383 = no love

I'm sticking to the test is a bit silly statement, one engine is a big block, they are not the same size cubic inch, the cams are different, new heads,old heads, bigger intake volume ect ect.
I still could see testing a big block 396 vs 383 or a stroker small bock 408 Mopar vs 406 Chevy, to me that would be more interesting.

Obviously it's not a scientific shoot out and a one off. I think the main think to take away from it. It does somewhat prove it's more just the size of the engine not how you get there to a certain extent for the torque curve.
