Mid 12's for the original 289 Cobras is likely in my opinion. Thats based on what I see today with STOCK 302 replicas. Low 13's is the norm, with any modifications at all your in the 12's.

Generally speaking the original cars were lighter than just about ANY replica out there, and they certainly had more h.p. than a modern stock 302. I'm running BIG letter Goodyears, the traction is VERY good.

An early issue with the 260 Cobras was dissapointed owners when the car did NOT meet the acceleration numbers "promised". Those numbers were obtained by Shelby running a VERY modiifed high horse power 260 and the early "production" cars received a much more mild version. The initial Shelby solution was a lower rear gear.

My guess is a SB will get the hole shot on a big block. But MY big block just keeps pulling REALLY strong well after a 100mph, when the small block starts to struggle. THATS what makes the mph speed so much different while the ET stays fairly close.
