Looking For Pics of GM knock sensor on a 360

[ThisGuyUKnow]

Hey guys I have a bunch of projects ongoing. One is getting the holley street dominator that is moded for Tuned port injection installed. I plan on picking up a 1990 350 vette harness from a part out and modding it for my purposes.

ANy how the early TPI harnesses seem to be very close to the GM TBI setups people have been junkyarding so I have been studying some of those write ups for those. Any how i was trying to find some write ups where they used the knock sensor. The bustedjeep one he bypassed the knock sensor(but isnt the knock sensor important for spark controll) I know I have read some where the knock sensor was used in the 360 I just cant find it in search or google. Someone got these booked marked? Thanks in advance.

You should just be able to thread that knock sensor in the side of the block.

thats what I thought I had read before... where exactly though? got a pic?

[The Colonel]

I don't have any pics, but it shouldn't matter where. I'd put it somewhere near the motor mount.

This is where I am getting confused do i drill and tap the block?

[The Colonel]

No, isn't there an extra open bolt hole?

[ThisGuyUKnow]

I dont know I will have to look. Thanks for the help. Hopefully I will get the wiring harness relatively soon and be able to start figuring out what i need

seems to be plenty of google hits on it...

[ThisGuyUKnow]

there are plenty of hits your right but only one of those deals with actually installing the sensor and they say to weld a bung to the side of the block the rest just mention the knock sensor in passing or as a parts list.

THats why i posted here because i know i have seen a thread where it was installed in a preexisting place on the 360. But I didnt realize until colonel replied that the sensor didnt need to go through the case of the engine. I guess that was a dur moment for me

There is a 3/8" (NPT) drain plug on both sides of the block, down low, in the center, remove said plug screw in sensor, done. (The fancy part is finding the right ESC module that likes what the sensor is saying in a AMC 360)
Jeep never used a knock sensor in a 360, they did use one in the 258 at one time, don't know much about that one though.

^^This is where I understood it to go. I am about to do my 3rd conversion, and the other 2 do not have knock sensors on them. They do just fine. And yes, both control timing as well.

[FSJ Guy]

The knock sensor is not REQUIRED for timing control. As its name implies, it only SENSES knock.

You can disable it (remove the trouble code) or bypass it (see Binder Planet's website TBI FAQ for details).

I run timing control without the knock sensor. For tuning, run it up until it knocks and then back off a few degrees. Why back off? Because you can't always HEAR it, but it still may be there.

The sensor allows you to run up the timing as far as you can and then the sensor will let you know when it's too much and will also retard the timing AFTER it detects knock. Useful if you're going to run different grades of gasoline, hence the reason they're put into most vehicles.

I was debating installing one, too/ I am still on the fence, but leaning towards no.

[ThisGuyUKnow]

Well if it can either be threaded into an existing point in the block or still function with a bung welded to the outside of the block then I may as well use it since it is coming with the harness

[blazer3664]

I read on a TBI "how to" somewhere (here??), that it can be installed in a freeze plug. I do not know how it is done though. They started talking about finding the threaded adapters and tapping the block and that was too much for me.

I have read about the welded on bung also, but dont know that I would trust it to stay welded onto the cast block. At least not with ME welding it.

I am on the fence as well, but leaning toward keeping the knock sensor when I do mine.

now the question is if the esc mod for the HEI is the same for the TPI system. I was studying how busted jeep did theirs and it seems like it would be the same system for the TPI setup. I will just have to get a hold of an 90 vette module and see i guess.
