Oil Support Rails and Drag Racing

@hemi446 Do the chevy pistons have the cut out for the pin to go through? or do they run the support rails with pistons that are solid just to do it? Wasn't sure what you meant by your statement.

What's better to run with a button or the support rail having a dimple in it. Both eagle and scat kits that are offered do not have the button only the dimple support rail. I find it hard to believe that little dimple will keep it from spinning.

Thanks
