5.3 internals
You are not talking about weight matching, are you?
do you have the original rods and pistons that were on the crank you are wanting to put the other rods and pistons? If so, weigh them. They weigh close to the same, you are good. Btw, when I built my 5.3, I used H beam rods and forged pistons….my machinist said the weights were close enough I could have ran it without balancing.
Engine 1
. Engine 2 have good rods and piston bad crankshaft. All parts are OEM originals. I just wanted a second opinion on swapping without needing balancing
