As some may have know, on July 29th my GMC had to be towed home because a busted #6 exhaust valve broke off and took out the piston.


fast forward to this past weekend, I spent friday-monday installing the rebuilt transmission, new radiator, tranny cooler, and all the other work that goes into installing a rebuilt engine. My friend came over Monday, we primed it up, fired it up, and ran in the cam for 20 minutes. All went well, the engine sounds good and seem to be running well. Last night I re-torqued and checked everything over, bolted my driver seat back in, and took it for a drive and all seems well. 37 days it was parked in the driveway.

Anyway, I have followed the engine re-builders recommendations to a T up to this point. This is pretty much where the instructions ended and opinions on what to do next started. only thing left on the checklist from the Rebuilder has to change the break in oil at 500 miles.

So I am putting up for discussion, and I am sure I will get many suggestions as I already have, as to how one would drive this coach with the new engine for a while, but what I would really like to know is what NOT to do. I know I will be sitting out the radar run this Saturday. I need to drive it to the RV dump, and then off about 75 miles East this weekend. another trip next weekend an hour north. So I should have some pretty decent road trips to get the next 500 some miles on the coach.
