To dyno my rebuilt engine? On Monday I am having it sent in so they can get it running correctly. The following Monday they are having a dyno day, $60 for 3 pulls.
As long as it is properly built, the rings are seated and things like oil pressure and operating temps check out, you should be good to go. Make sure the valves are adjusted properly and all bolts like intake, exhaust are checked and retorqued after the first few heat cycles.
