Thanks, the shifter is out of an 89 Blazer and I don't have hydroboost. I haven't actually had a chance to get an interstate milage reading yet, but I am planning to take it on the interstate over Xmas. I will try to get a reading and I'll post it.

91 and up xjs have the ecm on the side of the drivers inner fender and I've never heard of them having any problems and haven't heard of anyone moving it. I have a 87 so it's inside where I like it.
What is the smaller computer on the firewall? I thought it was the ecm and was diggin it. Also what does the the throttle body warmer do?

The smaller box is the control box for the electronic gas pedal. The throttle body warmer is to keep the throttle body from freezing up in very cold weather. It is fed by a small coolant line from the radiator.

It can run to the radiator or you can drill and tap the water pump housing. Like this:







These Gen III GM engines are a thing of beauty and efficiency. They run so smoothly and are true works of art. My favorite part is the individual coil packs on the valve covers and how clean the spark plug wires are. No more snakes running everywhere. And no giant distributor to deal with.



The only strange thing to me is the extremely small oil filter. Looks like something off a Honda Civic.

That is another great way to run that hose and I completely agree with you on the filter. lol. I do love the engines though and with some of the mileage #'s on them, I have a hard time worrying too much about the small filters. I have considered trying a filter from a 2000 5.3. That's what's in our Yukon and the filter is taller. The block is the same, so it seems like it should work. I just don't know if they had some reason for the smaller filter and haven't really looked into it.

This is the second 5.3 swap on here, is there a website where you are posting more pictures or maybe doing a more detailed write up? I was going to go 6.6L Duramax but the money involved is more than I want to spend. The 5.3L Vortec seems a more reasonable replacement and a little more straight forward.

I'm sure they wouldn't have made it for nothing but wouldn't the heat from the engine be plenty to keep the TB warm?

Heres a picture from the torchmate buggy on pirate which looks like it has a shorter oem aluminum pan thats even with the dinky oil filter. Maybe the factory pan setup was why? I believe they got that out of a newer gto.

The small filter must be fine. It looks dinky, but I am sure they wouldn't put so much effort into the Gen III motors then slap on a useless filter. It definitely shows how efficient and clean running these engines are though.

I have thought about doing a more detailed write-up at some point. I wish I had taken more pics during the build of all the detail work, but I think I can get enough together to get the point across. Now all I need is some time and to have not forgotten what all I did. I am always happy to answer any questions though. If I get it done I'll let you know.

You would think so, but like you said, they must have had a reason. I'm sure it's not much of an issue unless you're in the coldest of places, but I figured it wasn't that big of deal to hook up, so what the heck. I do have to say though, my 2003 Silverado's throttle body stays pretty cool to the touch when it's running.

My next FSJ build will hopefully get a 6-liter ls motor with a 4l60e. I could have had much more power, better mileage and reliability with the Beater had I done that instead of the 401. Then again, I don't care about nostalgia / keeping vehicles original, and all that stuff.

Why a 4l60? Its strong but not enough to handle extended use with the 6L. Why not a 4l80? Its like th350 vs. Th400.

both will be fine for what I would use it for, either or. I'm done with higher horsepower & the idea of racing, and don't want to go crazy off-road anymore. Mostly light trail riding, some obstacles and just sight-seeing.

This is merely a suggestion, but unless your doing some heavy towing I would just do the 5.3 if you are looking for fuel mileage. Everyone I've known with the 6.0 has been unhappy with the mileage and the 5.3 can actually beat it in the 1/4 mile if they're both unloaded. The only time the 6.0 really shines is with a load. The 5.3 has PLENTY of power for daily driving and actually doesn't tow bad either. Just wanted to throw it out there.

I already had a 5.3, and would rather get the 6'er on the next go-round. But, it would all come down to what is available and what the prices are if / when I'm ready to build another. Hell, it's taken me what, 6 years on the Beater and I'm STILL not driving it?

I got all my hose filter and connectors from Summit Racing http://www.summitracing.com/ I used 6-AN hose. If you call them and tell them what you are doing, they will hook you up with all the fittings that you will need. I used their filter (SUM-230118). If I remember right, you need 3/8 connectors for the fuel rail inlet and 5/16 for the return line. Same connectors on the fuel pump. I would definitely call them instead of trying to order online. They will know what you need to make your system. Do be ready for some major sticker shock though. Mine cost over $400.00 for everything I needed. There may be some cheaper alternatives.

updates? been too long need to see more. I am getting ready, Rebuilding a 5.3 now 5.7. and rebuilding the 4l60e and np241 before the wag gets torn down. But I would like to see yours done before I dive head first into this. Your write up has been very informative.
