Aftermarket connecting rods: your .02 ?
Im gonna build a 455 for my T/A which will be a corner carver as Ill also be modifying the suspension for the twisty back roads.
What aftermarket connecting rods are good these days ? Is a stock windage tray sufficient or should I look into oiling mods ?

I currently have Eagle rods in my 474. If using Eagles I would do the bolt upgrade. For my 535 build in progress I am considering Callies rods.
As for the stock. Windage tray has a tenancy to develop cracks and fall apart. |

Cliff has posted that most all the Chinese H-beams he's seen have checked out good. The RPM H-beams are usually about $65-$75 cheaper than Eagle Pontiac length rods.

Callies alas uses L19 rod bolts which are stronger under ideal conditions but potentially way weaker owing to susceptibility to moisture. A rep at Callies would inform me in a 2018 phone call that Callies uses the L19 bolts for the past few years, even though many internet vendor listings for Callies will continue to state that they still use ARP2000 bolts.

I have SCAT in one motor Eagle in another motor.
Canton has better baffling than the Moroso for cornering. If you have an auto tranny and really sticky tires you might need to extend the vent tube. My TA used to sloch tranny fluid out until I did "fogging mosquitoes" when it hit the exhaust.

I used Eagle rods in my current engine build. They are very nice rods. Machine work was excellent. Sleeves in the threaded holes on the journal end to locate the cap. Done very nice. Screwing down the ARP bolts felt like turning a micrometer....the machined threads felt like precision work.
I didnt upgrade the ARP bolts since I am sticking with stock power levels. For me, this is the first time using forged rods in a Pontiac engine so I can only compare this set to the prepared cast rods that I used to use in the 80s and early 90s. Back then I couldn't afford forged rods. Glad to see there are so many reasonable choices available these days. Sounds like a fun build. Sent from my SM-G930V using Tapatalk |

If your corner carver will have a need to do sustaned rpms above 4000 and your 455 is still based on a 3.250" main Crank then a oil cooler and aroad race type baffled oil pan better be on your list of needed things because it does not matter how good your Rods or your main caps are when the Bearings go south first due to overheated oil and or oil starvation!

My RAIV motor does have Crower billets but when I built it there were few choices. I want to think they were kind of heavy also 900gm range.
