Probably a dumb question , but how do you post the screen shots of the data dash on here ?
I have a unreal knock count problem I am fighting with my S10 ('7427) and I thought a screen shot might be helpful.
Thanks

But, for something like that, it might be more useful to post a datalog.

On my laptop, there was no built in screen shot feature. I had to download a program to do it. Its called screen hunther, and works pretty good, and it was free.

At least it's consistent false knock counts?
IIRC from another thread there are basically three knock sensors based on frequency of the bore of the engine. So 4.3, 5.7 and 7.4 I don't remember where 5.0 fell in there. So with a 401 maybe try a 454 knock sensor? Or your not supposed to use Teflon tape because it dampens the sensitivity, so use Teflon tape! Another trick is use an brass elbow to reduce sensitivity.
There is also a small torque setting for knock sensors. If you over tighten them they squeeze in becoming more sensitive.
Motor mounts worn and metal hitting metal, headers or exhaust hitting, any rattling. One guy on thirdgen camaro got knock from a rear control arm bushing worn out making noise under load!

Not neccesserly if you do the things I mentioned above you could get it to work, at least be close. Some motors just make to much noise like solid lifter cams, gear drive cams, old noisy motors...
Cool!
But anyone can get a BB to fit without the front clip...
Sorry had too...
What did you do for motor mounts? If you used leaf spring bushings I have had trouble with them and knock counts... look at the tips above, I have got a bunch to work that way.
If you can't get your knock sensor to work on a conversion get the factory spark advance curve and use it. Go the old fashion way uphill load and listen for ping. Hot summer day will be worst case senario...

I had copied the info in the Knock Sensor Topic of Week thread but GM info was Knock sensor was based on bore diameter, which I guess put off differant frequinces of knock noise? But they had three listed. Your right in the middle and 5.7L is obviuosly not working so mybe the 7.4L knock sensor with your same knock memcal and test.
Again we need to find tourqe specs because overtighening causes them to be more sensitive, I'm guessing because it's a tappered thread and tighter squezes them. Teflon tape about 3 -4 wraps makes them less sensitive. Brass elbow makes them less sensitive. Could be trial and error and documenting for others to follow and add too!

Mabey we need to start a knock sensors and false knock thread so we dont highjack the OP's thread.
