Upon initial startup, take it up to 3000 rpm and hold it there for 30 minutes, keeping an eye on temp and oil pressure. That's the best way to break-in a new cam. The rest of the parts in the engine do not respond as much to break-in.
So your suggesting running the engine at 3000rpm with no load. No wonder your TA has no compression in 2 and 4.
OP
The wheel isn't being reinvented here. I've rebuilt 3 of my own engines as well as 4 with friends,not including the cam swap in my 99 chev z71.
I also installed the big bore kit on my Harley,with a drunk experienced friend there overseeing the whole operation.
In every case I took the vehicle/bike onto the highway and ran 2nd and 3rd gear pulls. Going 3/4 throttle thru both gears then down shifting to load the rings do I was loading both ways,with acceleration and deceleration.
I ran from my place in the city to my girls place(30 miles)then changed the oil and filter. Drove normally after that.
Nothing is consuming any oil yet,and in the Harley I'm running thinner than spec oil,the cars and truck are running spec oil with no consumption either.
Sounds like you've got a great engine there. What is it in,or what are you putting it in.
