VortecMax L76

[guruerror]

I figured I'd throw this out there and see what feedback I get...

I've been 'thinking' about a Duramax conversion for my '05 when I hit 150,000...I'm only at about 80,000 now, so I've got a ways; but I've read through some horror stories on the forum about this, and I hate to ask how much Predator is charging now...

SO...that got me thinking about what would make a more friendly upgrade...something without as many ECM, wiring problems, etc.

In researching the Vortec line of engines I noticed that the 4th Gen Vortec 6000 (L76 - VortecMax) has an 'aluminum block.' Hmmmm...(thinking...thinking)...my science teacher, Mr. Reader, told us that aluminum is 'lighter' than iron...(thinking...thinking)...if the engine weighs less, the truck weighs less...if the truck weighs less, the engine doesn't have to work quite as hard to move the truck...if the engine doesn't have to work as hard my performance and mpg should go up.

I couldn't find exact specs on the LQ4 or the L76...so I don't know the actual weight difference, nor do I know if the L76 would bolt up to everything that it needs to bolt up to...so I thought I'd put this out there and see if anyone had any additional thoughts or information.
