hi, the oil dipstick hole will be on the drivers side of the motor,on the bottom of the side of the block near where the oil pan meets ,there will be a slight flat area,if you look between the # XXXXX and # XXXXX spark plug hole .,straight down near the bottom of the block ( on the side) will be the hole,perhaps there is a paper plug covering the hole as most rebuilt motors will have that and will more than likely be the same color as the motor ...guy..
P.S. some later motors may have had a dipstick in the oil pan ,but it was usually the 305
