I just check Chevy.com and looked at the options for the 08 Silverado and saw something intresting,

 

It stated 4 different 5.3L engines.

 

1 Iron block 5.3L with AFM

 

1 Aluminum block 5.3L with AFM

 

1 Iron block 5.3L with AFM flex fuel

 

1 Aluminum block 5.3L with AFM with flex fuel

 

now how do we know if we have the aluminum blocks or the iron blocks, can anyone help me?

 

And did they have the same block options for the 07 and how can you tell?

The block depends on your model. EC got iron block with Al spare wheel, CC got Al block with steel spare, and I'm not sure what the RC got. 2007 has 3 additional engines, gen III Al, iron, and flex fuel (for the classic).

Not yet to lazy, and to dark, truck is about 200 feet away.

 

But ya forgot Zembones said the color,

 

 

Black means irion and silver ( aluminum color ) means aluminum block.

didn't you guys figure that out when you bought it, i mean when i bought mine i knew all the options in my truck including everything about the engine not just the size and horse power rating, check the rpo code list in your glove box.

I had to buy it, brother gave me a good deal, 24k out the door. It had a 5.3L didnt look into the block and what is made from. But i did know about the other options.

you have your insurance card close by? Usually those have the VIN listed on it....or any registration paperwork you might have filed in a desk or something? Look up the motor code from the VIN

Im trying to figure this out, i looked at it but i dont know whats the option code is for what. It would have been simple if someone said the option code on the vin, but Zembones idea is better. Thanks for all your help guys.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
