* Lifter Differences: The 305 sometimes uses hydraulic roller lifters that are different than those in a 350. A cam designed for a particular lifter type won't work correctly with the wrong lifter.
* Lobe Separation Angle (LSA): The LSA can vary between 350 and 305 cams, affecting performance and potentially causing valve-to-piston interference if not carefully matched.
* Cam Shaft Diameter: While usually the same, there might be slight variations that could prevent a 350 cam from fitting properly into the 305 block.
* Specific Cam Profile: The overall profile of the camshaft (duration, lift, etc.) will determine how well it works with the 305's smaller displacement and different characteristics. A cam aggressively designed for a 350 might not be ideal for a 305.
In short: You need to carefully compare the specifications of the 350 camshaft with the specifications required by the 305 engine. Simply assuming it will fit is risky and could lead to engine damage. Consult a reputable parts supplier or engine mechanic before attempting the installation.
