nothing bug but i was researching the #s on the knock modules because i have an LT4 one and the one that came from factory.
well i found the LT4 one by its part # 16214681
than i searched for the # on my original and it is 16214671 which is the # of the corvette knock modules not the fbodys... just a little wierd, in the manual it says the # for the fbody knock module is 16214661
just a little somehting i found aout my car, maybe it was relpaced earlier by a previous owner, who knows
