I have to get new rods. Have 1737692's but 2 of them have DF81 on them and the rest have DF157 and have more metal. I looked them up but the DF numbers did not come up at all . any info would be great. And if anyone knows of a place to buy some rods that are not $400 that would be great.

1970 Challenger R/T 383 B

 

I have some 440 Six pack rods for cheap. All I would have to do is press the pins out of them to remove the pistons.

 

I would just buy the $400 dollar new rods because by the time you buy other rods put on new rod bolts, and have them machined and reconditioned, your just about there anyway.

 

wouldn't the 440 rods be longer . I found a set on eBay for $47 that fit a 440 if thous would work I'd get them . their new with ARP bots. thanks for the offer thought.

 

New rods with arp bolts for $47 ? I wouldn't trust that. If your wanting to replace rods for a B engine then I would get b engine rods. you could possibly use RB rods if you can find a piston that will work for stock stroke although I'm thinking the connecting rod journals on a RB are larger than on a B engine.

 

Ooops just checked the con rod journals are the same size.

 

Yes i was reading that you can use 440 rods with a smaller compression hight 383 pistion and 383 crank. I think it was $47 each.
