318 - 340 Same Torque??

I had a 1968 Barracuda with a 318-2, and I transplanted a 273-4 from my 1966 Barracuda into it. I ran the car at the drags with both combinations and they ran pretty much identical times. The 318 had more low end and the 273 had more top end.
Been preaching that for years.....
