Probably so. 73 340's ran pretty good but they were pretty anemic compared to the 68 and newer ones. 73 was the last year for the 340 and everything got a 318 or 360 from there. The 360's were built like the 340's of that era. Heads, cams, manifolds, etc were interchangeable. The 360 would perform a little better because of the extra stroke. Look up the torque and HP specs to see.
