1970 Datsun 510 2.2L

Hi Nick, Houston, we have lift off!!! Turned on the unit for the first time with a fill-up in Florence. Basically lacking the needed courage, I filled up with Plus (one step back from the Super I'd been running) and headed south down 101. At Winchester Bay there is a long hill south of town and as I started to climb I thought I'd do a "ping check" so, under load in 5th I stepped down and, not only did the ol' gal not rattle herself to death, it accelerated. Not neck breaking but picking up speed. Never would have done any better than hold steady speed before.This is exactly the seat of the pants kind of stuff I'm looking to document with a fairly tired motor (130k+). Thanks,
