id love to see side profile of the motor mount and headers when you get them done
all right. Let me ask you this. since I'm doing the 5.3, there are plentiful 5.3 iron blocks, but I have been holding out for an aluminum one. I can't make a decision. Should I go aluminum or iron block? What do you think?
I would stay stick with the Iron block unless you want the uber cool factor of an AL.
Iron is durable, can be bored more...
But an L33 5.3 is an awesome little motor...

you mean LS3 . ?
Pretty sure he means block code L33. Which yes, is what I'm looking for.
Aluminum block.
I agree with the cast. Actually, I want to supercharge it, so cast may go in there.
What is the weight difference.

No, GM produced an L33 5.3 motor that was an option in the 05+ Chevrolet trucks. They have 799 casting heads which are reported to be the same as the LS2 heads. Hotter Cam and some other stuff.
A good bit more low end torque and power then the iron block 5.3.

L33
The L33 (VIN code "B") is an aluminum block version of the LM7, and was referred to as the Vortec 5300 HO in marketing materials. Power increased by 15 hp (11 kW), to 310 hp (230 kW), over the LM7, and torque was unchanged. It was only available on extended cab 4WD pickup trucks. Only 25% of trucks made in 2005 had the L33 engine.
L33 applications:
2005-2007 Chevrolet Silverado 1500 4WD
2005-2007 GMC Sierra 1500 4WD
LS1tech has the same story

Some people say it is 100+ lbs, from actual weight and moving them around it's more like 80 if that. block for block.
With FI in your future I would stay iron.
I'm using an L33 in my current project but it's an N/A motor and a track toy.
Also, the 15 extra hp is actually a bit more from what I gather... GM under estimation is back!

People are making 800-900hp on pump gas reliably with the alum ls2 block. It can take the punishment we are throwing at it. My logic on the issue is that it is not much cheaper if you shop around. Premo junkyards are hurting and always need to turn a buck. The most important benefit of the swap is the xtra power of any v8. the second best benefit is taking weight off the front of the front axle. The lighter the load on the front axle the harder we can wheel it.
Kirk,
If you're going to fab your own trans/transfer adapter have you given any thought to incorporating a mini truck transfer gear reduction sandwiched between the 4l70 and LC transfer?

I think he means the classic double reduction tranny, like what Marlin Crawler offers for the min trucks.

From the pics I chose to go with the marks setup to save the time of me reinventing something as good as or better. The marks setup worked out pretty good thus far. I dont see how I could do much better.
As far as a double from a mini like a marlin setup I have two issues. First is the mini truck unit is undersized in my opinion to be installed on a 80 series. Second the length issue would be a challenge to squeeze it inline. I think the marks crawler box that I have on the shortbus is a really nice design and works just fine.
Good point on the significant power difference. My mind started working when I saw the adapter stack and what appeared to be enough room to squeeze a double in there. Granted with the grunt of this setup and a slushbox a double may not be needed especially since you already have a rig for giong slow.

honestly most types of wheeling I see the old V8 did perfect with 5.29's and the 39.5's. having a torque convertor with some hpower makes crawling easy. the 1fz needs the crawler imho bc i doesnt want to whind up when you need the juice. My old mini truck was the same way. So my point is a auto tranny and some horsepower can negate the need for the crawler.
hey there is this guy doing harness for ls engines into 80 series here in australia
