1973 C20 Cheyenne Super 454

[RPOZ11]

My simple thread project.
Been working this truck periodically over the years.
Threw a GM Nylon Timing Chain thus having to rebuild the 454.
I set aside the factory original 289 block and 7416 crank.
Picked up a used block and std/std cast crank and began the rebuild.
I reused the original 049 heads, leaving the stock valve sizing but added hard seats.
Retained the original low plane cast iron intake and slightly restored/rebuilt the Quadrajet.
Cam is a mild .475 lift with 112 centers.
Added the Thorley Tri-Y Headers.
Added an aftermarket aluminum water pump.
Harrison 4-row radiator rebuilt.
Turbo 400 is rebuilt now with a slight shift kit.
Complete rebuild of the drive shaft.
A few years back I had already installed the 3:21.1 gears and added a new Eaton Posi.
Will hopefully fire up this motor with in the day here.
Here is a pic of the 454 rebuilt and installed.
Exhaust is a simple build; nothing fancy.
