gm V8 question.
« on: March 07, 2012, 04:25:56 PM »
Two of my friends and I are kind of doing a 3-way motor swap.  My friends Mark and Ash both have old Datsuns.  Mark has a 72 Datsun 510 that he's had for a long time, and Ash has a 73 Datsun 620.  Recently Mark has decided he needs a more reliable engine to replace the built L20 currently in the 510, and Ash wants the L20 out of the 510 for his 620. So Mark is going to be buying the KA24DE out of my 240, and is giving Ash the L20.  I have been wanting to build a KA Turbo but the build would have been 12k+ for what I was planning and the reliability would have been questionable.  So I have decided to just throw an aluminum GM V8 into my 240 and call it a day.  I would like to put a 6.0 in it backed by a tko 6-speed so I actually have a fast and reliable vehicle that gets good mileage.

Now for the question, did any trucks come with an aluminum block 6.0? If so, which years?

I don't think an aluminum 6.0l made it into trucks until very very recently.

For what it's worth, the cast iron 6.0 can be had for fairly cheap and we're only talking about an additional 65lbs of weight as opposed to the aluminum block.

I figured it would have been a little bit more of a weight difference. Maybe I'll just pick up a 4.8 and boost the everloving shit out of it.  Hot Rod Magazine made ~1000 HP consistently and reliably with it for not a whole lot of money.

Yeah I thought it would be heavier too, but I remembered seeing something on Horsepower TV and they suggested just going with the iron block if weight isn't a huge concern because the weight difference wasn't much, so I looked it up. Really unless you're trying to shave fractions of a second off your time, 65lbs negligible.

Not that 15 pounds is a big deal, but everything I heard (and my T/A showed it to be very close) is that the iron is 80 pounds heavier than the aluminum. 
That weight is good for almost a tenth of a second at the drag strip. 

And Dewman is right, LS2 is the aluminum 6.0.  Trailblazer SS got it, but no other trucks.

Ah. I wasn't sure how accurate the number was, but eh, close enough.

But yeah like I said, if you're trying to shave fractions off of your time, then the weight reduction of an aluminum block would help... but if that's not a concern nor ever will it be, then the iron block is cheaper and more plentiful. Work trucks and work vans are a very common source. You can find them in the junk yard with a few thousand miles on them, but wrecked in some other way.

Newer body style trucks with the "VortecMax" got the L76, all aluminum 6.0l.

On second thought I can pick up a 4.8 for < $500 with all the wiring harness and pcm. Then I'm thinking twin remote mount holset HX or HY turbos and boost the ever loving shit out of them.

This is when they thought they we're working with a 5.3.
This is after they made over 1200 HP then realized it was a 4.8.
