Oil dipstick for 73 340

[cuda-cable]

I have  a dipstick  #3870265  from  a 77 Volare 318........it  appears  to be too long ?as in  oil  shows  in excess of  full  by  fair  amount. I'm  going  to drain the oil from  my  340   and  put  in a measured  amount  with  a new filter.I've  never run this engine  so noy sure how  much  oils  in it....believe  they hold  4 qts  plus  the filter?   Is there different  lengths  of  dipsticks  on  small blocks.....if  so which  #  do I  need........thx.......

Different legths on some aftermarket dipsticks.   Fill it up with 4 quarts, start then shut off to fill filter, them mark the new LOW level on the stick. Add the 5th quart, then mark the new FULL mark on the stick.
