'89 R3500 Crew Cab 2wd to 4wd conversion & beyond
- Thread starter mrk5
- Start date
Started out with 2wd TBI350 with SM465 to current 4wd with 454, 700r4, NP241
Looks like fun. I need to get set up for snow wheeling and find some wheeling buddies up here. There's plenty of the white stuff not too far away.
So mounting the knock sensor is tricky in the 454 with the dipstick.
Driver side would be more difficult because the same cool drain plug is somewhat under the motor mount bracket and there's not even enough room for an elbow.

Had to use an NPT extension to make it work. Tried an elbow first but it wouldn't fit with the dipstick. Not super thrilled about it sticking out so far but it is what it is.
Not sure that that is going to work, may not hear any knocking.
Did quite a bit of reading and there is no definitive answer, just a lot of conjecture.

I could maybe put it here:
It's a "blind" hole. Don't know if it would connect to the water jacket if I drilled it out; not sure I want to be drilling holes into a perfectly good block. It could be drilled and tapped to fit the sensor. It's a similar location to newer 454 picture I found.

Kinda wonder what that threaded boss is even for. Clutch linkage?
Think I should leave the hole blind?
You rang?
Where should I mount the knock sensor?
the hole you have it in now, mine has a NPT plug in it.
Why not move it to the drivers side?

It is further forward on the driver side and the motor mount bracket partially obscures it. I'm thinking I might be able to clearance the bracket enough so it would fit but have concerns about weakening the bracket.
Here's what I'd have to cut out of the engine mount bracket for the the driver side port.
Basically removes that dimpled spot on the bracket which I'm worried would weaken the bracket. Plus I'm not sure if the mount would hit it.

Maybe I should just go FiTech or Holley Sniper and just skip all these pesky sensor issues....
Ha! Yeah I don't like cutting the mount either.
