Hey guys i have this knockin sound coming from the engine bay on start up but at idle it goes away, until you rev it to 2k rpms then it makes a squealing noise. If anybody know what it is or might know please let me know. Thanks

 

Sounds like you've got a spun rod/main bearing or three. Good time to get that fancy new strocker kit now. Get a hv/hp oil pump no matter how you decide to rebuild. You can search spun bearing in this forum and find all kinds of info. Good luck

 

that sucks man, holler at me if you need help with the mechanical stuff....
