Hi all,

Came across this site while looking for the RPO codes on a new to me 2013 GMC 2500HD with all of 26K on the odometer. A lot of useful information here. Thanks!

I've been playing with Chevy small blocks since the early 60's (yep, an old fart) and never seem to get tired of building them. Current build is an all aluminum (Dart/AFR/Callies/Oliver/JE), old school 441 inch small block to replace a 381 inch version of the same currently in my 55 Willys flat fender Jeep.
