The classic Dragmaster is more like this, kinda like the Chassis Research K88, but different...
or with double hoops like the Mooneyes frames
Both were available as Revell parts-packs.

The other Revell parts-pack frame was a Kent Fuller version of the TE448, identifiable by its small-diameter-tube X at the rear, with upper and lower forward rails forming a shallow triangle, the basis for the twin-nailhead powered Tommy Ivo car above in Snake's original post.
The TE448 had double Us at the rear, and generally more parallel forward rails, as in Snake's first photo.
And I don't know who built the first one, but I find the Fuller version to be the superior design.
