What do you think about this statement.........

EFI
Roller cam
More uniform block casting
Cyl head flow
More efficient chamber
Any others?
Other than valvetrain, I don’t think any big differences in oiling

Edit; short block specification came in as I was writing

You can put EFI on anything. Doesn’t make it better.

Same with a roller cam.

I don’t know how many magnum blocks you’ve machined, but they damn sure are not better castings. They suffer from core shift and everything else.

Flow is over rated.

The chambers are not more “efficient”. The magnum uses the same timing or within a degree or two.
