The engine is a 1973 cast year 318. Upon further inspection the rod and piston assembly that I pulled out have the part number 3418645. The rod set that I planned on using that have the bushing for a free floating wrist pin have the same part number 3418645. The original rods with a pressed pin have a back number of DF116 also MS 304. The ones with the free floating wrist pin say DF56 as well as MS 304. Are these in terms the same Rod other than one being a pressed pin and the other being bushed for a free-floating pan?
The Piston set I am using are stock style sealed power cast pistons.
The engine has a will have a hughes whiplash cam and will not see constant 5000+ RPM its a daily/street car.
