Theres a guy in MI goes by 'HillBilly' racing one of those. Serious business. Had a buddy had a '76 that got upgraded to a 302 with the goods. The Grabber was an example of such a thing.
'Nother dude has one with a dual quad tunnel ram, local yocal. Pretty nice and STOUT.
Oh too, that Maverick thing, it's as wore out as Amy Winehouse.
