The camshaft on this small-block '73 Corvette required removal of the radiator. Although the A/C condenser did not have to be removed, the left lower corner had to be lifted up over the headlight actuator to provide sufficient clearance. This may not be necessary on all models. Measure to see if there's 211/2 inches of clearance from the front of the block at the cam centerline. Remember, the fuel pump has to be removed because of its cam-operated pushrod.
