Which Knock Sensor & Memcal??

[robertisaar]

The memcal/ks issue has been discussed a lot of times at TGO. You want the KS that matches your cylinder bore (or as close as possible).

thats what i was getting at, thanks for the confirmation.

And what about the filter?

I am not 100%, but I there was a few guys trying to modify the filter for whatever reason and they said the only differences were from v6 to v8 filters (not sure if that's f-body only though).

I would gather that if the KS part numbers are the same for the iron and aluminum headed engines, then the filters would also match. I took apart the white OBDI-swapped Camaro before getting too far into the tuning, but it appeared that the 3.4 KS was working fine with the Lumina memcal (don't know if it was a 3100 or 3400 though).
