I started my 440/543 the other day. 10-1 compression, victor heads long duration solid roller cam. I heard lots of valve train noise. So I adjusted my valves, it helped. My distributor is locked out at 34*, I have some slap/ clank noise. Consistent with rpms and goes away above 3000 Rpms. Is this detonation? If so is it because I have locked my timing at 34 at idle?
Sure it isnt valve train

It sounds somwhat like piston slap, but I was wondering what the locked out timing at idle would do? It is a very distinctive sound, not a light clackity clack.
How many miles on it... piston slap/skirt slap usually gets quieter when it warms up.... you could have a broke skirt(just guessing) start with the easy stuff like the rockers

It does seem to get a bit quieter when warm, well the pan is coming off since it leaks a bit. Guess I may as well check rods and everything else that I can when I'm in there. Alaowhat do u guys seal ur pans with? Cork? Sealer?
I just use a good RTV with no gasket... put a bead all the way around get the pan in place with all the bolts and pull it up so there is about .050 left to tighten and let it dry over night... tighten it the next day after it drys
