Some us might be curious where connecting rods fracture when they "give up the ghost". Can anyone share some fotos of such failures? Thank you.
Sucks your motor blew but the way that rod got twisted is awesome!let's see bought a set of stock "reworked rods"...balanced...beams polished..new arp rod bolts...shot peened....broke after the 5th run...shifting at 6200 rpm....using with a kb107 pistons...
broke a set of stock rods ..shifting at 6500...swinging a heavy dome TRW pistons...at 7000 rpm thru the traps went it broke
broke a set of stock rods back in the mid eighty...pretty much destroyed everything in the block...

I must be one lucky SOB because I've never blown an engine either.....even after spooling a 44O to 7300 for over 300 passes! Most of my cars have been airborne several times and have spun them out on the beach doing 60+ with the throttle matted.....doing neutral drops were common along with going from drive to reverse floored at 40 mph and going back into drive. Did this kind of crazy crap for many years. The list is long! Some of my friends refused to ride with me even after telling them I would act normal lol

Oh man, that's funny! A buddy of mine had his mom's station wagon and was 'demon-strating' his skills to several of us that were standing around watching. IIRC, it was a mid 60's big Plymouth and he was going to manual shift the automatic and I guess he got a rambunctious with the shifter and stuck it into reverse. The car nosed over and saw the rear end bounce up off the ground lol. It killed the engine pretty fast but he probably let off the throttle too thinking something was wrong (you think?) and then he had a hard time getting it started back up. We were laughing pretty good about then....That's crazy you said that, Back in the late 70's I had a 70 340 cuda with a slap stick shifter round knob with button on top. I was getting on the xway full throttle low gear and hit the lever apparently hitting the button and put it right in reverse at full throttle at 6000 rpm. The 340 never slowed down just started smoking the tires in reverse and the car got sucked down to the ground and I smashed my face into the steering wheel (no seat belt) so I couldn't get my foot off the gas so I just pulled the lever back and the car about jumped off the ground and off I went down the xway like nothing ever happened, never hurt a thing except my nose.
reworked rods should be magnafluxed. my 340 has reworked 3418645 rods going to 7000 since 1995let's see bought a set of stock "reworked rods"...balanced...beams polished..new arp rod bolts...shot peened....broke after the 5th run...shifting at 6200 rpm....using with a kb107 pistons...

reworked rods should be magnafluxed to check for cracks

Magnafluxed rods is not a guarantee, just makes you feel better until the rod or crank lets go.reworked rods should be magnafluxed. my 340 has reworked 3418645 rods going to 7000 since 1995
Mopar must have chosen Eagle as their crank producer back then!How about a broke cast crank. 318 out of a 75 valiant. Not sure what happened, it died on the guy and he gave me the car. All the bearings were fine, no sign of any other failure inside the engine.
