Dio Tipo track/street toy build.
Wanting to build a Dio Tipo for resell faster and less expensively than will happen for a pure street car.
Seems a decent track car sells for as much or more than a street car without the registration hassles.
May just build it for Track/Hill-Climb and let the buyer make it street legal if desired.

The big question becomes, who's rules do I build to?
Lots of "Vintage Racing" and "Track Day" organizations around the country now.
Building to current SCCA Sports Racer rules means an ugly full cage that might hinder enthusiasm for the vintage body style build.
Vintage racing is generally a bit more tolerant of fewer bars.
Do I concentrate on NV/AZ/CA/OR clubs or is there a national club other than SCCA?

I have a nice strait TR6 chassis and a TR6 engine that was built for some sort of road racing with zero miles on it.
Been sitting so I've torn it down for a refresh.
Old assembly lube had petrified so it did not spin over.
Some very nice pieces included in the build, ported head, Arias flat-top .040" over pistons, trick aluminum dual-disc flywheel setup, polished beam stock rods, new 25225 cam ("125 HP"), new lifters, etc.
Going to get to play with that burette I have hoarded all these years in order to CC the head for compression calculation.
Hoping I can use the Weber intake I bought, not sure with the enlarged ports as the intake is thin where it joins the head.
Pretty sure this engine will make significantly more than the stock 100 HP even with Stromberg's.
The light pistons and flywheel should let it rev quick too.

Making progress on sorting out the engine.
found basic specs and volume for the head chambers at 38cc.
So 11-1 compression.
Stock US spec engine made 100 HP, kind of low.
This should be good for about 150 HP which is fine for such a light car.
Looking into setting it back about 6" for better weight balance.
