So I am running a hybrid ac system for the ls1 my ac guy didn't put proper oil in the system causing my compressor to seize.

Now my main issue dealt with my fan speed of the hvac. I am using an autozone blower motor and blade. Now the blade is made out of steel. I know that oem is plastic would the metal blade show a decrease of circulation within the system.?

Also Anyone know If the oem blade compatible with this vdo blower motor?
