Default Knock sensor questions

I have heard that a LT4 knock sensor is not as sensitive as an LT1. Is this true? Would an LT4 knock sensor fit in a LT1? I have a LT4 topend package.

It's not that it is less sensitive, it's just smarter about detecting false knocks.

It's a plug-in replacement. You probably need it with the LT4 roller rockers.

LT4 knock sensors will not work on the LT1. However, you are probably looking for the LT4 knock module, it will work on the LT1.

The actual knock sensor is the same in the LT1 and LT4. As stated above, only the plug in module is different.
