ok, I got six pack rods with casting # 1851535 which according to http://www.mek1.se/chopper/dart/tech/rods.htm should fit the 426, so will the same rods fit the 426 hemi? I read elsewhere that they were not standard in the 426 hemi. Well, I also have a set of rods that I was told were six pack rods but the numbers don't match up. On one side, it has DF14 MS3049 and I think the other sides has 2951908 so what I want to know is if they are six pack rods and if they will fit the 426 hemi
someone please let me know, thanks

I wish I could sware to this, but it's been a long time....

The 1851535 rod's are short deck (426) rods with a length of 6.358
The 2951908 rod's are beefed six pack rods. The length is 6.768 and used in RB raised deck applications.

 

The six pack rods fit 440 cid only. They were used in all 440s after 1972 because they were beefier. Today we go for lighter and stronger But most puriest still go for the six pack rods when building a 440. I have a 1976 440 and plan a rebuild in the future, I will see for a fact if the 440 six pack rod theory is true

 

so when you say the 1851535 will fit 426, you mean the hemi right? what does the short deck mean? I'm not sure if there is a difference. On the 1851535 rods where factory pistons with casting #s can someone tell me what they are? 3671217 12 09104 3671218, according to http://www.jccpiston.com/manufacturer/16775/16775.html it looks like it was from a 440 V8 1972-78 (J218)
can someone confirm or deny this? I'm building a hemi engine with the newer mopar block with Indy heads and other parts, need pistions and want to know if these will fit, please help

 

I have not worked on any Hemi engines and I'm not too familiar with the part #s. B and RB are the abb. for B block and raised B block. B=440 and RB= 383 and 400. When the blocks are bare the 440 will have a tab and 383 and 400 will go straight across the front where the front intake bar bolts down. I hope someone can chime in who has expierence with the Hemi engine and knows where to find the #s you need.
