 Well my SBC 350 is making a knocking noise. I believe it is coming from the motor I believe it is coming from the motor but if you put your ear on the fender you can hear like a rattle. but if you put your ear on the fender you can hear like a rattle.  
 
 I tried adjusting the timing and when advancing the knocking would go w/ the RPM's and then it would soon turn into a whistling noise until I retarded it, then it would go back to knocking. until I retarded it, then it would go back to knocking.  
 
 I do not know what this could be be, any help would be appreciated
 
 Thanks
