Cam Swap
Well I'm mostly finished. Just gotta install valve springs on a few more cyls and put her back together. Cam is in.
Timing chain was stretched pretty bad even w only 80K on it. Glad I'm changing that.
My Patriot valve spring kit was missing one of the machined bases so I gotta call them
Has went pretty smooth other than pulling the crank hub, good God that thing is a PITA.
What method are you guys using to reinstall the crank hub?
Got somw pics I'll post later.
Guess I can take my time finishing it. Builder says trans is in ROUGH shape
Got some pics I'll post later of the swap. I'll get some of the trans carnage too.

LT1 timing chains are notoroiusly "loose" explainations are usually "ease of factory assembly" and "reduce load since the cam bearing is already seeing additional load from the waterpump". I am sure whatever you thought was badly stretched was completely normal and no problem whatsoever.
To reinstall the hub I bought a longer bolt, a stack of washers and first heat the hub in boiling water so I can get it good and started before pulling it on the the bolt. I boil it because this way you can get it hot enough to loosen the press fit without making it so hot as to damage the seal. When pulling it on with the bolt make sure to have LOTS of thead engagement at all times.
