Wasn't there a Forest green Truppi-Kling L78 convertible? For some reason I was thinking they campaigned both the Blue LS6 and a Green L78.

Yes,this one referenced earlier.
It was a Forest Green Factory L-78,replaced decades later with an LS-6 engine.
Dave painted this car Astro Blue years after he got it in '78.
I have photos of it @ Super Chevy Joliet '99 somewhere,when Dave brought it there.
