Many years ago I bought a used engine from a place , they advertised dyno tested etc
The front accessory on the engine was damaged , and the damage was rusted ,
No way was this engine every on a dyno ,
I got the runaround when I called , They kept saying they’d send a new ps pump and water pump etc and never did .
So I called my CC company and did a charge back and wow , suddenly an hour later the place I got the engine from called and was angry , I reminded them we had discussed this repeatedly with no movement , and they overnighted the parts to me and had them on my front porch the next morning to get the cc money released .
