Engine balancing use piston ring weights?

Is Traco a previous engine rebuilder? Are you sure they didn't mean 1/4 ounce?

"History of Traco"

Culver City, California, 1986 - Jim Jones, Head Engine Builder of TRACO Engineering, buys the company from founders and famous engine builders Jim Travers and Frank Coon (TRAvers & COon). First Travers and then Coon retire after 3 decades of building TRACO, founded in 1957, into one of the foremost engine firms in the world. Jim Jones, hired in 1979, who helped build that reputation, continued to uphold "The TRACO Tradition" with the many projects that followed.

At that time about half the business was directed towards current race engine technology and engine rebuilds of race cars that were originally TRACO powered. That current technology was integrated into those earlier engine rebuilds and updates. Notable projects included Roger Penske's 1968 Trans-Am Camaro driven by Mark Donohue/Craig Fisher, Roy Woods Trans-Am AMC Javelin and Carl Haas's one of a kind Lola Can-Am car nicknamed Aircraft Carrier. One memorable race in 1992 was at Road America. It was the 20th reunion of Can-Am cars and Bob Lee's Jim Jones/TRACO powered McLaren M20, driven by Denny Hulme, started in the back of the pack. After 4 laps Denny took the lead and went on to win the race. Jim also built the engine for Charlie Hayes McLaren Group 7 sports car now owned by Bill Fraley and rebuilt the engines of the originally TRACO powered Lance Reventlow Scarab sports cars. So it seems that in addition to the current TRACO racing engine program, Jim had solidly established TRACO in the vintage race car engine market.

I'm sure I'd read some articles of what they were "into" that was in the Trans/AM days and they were local, some of use were talking about balance and how close it should be so one day I just called them.

A quarter gram is "what I remember". That was........how? many years ago? Nearly 50, anyhow. I do remember she sounded nice, LOL
