After seeing these pictures though of the "cast" crank or just a different version of the crank that came in a 3500



It looks nothing like what I have and the stunning comparison between my current crank my old pics of the 7484 crank I had, Other 7484 photos as well as other photos of 5299's I just feel they are created equal.

GM Corporate directed me to call my local GM service department for the answer... lmao

I'm not surprised and I'm sure they will read you what it says in the 05 Malibu manual I found the specs in...

"The crankshaft is forged steel - some applications use cast iron, with deep rolled fillets on all 6 crankpins and all 4 main journals. Four steel-backed aluminum bearings are used. The #3 bearing is the end-thrust bearing."
