About time for another update...
Due to a progressive increase in what sounded like a top-end rattle or knock (possibly lifter(s), tensioner(s), or other part, I decided that the original LT5 would run its last mile, just shy of 195K miles. Not the 200K I was hoping to hit, but I really didn't want to push my luck and end up wiping out one or more cams in the process.
Financially, I decided that the best option was a stock replacement LT5. While I'd like to go for a 368 or 372, the cost is prohibitive for me at this time. Also, all of the incidentals are going to be replaced (clutch, pressure plate, flywheel, master/slave), and that of course adds to the overall cost of the project.
The replacement LT5 will be coming from White Racing Products.
Here's where I'm at in the tear-down process:
Headers/Exhaust are off, c-beam and driveshaft off, all electrical connections on motor are disconnected, motor mounts unbolted, cooling system connections disconnected, pretty much all that needs to happen now is to remove the transmission, then pull the motor out.
