41chevy Posted June 7, 2018 Share Posted June 7, 2018 Rod bolts are a notorious weakness on non Hi-Po big blocks. I personally always replace when I get an older 383 or 440. Non H-Po Chrysler went down in rod bolt shank diameter for some reason and than knurled it to fit the bolt hole in the rods.

keg1 Posted June 10, 2018 Share Posted June 10, 2018 (edited) Pulled motor out today. Took pan off, a pushrod, some lifter pieces, other small pieces and about a 3 inch chunk of cam fell out. The block is also vented like the pan. I think a 2 pack of jb weld and I'll be good to go. Edited June 10, 2018 by keg1 Added more Quote Link to comment Share on other sites More sharing options...
j hancock Posted June 11, 2018 Share Posted June 11, 2018 After the JB Weld, you can smooth out the job with a gallon of All Metal.... 1 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...

If you can get to it, keep it in the block so its held straight by the bearings. 1 Quote Link to comment Share on other sites More sharing options...
Freightrain Posted June 11, 2018 Share Posted June 11, 2018 Ohhhh, geez. That's BAD news. Nothing much worse then when the motor gods lets you see the rotating assembly from the OUTSIDE of the engine. My local shop dynoed a motor just a month or so back. Big Hemi motor built by someone else. They fired it up, made some baseline pulls. BAM!!!, rod came out the oil pan. They did a little looking and seems the assembler didn't get around to torquing all the rods? OOOHHH man. All the shop could do is wheel all the broken parts back to the guys pickup truck.

keg1 Posted June 12, 2018 Share Posted June 12, 2018 I never really did much with tearing into engines mainly because I don't know what I'm doing. Not that it matters but is there a way to know what went wrong first, cam broke and then rod broke or other way around? Quote Link to comment Share on other sites More sharing options...

Lay a bet the rod left first and the cam ran after it.Look at the rod bolts for bending or shearing. Mopar cams as a rule do not fail by breaking on their own. I can probably dig out a good short block 440 TNT engine, if I go home to look. Haven't been there since my wife died, should see if it's still o.k. .

Look at the last photo, the rod and wrist pin are still on the crank but not in their original cylinder.

Truck Shop Posted June 15, 2018 Share Posted June 15, 2018 The B/RB blocks and cranks were pretty good but it is a engine that needs a set of Eagle Rods if your going to run one a little hard. At least a set of ARP rod bolts then have the housing bores checked on the rods. Truck Shop Quote One ping only Link to comment Share on other sites More sharing options...
