Not sure if this belongs under 1/2 A, but since that is supposedly for building 1/2 aircraft, I'll start here.
In the very late 40s to 1950, Mel Anderson teamed up with Leroy Cox to adapt Mel's .045 "Spitzy" engine for tether car duty in the all metal ".045 Special" , a Cox Thimbledrome car.
At the end of production, a few went out the door with a hopped up version - the .060 for the purpose of appeasing tether car fans who complained that the .045 was too slow. I know that one of the distinguishing characteristics of the .060 is a taller head; there are three chrome external fins as opposed to two on the .045.
I've scoured the interweb and have viewed several Youtube Videos of both engines running plus Wikapedia results. All informative.
My question : What other engine mods were made by Mel and Leroy to the increased displacement .060 Spitzy ?

Now this is interesting. I have a couple of these cars. I know that they were Spitzy's or similar but never knew about the .060. I'll have to check mine, but don't think they have the taller head. One does have a bit of tire wear so must have been run at some time. looking forward to hearing some informed responses.

The Spitzy was a great no power perfect for sport ff engine. I can't believe that the .060 was much better. It had a fairly long stroke for the day and very tame porting

Glad some of you are familiar with these. After years of ownership, I've just discovered that I have the .060 in my Cox TD "Special" tether car.
What Dennis said is factual. Anything more I discover about this engine/trans combo would be icing on the cake, so keep it coming.
I'm so impressed by the near 70 year old technology to say nothing of the excellent engineering and machining for these miniatures.

I have one of these cars also. Used to watch my dad run it in the garage when we were stationed at Dover AFB in late 50's. I used to run it my self on occasion in the early and mid sixties in Orlando area. been sittng ever since. Need to get it out and clean it up.

Gordon :
Neat memories, for sure. Word is that it is best to run it with the exhaust lever slider in the closed (quiet) position.(Hopefully, the flimsy exhaust slider hasn't broken off).
That way, the intricate trans is lubricated with the exhaust residue.
Good Luck

If you are familiar with the old Midwest kit of wally Simmers Sniffer then this should be obvious as to the power output of these engines. The original plans showed the Anderson as the power plant. However most have only seen the plans with the moved forward ply motor mount for a Pee Wee 020. Which by the way if you ever leaned it out would overpower the model.
Interesting looking engines but alas they didn't sell really well and soon faded from view like many others when Leroy Cox literally blew them out of the air.
