Joe sorry for the typo...they SHOULD be worth only as much as a SS396 (again I was refering to a L78) or a Z28 with the same docs..I'm sorry but I've owned quite a few Camaros (I'm actually more of a Camaro person then a Chevelle person anyway) everything from Z's to L78 and a couple of L89's, along with what I think MIGHT be a COPO, but as far as protecting my investment..I'll take the LS6 anyday..usually better overall factory paperwork and IMO therefore a greater chance or being legit all things (matching numbers, condition, etc.) being equal...
