More thoughts on the Thunderslot series:
The “white kit” comes with enough parts to build several versions of the Lola T70 Spyder:
There are two windshields, two dashboards, two driver heads, four roll bars and three engine options. There is a Chevy engine with vertical intakes, a cross-ram block as run by Donahue/Penske, and a Ford Indy dual overhead cam engine with bundle-of-snakes exhaust over the rear deck. Note that the engine supplied with the Gurney #30 car is incorrect as it has Chevrolet valve covers rather than the Gurney-Weslake heads on a small block Ford engine. Right now I am thinking that I am going to race a Spyder, set up as the #21 car with the Ford dual overhead cam engine as raced by Parnelli Jones and Mario Andretti. Presumably, this car, as well as others, will as some point be available from Thunderslot.
In comparing the coupes and spyders, my red coupe weighs 63.1 grams and the #30 Gurney spyder weighs 58.5 grams. The front/rear weight distribution between the two cars is within one percentage point. It remains to be seen how the two cars compare on the track. The spyder is a good bit lighter but the coupe may have a slightly higher center of gravity which may help weight transfer to the outside wheel for more cornering grip.
