Thanks for all the comments and help. It seems like the next step is to get acurate #'s off the block, heads, and intake. I will attempt that on the next moderately warm day we get here, and post them at that time. Now that I know where to look for the casting number for the block (thanks Wayne), I will, but will I also need the serial #? If so, where would I find that? Sal's comment makes me think that there may indeed be a discrepancy between what we thought we have, and what we actually have. Was there a Cobra 289 produced in 65, and therefore possibly in a 66 car? If so, that could explain the notion that it's a 1966, Cobra 289. Thanks again for everyone's help! Mike
