The 340 is the biggest POS V8 Chrysler ever made.
I was grudge racing at Fremont Raceway in my parents new '71 383 auto Road Runner with open rear end (3.23) and factory G60-15 Polyglas GT tires (did low 15's ET). Of course, without sure-grip and punching the throttle at the green light, we had some tire spin.
Then someone walked over to me and suggested I over-inflate the tires for more traction (don't remember, maybe 40 PSI, maybe more). Well, I went to the on-site air hose at the track, but it was only for low-pressure filling of slicks. Drove outside to a gas station, where I pumped the tires up like the guy said. After that, no more wheel spin at take off. Had to bleed the air out before driving home (80 miles one way).
