"One test is worth a thousand expert opinions."
I had a friend with a video camera come by today and we did the 334 ver. 3.0 break-in.
So far.......... SUCCESS. The pushrods rotated and all of the rockers had a more than adequate
supply of oil. No strange noises either. I ran it at between 2500 and 3000 rpm for 20
minutes and then kept backing it down in steps towards idle for the next 20 minutes. Then
I played with it for another 5 minutes.
Tomorrow, I think I will remove the valve covers and inspect the magnets in the heads for any
signs of abnormal wear and then run it again to heat the oil up, and then drain and strain it and
inspect the magnetic drain plug. I did check the dipstick and the oil looks good.
At ~850 rpm idle, 16" vacuum, 38# oil pressure (hot), 12 deg BTDC initial, and 32 deg at 3000 rpm.
Next is to do the tip conditioning to the ends of the running valve springs. The camshaft was broken
in with stock (lower pressure) springs to give it the best chance for survival. I also left the valve seals
out for break-in. After I swap the springs, I can change the rev limiter pill in the MSD to something like
6400 and see what the engine is really like. The rpms are limited to 3400 rpm while using the break-in
springs.
You were right Brian - ISKY lifters are good.
Rick, the videos are being transferred to a thumb drive. How do you want me to send them to you for
your excellent editing skills?
