Hmmm, from 1981 huh? If this is the car I'm thinking of this looks like the street machine nationals in Sac and I believe Roland Merman owned the car then. Or I saw him driving it at the event anyway.
Nope, same car, but Robert "Tach" Mooney owned it in 1981 and the show was at the Fariplex in Pomona. Roland bought it around 1984. I just found long lost video I took of it with Roland at the wheel from the Tognotti's show in Sac in 1985.
Tach was the original builder of the car. He sold it to Roland minus the blown hemi and Roland put a tunnel rammed hemi in it (video will be up on YouTube within a couple of days, but the quality has really degraded as it was copied from the original Beta tape to VHS in 1986).
