Hey ya'll built a 383 stroker and everything seems fine. I have about 6k on it and it runs strong. It has had a tap thought since new that is bugging me. At about 2000 rpms it is loud enough to hear in the drivers compartment. I've adjusted the valves with no change. It is not a rod or main bearing knock, could be valve train but I'm not sure. Being that it's a stroker I did have a crank windage tray contact problem early on but I fixed that "I think" any ideas or simular experiences?
Just a thought, what kind of clearances did you have between your rods and block. Disconect one wire at a time and see if the noise quiets down. How about piston slap. I would do the lifter ajustment thing first. one at a time. It you put your finger on the rocker arm you might be able to feel it.
