Impromptu "Might As Well" Build update......

With the new PS Header installed I decided to re-install the wheels up front, and reattach the upper strut bolt just to check to see what sort of ACTUAL clearance I would have around the inside tire sidewall...





There was a little bit of room left at full-lock right turns.....





I'd say about a "finger's width"!!! :)

Since this entire header build was being done at "full stuff" for clearance-checking purposes... it seemed like it would be fun to throw some N2 in the ORIs and get the front end up closer to ride height just for comparison's sake:





Obviously, there's nothing to worry about from a clearance perspective! I like that the headers will be completely visible when people peek into the front wheelwells..... I think that's a cool look, and one of those subtle clues that there's a WHOLE lot more going on with this truck than what first meets the eye!!!!

At the risk of adding actual "tech" I will offer the following photos. These are desperate times, and with another 24 hours before CK5 is back online (est.) we gotta do what we gotta do!!!!



Got the extension piece figured out on the PS exhaust. This is the small section that sits OUTSIDE of the framerail and will feed into the muffler...

Same area, from the underside:

How things change! The driver's side cab support that I so lovingly repaired in around 2009 was unceremoniously chopped out of the truck last night, along with a large structural torsion/floor support.

That same part as viewed from underneath. This will look familiar to the "full vert" K5 guys....

And a final shot of the DS area where a header needs to fit. I dropped in a piece of 1"x1" square tubing to represent the steering shaft which is sure to cause me some additional clearance headaches.

We now return you to our regularly scheduled programming (which is mostly poop and fart jokes). :)

Did you just flip us off in one of those pics? :eek:


Other than that, nice progress. ;)

Psychiatrists call that "projecting"..... You are reading hostility into otherwise innocent images. :)

Lol....

Hey @max 02 .... You must have fallen asleep in Biology class. Roosters don't lay eggs!! Guess the "yolks" on YOU...

Looks super cool for sure! How much do you think it weighs more than a regular long tube header?
Only reason I ask...I was thinking about all the stress on the flanges and header bolts.
But its not like you cheeped out and used crap material.
 
I doubt it weighs more than a few ounces more than a typical long tube. Tube lengths are all around 32-36" same as regular long tubes, and the material is stainless which is stronger than mild steel. I can envision the headers having more leverage on the bolts being outboard, but I'm sure Greg will have the rest of the system well supported.
