I looked at a Cobra prior to purchasing my Kirkham and that Cobra had CSX block number 188 (or something like that). It had leaking problems at the rear main seal, I think due to not having a drainback hole, but I'll let Rick Lake and the rest of the real experts correct and/or expand on that. RIck Lake has two early CSX blocks, if I remember correctly.
