If chasing his old address and phone, he moved a couple years ago.  I also see him on FB

Yes he did, he’s in Chiloquin Oregon now I believe.

I don't have an old parts and time guide that would be accurate, but I'd say, most guys are going to run from that job.

Cam change in the car, cleaning surfaces, degree, rocker patterns, valve clearance, pushrod measuring, header bolts, intake fitting, all done pretty easily on the stand but not nearly as much fun in the car  Not to mention dropping the pan or using the little repair gasket that comes with the timing set is just a little goofy for a real nice build.

If no issues, a day job plus parts with the engine on the stand, if paying to pull the engine, I'd say 4-6 hrs to pull, 8 hrs to prep, clean and assemble (plus chasing parts) and an 8 hr day to get it in and running.  Likely parts to chase in the middle mean it would be a week or so job.

If you listen you can hear the clunking.

He has an active facebook page he posts on

 That’s what happens, it goes up the driveshaft and comes out the trans like a screwdriver to your ear. Still didn’t hear the noise but interested in what you find.
