[Fot] Ignition timing in a TR-4

[toodamnfunky at comcast.net]

Greetings FoT

I am planning to attend the Kastner Cup in August and I'm not sure where my
timing

wants to be at roughly 800 ft above sea level. My only experience with the TR4
is at

5200 ft. and 36 -B 38 degrees BTDC is the norm around here. The car has 12.5:1

compression and I generally use 108 octane fuel.

Any advice for Topeka would be appreciated.

Thanks,

Jim G.
