Hi!

I recently had gone through this exact dilemma. I have a CR with a ERA correct 289 but wanted more than the 274hp. I did a lot of research with history search. What I found out was the Cobra handled better with the 289 over the 427 according to the original drivers that dominated back in the 60’s. Caroll Shelby jumped to a 427 to keep up with the Corvette’s. In a documentary the question came up to Caroll if you had a choice of Cobra what would you want. Carroll said a 289 with an automatic would be his choice. I was surprised but I final figured out why he said it. The 289 was the perfect motor for the AC for SCCA racing. For street use the 427 was the best choice. I ended up going with a 347 Stroker from Prestige Motors pushing 483 HP and 434 TRQ. Waiting for the motor to be shipped to me this winter. I felt that I was able to take advantage of a small block pushing big block hp. The automatic piece that Carroll spoke about was more about always having control of the drivetrain all the time and never a break in between gear changes.
