    I concur, knock sensor more than likely. (if factory)

    Does/did the truck have ESC or CCC?

    Hello,
    What is a ESC or CCC? This is a 1985 K5 Blazer with a new 5.7L create engine. It is carbed.
    Thanks

    e= electronic

    s= spark

    c= control

    and if you have a 2 wire blue plug on top of your carb then you have the electronic cab for fuel control .

    And I may at least a partial mistake in my previous post. CCC on trucks (Computer Command Control) from what we've seen here so far, did not use a knock sensor.

    The original factory truck engine I'd guarantee was a 305/5L IF it has ESC. ESC was used due to the relatively high compression of the 305 with the crappy cylinder heads of the time. Saved the engine in case there were problems, the ESC (via the signal from the knock sensor) would retard timing.

    The distributor is different than "standard" HEI, and there will be a small computer box behind and above your glovebox.
