360 stroker how much HP is picked up if everything else stays the same?

Just did this. Went from a 360 to a 418. Same car, heads, cam, carb, headers, gears, vert, etc.
Only significant difference was more compression with stroker.
360 best, 11.26, 418 best 10.77

I ask noted Mopar engine builder Ken Hensley this very question over 20 years ago.
His answer, 3 or 4 tenths.

"Same heads, cam, carb, headers, gears, vert, etc." All these thing will work different with different displacements, rod ratio's, torque, rpm etc.. so it could these part's we're just more suited to the 418.
