I would exactly say it was a “mess up”…sorry, I worded it wrong
01 was when the first LS6 came out and it was very identical to the LS1’s…so some mechanics screwed up the organization of the motor line and some accidentally got dropped into F-bodys.
also, my V6 was kind of a screw up. I had a sticking brake caliper and I brought it to the shop and the part number on the brake caliper didnt match the V6’s brake calipers numbers (the one it was supposed to have)…turns out, I had the z28 brake setup from the factory on my V6.
