Last 2 mufflers in the video.
It's a noisy 502 BBC , I can tell its its Comp Cams XR274 Hydraulic Roller cam equipped, what they sound like Comp Cams super noisy clatter from the the valvetrain.

I heard they were decent honest guys that did good work. The internet reviews were all good. I was floored over what happened but it could have been worse, a bad job on top of over charging.

Grumpy’s should get a percentage from the retailers for the sales generated by us. I’m sure I bought Everything you ever recommended to me over the last 12 years Brian!

I just bought a conversation kit early this morning for the Cat. I’m swapping over rear disk brakes for the drums. Got a Detroit kit.
New front wheel ABS Hubs for the Avalon. A Motive oil pump for filling Toyota transfer cases, motor oil and transmission fluid (because they don’t have dip sticks).

Well at least I don’t have to cut any welded mufflers, my SS bands saved some trouble. This is another time when buying shit and shelving it for years comes back to bite me on the ass! Walker has a 90 day satisfaction guarantee on these mufflers but no good now. Wonder how much could I sell these “Used less than an hour mufflers” for?

Probably 75-80% new value now.

My list of things to do on that Cat never shortens! Waiting for some cooler temps to come, I get more done in less time and don’t feel so wiped out before I’m all done.

Still need that new steering column installed.
Driver’s door hing repaired.
Wipers are too tight to the hood (That’s another post)
Washer lines with squirters installed.
Install a puke tank for the radiator.
Install washer reservoir
Added today
Rear brake conversion
Convertible top problems fixed
Install new mufflers

Still to go
Find AC compressor and install with additional AC parts.
Repair lower rear valance.
Repair front lower valance
Find out what’s going on with radio not working.
Set idle speed
Timing
Read spark plugs
Remove the fuel filter just installed.
Find a OE air cleaner for a Pontiac QJet
Install new shocks

It's best to plan out days to work on the Catalina .
Looking at the list some projects require 1-2 days to complete.
To get stuff Done I have to ignore all else going on.
Phone set down or shut off.

I thought Recessed Hidden Windshield Wipers were 1st used on the 1970 Trans Am.
Looks like your 1968 Catalina Convertible has hidden Recessed hidden windshield Wipers.
The Wiper motor, transmission linkages, and wiper arms with Trico Anco Wiper blade Refills are special all for hidden recessed windshield wipers on GM Cars.

The Wiper arms on the 63 Pontiac Gp one failed stripped out back in 2011.
Hard to find but I found and bought a nice used set from an ebay seller.
Can only find used not reproduced any for my car.
Wipers sweep outward away from one another like a C4 Corvette does and back in together running in
the rain.

I have to provide pictures but when I look down the windshield standing be the driver’s door I see the wiper arms touching the underside of the hood. It’s a very narrow space. I’m thinking of a couple things. There may not have been that much space to begin with so if the hood went un noticed from a past re install and it sits just a 1/4” lower up by windshield and perhaps wiper blade refills are a slight bit taller, that could be enough for interference.

I have no idea where to begin trouble shooting the convertible top.

DynoMax Super Turbo mufflers will be delivered tomorrow, yes, on Sunday!
The part number you gave wasn’t what I needed. Had to order WT-17733, off set and center outlets. $45.88 ea. Delivered by Amazon. Expecting a bunch of goodies today too!

Really need an OE air cleaner. Somewhere somebody threw theirs in a scrap pile because they preferred the open element chrome lid one from Pep Boys.

It's been a long time since I troubleshooted a convertible top power motor system on a Vintage Musclecar.
A good place to start is right at the Convertible top power motor that turns the hydraulic pump.
Feed it power direct.
Or use a test light on the connector to it.

You want the GTO 400 HO and 428 HO 390 Hp Dual Snorkle Air Cleaner.
I don't want to sneak back onto Facebook to get onto the Pontiac Groups.
Everyone knows me Nationwide and Worldwide posting for years and sharing videos and pictures of my own and doing Restoration and Full Race Tech like here on Grumps.
Really Hate Mark Zuckerberg.

A few Pontiac groups I found on Mewe I am in. Some days active other days notta going on.

Really dismal Facebook none of car guys will leave it seems.
I haven't seen anyone posting from FB onto You Tube lately thier own Channels.
Just Darin Morgan teamed up with the Drag Boss.
I haven't seen My Friend Chad S. Post make any new videos for 2 weeks unlike him.

Brian, the last owner replaced the motor for the hydraulics. When I bought it the top was very slow and he said the system needs to be bled out. A Convertible Corvette is easy access, I don’t know how to get to anything yet.

I’m hoping I don’t have to cut the exhaust for the switch over mufflers. The new Supper Turbos are 1.9” longer.
Amazon screwed up, they charged me for 2 new mufflers, but when I reviewed my order email they sent, it says one will be delivered tomorrow. I contacted them about their error and their way to fix it is to cancel the delivery, and they will reorder 2 at the same time, expected delivery now is for Monday. I don’t know what’s going on at Amazon, many of my orders are not delivered on the day they state. Waiting for the delivery that day I have to check my email to find a last minute change. Normally I wouldn’t care, but when I’ve got a car apart and ready . . . .
