blower motor specs

[kglowacky]

does anyone make a high-performance blower motor for my 78 c-10? I would like a little more airflow coming out of the s/c vents.

I replaced my blower motor with one out of a 91 and it puts out some good air.

As said should work.
But you have A/c system then you will not get much improvement, But None A/c system you can buy a A/c motor ( but you want the motor to have a threaded end with a nut or a flat spring nut clip so you can take off the A/c long cage and put on a new None A/c cage ( or your old short cage ) The motor should have steel magnets around the motor housing that the higher output motors.) " Do not buy the cheap molded cage to the shaft of the motor" Because the A/c motor will not fit the none A/c housing.
