Finally got to work on my engine to do a little refresh work. I was having the issue in the post below. Weird valvetrain thing. Also, the rings were worn out (bad leak-down)
I ended up going with the parts in this link
Ended up pulling the engine to do the valvetrain upgrade, and hone cylinders with new rings, and new bearings.
I don't normally post like this but I thought it might be fun to share, and maybe motivate/inspire someone else to dig in.
2000 K3500 454/7.4 runs rough; sucks and blows
I have a weird issue with the 454 in my 2000 GMC K3500. I've been racking my brain for a long time. When I watch it idle at the tail pipes it will suck a rag in and out on the right bank, but not the left bank (left seems to run fine). It acts just like what's happening in the video linked...

7.4/454 Cam Upgrade Selection
I need a little help picking a cam. I'm planning on replacing pretty much all of the valvetrain. I have a 2000 K3500 CCLB 7.4/454 with 200k miles and there's and odd misfire that I can only explain by something funky going on in the valvetrain...
