1981 Chevy 3/4ton 454

[TexonWheels]

Hey folks, Need some assistance ~
I was inherited this truck from my grandfather in 94 when he passed. He was a contract welder and last known miles was 350,000 with just a valve job and water pump and alternator replaced. I decided to rebuild it back to its original state but ran into an issue after pulling the motor 3 years ago. I rebuilt the motor recently and found the bottom end was still in miraculant shape! The prob I am having is I cannot remember what goes where as for accessories. (I know I should have taken pics first.) All the books and websites doesn't show a complete engine for a 454
Anyone have any input would be greatly appreciated.
