Q. Tony,
The driveshaft in my Camaro failed. Upon cutting it apart, I found cardboard tubes inside the metal driveshaft. Have you seen anything like this before?

p.s. I noticed a "restored" Pro Street '69 Camaro listed on the big online auction site the other day. I had a good chuckle as I recalled your Resto Shop article about people calling modified cars "restored" in the September 2013 issue of Camaro Performers.

Cardboard Tubes 2/4

A. Bill,
I have not personally seen the inside of a driveshaft before. Your picture was a surprise to me, so I checked a few sources.

Muscle car restorer extraordinaire and friend Brian Henderson of Super Car Workshop has cut apart many older driveshafts to salvage for restorations. He sees the cardboard in all of the old ones he's opened up. Upon further research, I found out cardboard tube inserts are used in many driveshafts, not just older units.

The cardboard tubes are used to reduce noise generated by vibration in the drivetrain and directional rotation changes. The sound amplified by an undamped driveshaft can be described as "pinging" or "singing."

Thanks for the laugh! I saw that fully decked-out back-halved and tubbed Pro Street Camaro that was promoted as "restored." It was everything but restored.

Q. Tony,
I can't believe the wasted ink on this [incorrectly using the term "restored" for a modified vehicle] subject. Is it being used in the correct way or being used too much or not? Give me a break. This sounds like a conversation the folks at Pebble Beach might have in the clubhouse, but hot rodders or muscle car guys? Have the Camaro fans become one of "them?" What's next, champagne and a string quartet? I live in California, and most of the car guys think the car guys here wear skirts. So if I have to point this out, something must be wrong. So come on folks, stick your hands in a bucket of gear oil, uncork your headers, make some noise, and grow a pair.

Kindest regards,

A. Ed,

Thanks for your letter. Some people might see the word "restored" misused more than others. Or, maybe some are more in tune with it than others. It's kind of like when you never see a blue IROC on the road, until you buy one ... then you're more in tune with them and see them everywhere. It seems like the misuse of the word has gotten worse over the last year or so.

As you read above, two days before you emailed, it happened again. It's not a huge deal, but still.

Hopefully this is the last ink wasted on the subject.

Q. Tony,

Are there any aftermarket LS-style heads available for Gen-1 Chevy small-blocks? Also, my Camaro got stuck in the mud the other day. My 700-R4 transmission got so hot that it melted my shift cable and the oil pan burned me. Once I got the car re-established on solid ground, I pulled the pan to check for telltale signs of destruction. The fluid was still translucent red, no burn smell, no metal shavings, and virtually no loss of viscosity. The car is almost ready for the Camaro Performers magazine Readers' Rides section, so be on the lookout.

Happy trails, friend.

A. Chris,

The only thing I've heard about how to install LS heads on a non-LS Chevy small-block engine is to buy a World Products Motown LS block. It looks similar to a non-LS small-block but has been cast to accept LS heads. It also accepts small-block accessories when additional adapters are installed. Other than that, there doesn't seem to be a better alternative on the market.
