Mopar Engine Weights

My comment is limited in scope. I am only referencing the Dodge Hemi/Poly group, particularly the 315-325 c.i. based on my personal experience working on them. I have not cross referenced my observation against any other established reference source yet but am attempting to do so now. I have a 315 Poly on an engine stand but don't have means to weigh it. Poly and Hemi use the same accessories. The only differences are heads, pistons, cam, valve train complicated with second rocker shaft, valve covers, intake manifolds and carburetors.
No way a poly version is heavier than its Hemi version within the Dodge division's first v8 offering.
