That's consistent and that's a good indicator that the engine is in decent shape. A little low. Do you know if the camshaft was degreed or was it installed dot to dot? If dot to dot, it might be worth your time to degree it. If you don't want to go to the trouble, then we can move onto getting the ignition timing optimized. I would recommend looking at the camshaft timing though, because getting camshaft and ignition timing both where they need to be can add a lot. Up to you though.
