Hello, i had my engine totaly rebuilded, new pistons, chain, crankshaft, bearings etc...
After we did all that, we heard some ''hit'' at the top of the engine when u rev it to 3-4k rpm. Missfire is here as well.

we measured camshaft, but my thoughts are that engine, i mean crankshaft and camshaft are not fit correctly.

Anyone had that kind of a problem while rebuilding?_

Every information is appreciated.
