pros and cons to the LS1 Alum. block?
it's been suggested to me that aluminum engines aren't so great before I bought this car I did some reading and thought that it was pretty cool.
there's a non aluminum ls1 isn't there? that goes into other GM cars/trucks?
I'd love to hear what all the vets here have to say about it, teach me please

I'm no mechanic, but I do see what others are doing to their cars. I'd say the pro's and con's are probably negligable for what most people are going to do. If put on the spot I'd say go w/ the aluminum. It's lighter, and you've got people making 600+ HP and running 10's w/ them. Just my oppinion. It's worth what you paid for it.

Then how come they run hotter if they "run cooler" They do disipate heat quicker, but the motor takes heat in more. This is why many ALUM block cars have oil burning issues. Just going off of reference, I have only heard this, and seen this for the past year or so. Everyone had oil issues that were eliminated when switching to the cast iron.

They do not "burn" more oil. The cylinder sleeves in the aluminum block are still cast iron. Therefore, the ring/cylinder contact surfaces are identical. The main complaint about the LS1s using oil is related to the PCV system sucking oil into the intake manifold. You should install a catch-can on your PCV system to greatly reduce this common LS1 characteristic.
