Are 305 and 350 intake manifold the same?

Looking for an answer to the question: Are 305 and 350 intake manifold the same? On this page, we have gathered for you the most accurate and comprehensive information that will fully answer the question: Are 305 and 350 intake manifold the same?

The knock sensor physically looks the same between the 305 and 350 version, but they do are not the same. This is very important, and should not be overlooked. The knock sensor is responsible for detecting detonation. Detonation produces a specific frequency that travels through the engine block.


These are the only things you will need to change or worry about to properly convert to a 350: The size of the injectors was a very important difference between 305 and 350 applications. ALL 305 TPI engines came from the factory with 19 lb injectors. ALL 350 TPI engines came from the factory with 22 lb injectors.


The 90-92 350 TPI F-Body engines (Camaro and Firebird) used the 1227730 ECM, and so did the 90-92 305 TPI engines. The 1985 305 TPI engines used 1226870 ECM, which is the same as the 1985 350 TPI ECM (350 was only available on the Corvette in 1985).


First of all, the TPI intakes (manifold, plenum, fuel rails, throttle body, runners) were exactly the same between 305 and 350 engines of the same year.

profox02, I owe you an apology. Your 305 heads will fit on the 350 block; however, you need to check what you resulting compression ratio will be. This is because the 305 heads have a smaller combustion chamber than the 350 heads. The result could be that your engine will require very high octane gas.
