However, several modifications could potentially lead to this catastrophic failure:
* Excessive rod length: Using aftermarket connecting rods that are too long will reduce the clearance.
* Incorrect camshaft installation: Improperly installed camshaft (too high or too low) could reduce the clearance.
* Crankshaft journal wear: Excessive wear on the crankshaft journals can change the position of the rods.
* Block modifications: Significant machining to the block could alter the dimensions and positioning of critical components.
* Extreme piston-to-valve clearance issues: While not directly hitting the cam, severely close piston-to-valve clearance with aggressive camshafts *could* potentially damage the connecting rods indirectly in a severe case of valve float or piston-to-valve collision.
If you're considering any modifications to your 350 Chevy, always consult a reputable engine builder or use verified specifications and procedures to ensure correct clearances are maintained. Connecting rod to camshaft contact would indicate a serious and potentially expensive engine failure.
