Speaking from direct experience, which 98% of this thread lacks...
I have have a M1 on my current 511" LD with 280@ .050@larger nitrous friendly cam and it is fine on the street woth a 3.23 gear. The big manifold likes fuel compared to the Holley SD that was on it.
As far as getting traction goes that is up to the operator. Experience > regurgitated internet info is a fact of life.
