Looks like a cool project. So the 5.3 has been in and running and then back out or what?

WOW your current DD was CHERRY when you bought it. Id seriously love to find a truck like that. One that has never been fucked with. I love my truck but it has been to hell and back before I bought it and then again after I bought it. I need to find some old grampa with rcsb obs he bought brand new and never messed with and is in good condition. That way I could start with a clean slate.
Anyway, back to your project. If you need some help and Im off I could swing by and give ya a hand. Ive got a real soft spot for OBSs and I like to see them come back to life.
