ONLY 100LL---the EPA and FAA have mandated NO LEAD in a couple years---I can't wait for that to happen--more problems??

This self serve is only 100 feet from my hangar--convenient--

Gotta love the cowbell!

Thats my "time zone then"! Simple "innovators" of what you all enjoy today! There was little "off the shelf" stuff, until WE tried it and worked! Be it cars, drag rides, Bonny, boats, bikes etc? WE DESIGNED IT! Just another goofball geadhead "with an idea"!

...It didn't really... It was just one of many short lived evolutionary exhaust silo experiments of the 99.8 cu. in. inline of that era. The next step was designing a midsection square shape port, to accept the next generation longer exhaust silo attachment. Quieting the exhaust note was also becoming a concern, in the early 70's.

Mercury had plenty of practice in this, starting with the B motors in the early 50s.

Yup We had a "converted" 20H with the "toilet bowl "exhaust..... I have never to this day heard anything like a well tuned one at near 7 K rpm!!!! What I would give to live a couple of those years again! Gary

The cowbell twister has a sweet sound to it as well...

**lilabner** · 06-16-2016, 06:58 PM

Can't beat 12 pipes on a cat with Merc 800's. They were sweet. Much more so than the obnoxious Mazda rotarys at Sebring.

**2us70** · 06-16-2016, 08:26 PM

You could hear that cat running at Pelican Harbor all the way out at my house in North Miami when the wind was right. An unmuffeled Mazda rotary is indeed the most un pleasant sounding engine ever. To me the Viper v10 isn't a whole lot better.

1969 Stock Nationals at Hinton WVA - full fields of 12 toilet bowls in hydro and runabout echoing off the hills - it was great!
