Yes pretty much all of them, 301 Ponchos, just had one in the shop about 3yrs. back. Indy Pace Car edition TA, still ran. The old 2.3 turbo Mustangs, same era, Colts.......We had an '83 T-Riviera, ended up changing the turbo, ran fine. Smokey Yunick's "Hot Air Engine" used a draw-thru "Homogenizer", but required synthetic oil to live.
