383 vs 400

Where do all the "there's no replacement for displacement" guys go when 360s and 400s are being discussed?

...and I completely disagree about any "walking all over".

Swap nothing but the motor (I did) and see for yourself (as I did).

1970 HP 383 vs 1977 400 from a van.

In the same car with the same gears, it was hard to tell the difference.
