Aftermarket connecting rods

[TjMiller]

How come aftermarket rods for the 6.4 are so expensive? Low production?

 

[swinky]

They all are expensive

looks like 7.3 and chevy 6.6 rods are around $2500. They are expensive also. Maybe the 6.4 are twice as strong?

the offset cap adds to the cost, that is why they are more.

I wondered that. At what point do they become a necessary upgrade?

900 hp is what's claimed

6.4 is a stout motor and are holding well over 1000 hp without bottom end work

None of them do it for long at that power.

Seen plenty of 5-600 hp trucks with bent rods too. Fwiw

We will see how long my used rods last. 12k since I've had them in

Tuning will play a big part on longevity. no matter what power levels are at

You didn't put in billet rods?

 

[Mike@MPD]

Nope. Those things cost too much lol

Does running a single and the power being up on the top end matter for this conversation? Mike's truck makes huge power but way up I'm the RPMs right?

My guess is that at 1000hp it all matters

For low end torque I would guess it helps if it comes in later and good tuning will always play a role

I can vouch for that I bent #1 rod in my engine I was running around 550hp

That's definitely my concern, as far as low end torque. Comparing charts makes me worry even more about my stock rods, making over 800ftlbs at 2.25k rpm. You're chart not being over such a long timeline because it starts higher in the rpm range does no justice at how quick your power comes on over 2.75k rpm, it's got to feel unreal.
