Does anyone know how the McCoy -60- s were being set-up at the end of their competitive era?
Thanks.

I have one that was custom set up for me by Franny's chrome service back in the 60s. It has precision aligned bearings, chromed sleeve, properly gapped rings and a "sewer pipe" venturi. It also has a turned down head & fins as per Telford's Top Cat article. It should be a real barn burner but I no longer fly speed and I've never run it.

Interesting... Very nice McCoy.
Cliff Telford won Open C Speed at the 1962 Glenview NATS with a speed of 167.84 mph. Bob Violett won Sr. C with a 152.87 speed.
I started Speed in 1967 with an ex Jerry Roselle McCoy that had some work done by Franny's along with a phenolic laminate rotor and a pressed in venturi. The stock rotor retaining rings were replaced by a soldered brass sleeve to set the rotor clearance. But, the basic design was not changed. Performance was on par with Violett.
I was wondering if anyone had gone to a flat top piston and a squish band head by that time.

Bob, seems to me that guys were starting to punch them out to about like 62's then the Rossi 65 came out and pretty much did the McCoy in , the Rossi was just a more modern copy of the McCoy but with bigger passage ways and a full 65

Right. The early Rossi had a lot of McCoy DNA. I figure it wasn't just a chance step change. By that time one or more tuners likely had built a McCoy that was pretty close. My curiosity has me wanting to know more.
