Pro Stock. The good old days

I know, right? Who in their right mind wouldda ever thought a big block wouldda fit in one? I don't remember what Glidden ran, I think it was a small block, but there were several who ran big motors in them.
Yeah.. one comes up for sale now and then all setup for racing.. they are soo tiny..

"so it was shocking that he came to the 1979 Winternationals with a Plymouth Arrow powered by a smallblock
Mopar engine. Most trackside observers predicted it would take Glidden at least six months to sort out the new combination, but Glidden secretly had been
working on the project during the last half of 1978 and was in midseason form in Pomona, where he not only won the event but tied the national record with a low
.t. of the meet 8.49 and set top speed at 159.57 mph. Said Glidden, “We’d had a lot of success on the track with our Ford
program in 1978, but I wasn’t getting any financial support from [Ford]. Plymouth approached me during the middle of the year and offered some
money if I would switch to one of their cars.”
