Any thoughts / feedback on the 440 Source "I" beam rods? (for hot street/strip builds as an alternative to rebuilding stock rods)

How is Size, consistency, quality, success or problems etc...

They list them as 5140 alloy with arp 7/16" rod bolts. Seems like similar specs to an eagle SIR rod, but eagle doesn't list that app.

I wish SCAT made an I beam for these engines as I've had great experience with the Scat 4340 I beam rod in other applications.

Thanks!

they're great! you can break them as good as any other rod,

I have been using them for 3-4 years no problems

Why "I-beam" and not "H-beam" ?

I have had them in my motor for 2 years with no problems either! Their stroker kit 383/496 and spray 200 shot...Matt

Maxeffort,

The rod you are showing is more geared toward a stock high performance application. Make sure you are looking at the correct rod for your application. If you are choosing between these 5140 I beams and some 4340 H beams the h beams are stronger!

The last time I called(several months ago) 440 source was not selling thier I beams rods anymore, at least the 7.1 long BB Chevy type rods BTW, I do have a set of them in a street hemi motor, two years on it now

440source rods in one my Hemis..No problems yet
I wanted to get another set(spare) but they aren't made anymore.

They're still on the website, at least in the 6.76 size. I'll have to call and see if they are avail.

First set I got was way out of round on the big big..sent them back..They didn't have anymore then..I got the H-beams and they was fixable.

we have been running those rods since 05 No problems.3400lb car 10.0s turning 7000rpm.

We had a set in a 64 Plymouth which was a 11.70 street/strip car. Our machinist liked them better than the CAT rods he had for another build and it was cheaper to buy them than rebuild the old rods, plus they came with 7/16" bolts. They did have alot of side clearance, but that didn't seem to be a problem with excessive oil on the cylinder walls. OK for a budget build it you check them.

I'm running the 440 source I-beam rods but there not the one's you showed. Those pictured are stock replacement rods not for a engine that will make any power.

Not knocking 440 Source or any of the lower end products, but constantly hearing they need work to run, what does a set actually end up costing...?????

I've been running them for over 3 years now. Same short block with different head made 850hp and ran 9.40 at 144mph. Wanted to slow the car down and went with some unported -1 and I've been running 9.90s for the past 2 years.

Mine were dead on, no work needed. I've got close to 700passes on them so far.

I've never had any problems with any of there part and I've built 4 motors with their stuff so far.
