Some good info for Aluminum Rods..Ignor the magazine but read the article
I would like to have some confidence on when the aluminum rod "must" be changed. I don't normally pull the engine down every season unless I must or I'm changing something.

For instance because I broke at the end of the season and It's going to be mid season before I can get the blower motor back in, I'm going to put my 572 in the car. To run mid 4.60's I hope,
I am replacing the rear gear (3.90-4.30), shorter(Big Bubba to Little Bubba)changing converter from the blower converter. Otherwise the car would have got a new set of tires.

I guess instead of aluminum rods I could just go with a set of killer steel one's.

It's a dilemma..
