1900 miles on motor and got a loud rattle

[madvette74]

I noticed a slight rattle about 150 miles ago very subtle, I in no way drive the car hard.. I can rev the motor in neutral no rattle.. but when there is a load on the motor it will, so if I am driving by another car I can hear my car echo of it.. if I accelerate 25 to 50 percent I can her it clear and loud.. pretty dam loud, and my exhaust is loud.. now it gets louder the hotter the motor, but still wont make the the noise idling or 3000 rpm revs in neutral... I pulled the valve covers and intake, rotated the engine checking for loose rockers or a bent push rod, something that could tell me its in the valve train area... now the car is a 4 speed, 383 stroker, hydraulic roller cam and crane roller rockers... I dont want to risk engine damage or to my AFR heads.. has anyone come across this problem and or know what it could be?? Added a pic of drivers side.. Thst side sounds normal to me . the passenger side sounded louder.. That was the first side I wanted to check..

Here is the passenger side. After looking at it. It looks like most valves are closed, these pics are about 5 degrees after tdc
