Trading one leak for another is exhausting…

13 Oct

Got the dual exhaust put together and mounted. Fitting and welding went super smooth and turned out awesomer than awesome thanks to Dave from the H8Rcc (of which I am now officially a member). We ran the pipes all the way back, over the axle, between the leaf and frame, and turned them down inside the rear of the rear fenders. Totally stealth. Initially at idle it was loud but still sounded pretty good and engine braking gave me a fantastic Harley-esque burble and pop. Unfortunately, just cruising around it was WAY too loud and pretty much droned like I had a busted muffler the entire time. I partially attribute this to the fact that I have a 3OTT and 4.11 so it doesn’t wind up or down very quickly and partly to the fact that the 2.25″ I.D. pipe is totally overkill for a 216. Drove it around a couple nights and I couldn’t stand it. Acceleration sucked too. Kept stumbling and stalling…turns out I had a massive vacuum leak at the base of the carburetor as well.

So… How to fix the sound? Motorcycle baffles.

Seeing as I already had a big ass pair of 30″ fiberglass stuffed Smithy’s under the cab, I knew I didn’t want to add just another set of glass packs or resonators. I wanted tough, crisp and raspy with out being high pitched and my experience with a warmed over ’74 750 Honda with an open 4-1 megaphone got me thinking about tuning pipes and restriction/choke plates which in turn lead me to Khrome Werks, which is where I discovered their 2.25″ O.D. HP-Plus baffles for Harley drag pipes. After a quick conversation with their tech dept (they design/build everything they sell) I figured, based on the construction (see pics below), they’d be the best solution.
They were. First off, the tech gal was caught totally off guard when I told her what I was doing but she hung in there and offered educated discussion based on my description of the situation and assessment of the issue. Second, the baffles don’t look all that impressive (actually they look a bit gimmicky to be honest) but they are made to take the edge off a loud pipe and they do just that very well. I broke the pipe at the slip fits behind the Smithy’s and slid the baffles in. They were such a perfect fit that I simply flared the edge of the insert with a pair of channellocks and tapped them into place. The 2.25″ baffles are actually Khrome Werks’ 2″ baffles enclosed in a tube which is bumped out to 2.25 O.D. at the ends, I think this 1/4″ choke helps a bit too. Once I had her fired up I could immediately tell that the baffles took everything way down sound-wise but left just enough of the 6cyl crackle. Should get better as the as the glass packs burn out too. In my opinion, it sounds better (less raspy and much less high pitched) than my buddy’s Fleetline with a 235 and long 1.75″ straight pipes.

Time to move on to the vac leak which I solved by cleaning up the intake/carb surface and using a thicker gasket. Now sealed and retuned, she sings perfect idling at 650-750rpm and cleanly revs up to 1500 with no stumble.

…this is when I noticed oil pissing out the copper line that weaves through the block and feeds the rocker shaft. FML.

Packin’ on the pounds…ol’ girl’s got a spare tire now.

Spare Tire Carrier Mounting

Routing the exhaust this weekend so I mounted the spare as best I could. Need to find an original cross bar, one of mine is a piece of angle iron at the moment. Once I get that I’ll blast and paint the main parts and replace the all of the hardware.

Best part is that the extra weight behind the axle brought the rear down a bit making the running boards look more level. Think I’ll still pull another leaf and add it back in under the blocks tho.

Rear end ventilation.

Nothin major. Just cleaned out the vent on the rear axle. It couldn’t have been any more clogged and might be the reason the differential cover seam is always wet.

I know, I know…still need to scrape the grime off. Whateves. It’s keeping the rust from taking hold.




Comparison; Original vs What is sold as a replacement by online vendors. Which by the way, does NOT even come close to fitting the existing threaded hole.


If stickers add +/-5whp each…

…this bad boy has gotta be worth 45-50 easy! That’s mirror polished folks.





Fun Stuff Pt.7

24 Sep

The other day I was laying on the sofa sipping my post-op milkshake (periodontal surgery), half-assedly watching Last of the Mohicans and thinking about how my birthday is coming up. While drifting in and out of a hazy pill induced slumber I thought to myself… I work hard dammit! I deserve something nice! Suddenly, fully alert, I hopped on everyone’s favorite auction site and purchased an NOS cast aluminum Thickstun valve cover I’d been watching for the past week.


Fast forward a few days…
Headed out to install the raw aluminum cover, get everything pulled apart and I think to myself, “Gee, this is gonna be a bitch to clean when it gets all grimy and starts oxidizing. I should probably paint it.” So, I head back in.

The day wasn’t a total loss. Managed to install the Brake Release handle grommet.


Hand signals – As of now, more than just a finger.

22 Sep

Finally removed the old fender mounted turn signals. Ended up having to cut em off. Man oh man, were they crusty.









Dancin’ in the streets!

21 Sep

Installed a front sway bar from a ’47-55 Suburban this morning. Super easy to get on and it makes a huge difference. No more body roll = no more sliding across the bench! No clue why the pickups didn’t come with em’ from the start…at least as an option.






Pay no mind to the gunks and leaks underneath.

From SLAM to kerthunk.

It’s amazing what all a door panel can do. While improving looks it also manages to silence 99.9% of the rattling the door internals do. I added heavy plastic, cut from the bags the frames came in, to the backside to keep any leakage off the cardboard.



Also installed new door handles and arm rests while I was at it.

Vroom vroom braaaaap bap bap baap!!

17 Sep

2.25″ pipe kit and two 30″ Smithy’s glass packs. Goin’ for a deeper more mellow sound without losing the classic straight six rap. 8)



No apples in these pies.

30 Aug

New-ish tires from a friend. 7.50×16 10 ply farm tires are out and the new 6.50/7.00 6 ply Hercules pie crusts are in. Much better for town/hwy driving.

Side note: Those who think the 216 with a 3OTT and 4.11 can’t run at highway speeds… Mine routinely runs between 55-65mph for extended periods without issue. *knocks on wood*
