Thanks for posting a pic of that Jadestone green 61 Jerry. That is what mine will look like as it is that color.
Here are some from my stash, do not think these have been posted yet.
Infinity 4 while it still was running Pontiac power.
Another pic of one of the Thompson Dragmasters. This one has the 'mystery' heads that look like 1971 455HO (even though it is about 1962).
Here is an injected Poncho digger with custom injectors on the rollers (running quite fat I might add), that I have not seen before. Looks like from the mid 70s to mid 80s to me.
This is, reportedly, Infinity 5 after Don Gay sold it to Bob Riggle. can anyone confirm?
Another pic of the Eddie Hill twin known as the double dragon in '64 with his purple GTO in the background. Note full body and long wheelbase as it evolved into.
And here is another identified slingshot with Pontiac power. My guess is around 1960.
