Dipstick Location

In shopping for an engine for my 68 coupe restoration, I find that 350 cu. in. Chevy engines are available with the dipstick located on either the drivers side or the passengers side.  What is the relevance?  Is one a truck engine?  Would the location of the dipstick affect the value of the car?

Most 350 blocks cast after 1978 have the dipstick on the passenger side; shouldn't affect "value" at all, as we're not talking about the original engine anyway.
