SB engine rebuilding got ya! School is Open!

When you install the oil pump you fill with oil and turn it and all looks peachy. When you install the oil pump on your engine and torqued down make sure you drop a priming shaft in and it spins free. I installed a bad pump which would turn freely in your hand but when torgued down in engine would bind up. I found this problem when ready to fire engine and had to drop the pan in the car with headers installed. I won't make this misstake again.
