Here are the specs.
413 RB around 2000mi on rebuild.
Edelbrock E-Streets w/440 source ductile adjustable rockers
"Purple Cam" .484 lift 284 duration w/ matching hydraulic lifters
0 lash all the way around + 1turn
I did not rebuild the engine myself nor do I consider myself an engine builder, which is why I am here.
I went through 2 revolutions to confirm 0 lash then set all rockers @ 1turn.
Engine ran great and sounded great for about 40-50mi.
Now everyday it has been getting progressively worse (sounding) so I pulled the valve cover, set it at TDC and there is slop everywhere.
What gives? Where did all the slack come from? Adjusters are all still snug.
Is it normal to have to do this procedure again? Just add another half turn all the way around?
Looking for advise as to what to look for or what I might be missing here.
