so it might take a little more work than I wanted
I am thinking I need to cut off the motor mount perches and lower the motor for better header clearance.
the blazers had the perches that raised the motor to give a better drive shaft angle due to the shorter wheel base than the trucks.
I am going to lower the rear 3'' so I don't think taking the perches out will hurt me. I think it may actually help me.
and I think I need to change the throttle cable and tv cable but not sure on that need to test fit the 4.3 ones
