highrpm · 02-15-2007, 10:04 AM

Im getting ready to start converting my 70 Suburban to a 6.0 Gen 3. Looking for suggestions on motor mounts, headers, stand alone wire harness, pictures from anybody that has done this already.

Thanks

www.pacificfab.net mods harnesses and ecms. Phone number is on the site and Kevin is very knowledgable about the swaps.

I have ECE motor mounts. My 5.3 sits nice with the ECE mounts. I do not have the wiring yet but I am planning on getting it from Speartech.

shifty · 02-15-2007, 04:20 PM

See signature. 12-13 pages of writeup on a '01 LS1 5.7L, lots of items probably apply to yours.

Search feature is your friend. Good search term: GenIII

ls1tech.com is full of people with hybrid trucks like mine, like what yours plans to be.

highrpm · 02-16-2007, 04:00 PM

Tried the GEN III search dosent ever come up with any results.
Shifty I see in your build thread you switced from a 6.0 to a 5.3 was there problems with the 6.0, and where did you get your headers.

shifty · 02-16-2007, 05:11 PM

Stop searching "Gen III" and start searching "GenIII". That space between "Gen" and "III" is the difference between 'no results' and 'lots of results'. The forum search feature ignores 3-letter search terms, so if you break it into two three-letter search terms, you're screwing yourself.

I just want to be clear here, I used a 5.7, not a 5.3 or 6.0, if you check my last post it's listed as a 5.7 as well

. I wanted a T56 tranny, I did not want an auto tranny (although the install would have been HELLACIOUSLY easier), and wanted to buy a engine/tranny combo that was already mated together from the factory, so ... since I've never seen a 6spd truck, what I got is what I ended up with!

The performance numbers for the WS6/LS1 drivetrain I bought were more what I was looking for, versus the truck engines. The 6.0 has better buildup potential for big HP, but that's not what I'm going for, so .... LS1 out of a TransAm WS6 it was ...

Does anyone make motor mounts for the 6.0L into 4x4 trucks? Looks like ECE only has them for 2wd

billyjo · 02-19-2007, 10:38 PM

I can tell you from experience that the ones from ECE won't work on a 4x4. I used the ones from S&P and they worked fine.

Bill

Madbomber88 · 02-23-2007, 08:20 PM

Ok, I this may be a stupid question, but what is S&P?

68 short step · 02-23-2007, 08:45 PM

Bill

which mounts i n particular did you use billyjo? he ones that bolt to the 4 6.0 motor mount holes and have the 3 bolt pattern ahead of the stock mounts? Reusing one of the block mounts? Did they get into the a/c comp?

billyjo · 03-11-2007, 08:10 PM

Those are the ones that I used and I was able to get the A/C compressor in although I haven't tried hooking it up yet. I've seen some pics of fitting that looks like it should work. I'll let you know when summer gets a little closer.

Bill

onetonk5 · 03-11-2007, 08:40 PM

Billyjo....thanks for the info....i knocked a couple spots off the a/c bracket today and got it to fit..wish i could mock it up somehow before i pull my blazer apart.

late68 · 07-16-2011, 11:22 PM

Did you ever get any part #'s for the headers???

bruin_d · 07-16-2011, 11:35 PM

I would hope so. If he didn't find any for 4 years that would really suck...

late68 · 07-16-2011, 11:39 PM

Ha wow!!!!!!!!!!!1 I didn't even notice how old this thread was, I was just browsing around.... LMAO

eagleuh1 · 07-16-2011, 11:59 PM

LOL. Old but good.

eagleuh1 · 07-17-2011, 12:18 AM

He should be "done" with his project by now. Hmmm, lets see. He can't seem to finish any of his projects it appears. LOL.
