sorry guys, this may be a stupid question. I'm swapping motors in my car (305 to 350), where is the tpi sensor located and the knock sensor? The lo3 is already out of the car and i pulled a punch of sensors, but i don't know what they are?

 

They have an entire board on swapping motors...

Flowmaster 80 series muffler, K&N Open Element cleaner, Subframe Connectors + a lead pedal foot

 

the knock sensor is on the rear lower pass. side of the block just above the oil pan. The TPS sensor is on the pass. side of the TB directly across from the throttle cable/TV kickdown/cruise control cable connections.

thanks for replying. Do you happen to know what kind of knock sensor I would need for a 350. Is it all the same?

 

the 91-92 knock sensor2 are the ones to get.they aren't as sensitive as the earlier sensors

I also belive that the TPS is differnt for a TPI, assuming that you are switching the TBI for the TPI. As far as the knock sensor goes you will also need a new one for the 350 but I would go with what ever year injection setup you are using. (i.e. 91 Speed density TPI, 88 TBI, 88 MAF TPI, etc). The ECM is whats going to interpret the data from the sensor and thats what it was designed to work with.

 

thanks guys, i am going with a holley tbi. I have another question,? theres are two sensors by the exhaust manifolds on each side of the motor, what are they?

 

well you have on the pasenger side, the knock sencer, fan temp sencer...on the drivers side you have oil sending unit, temp gage and on your exaust you have your o2 sencer hope this will help you.
