I have never heard, or felt the sound, of a small block that was the same as a big block. Now, I firmly believe you can make a SB just as powerful as a BB, but you can never make it sound the same, anymore than you can make a small bell make the same sound as a big bell.  |
Some of the difference in sound between various engine makes results from differences in the firing order. I don't know if a SB Ford has the same firing order as a FE - probably does. And then compression and cam timing and exhaust size/configuration contribute enormously too. |
