Re: LS engine swap info
Yes, you would. And that brings other headaches, challenges, or opportunities to learn new stuff, depending on your outlook. I'm also not sure what the "recyclers" are wanting for them. Easy + cheap = 383, me thinks.

Re: LS engine swap info
I have probably over looked it, but I have looked. I am looking for a DIY on the mods that need to be done to the wiring harness for an LSX. I bought an entire truck that I will be pulling the motor and tranny out of, 04 2500 Truck LQ4 4L80E.

Re: LS engine swap info
Check LS1tech.com for wiring diagrams and such. Unless someone posted on here and I missed it.

Re: LS engine swap info
I got all my wiring diagrams from autozone.com under the repair manual section and referred to the guidance provided on www.LT1swap.com. But I don't actually have a running engine yet.

Re: LS engine swap info
my .02 I got all I needed when I did my 5.3 swap from the lt1swap page mention above...it took about a weeks worth of studing the diagrams and reading on the web and about 6 or 7 hours of actually cuting and re routing the some wires \.

Re: LS engine swap info
Great thread and thanks to all.
I'm putting a 4.8 and 4l60e from a 2000 truck into a '51 GMC suburban. It looks like it all fits pretty well except for the pass. side exhaust manifold. I need something that is shorter or longer, to get by the top of the frame rail. What would be a better stock ex manifold? Also, the engine leaked out orange anti-freeze. Can I run traditional green AF in this motor without any issues? I broke one manifold bolt, but it'll come out. What is the least expensive but proper replacement for those? This is a major league cheapo build. And I'm sure I'll have plenty more questions. I got the motor trans and redone harness for $1400 bucks. Which is cheaper than rebuilding a 6 banger. Thanks again.. |

Re: LS engine swap info
You can run regular antifreez (I would try to flush all the dexcool out though)
Prestone (others might also) Makes a universal antifreez that is supposed to work with both types. Some people use Fbody (camaro/firebird manifolds 1998-2002?) I am using trailblazer SS manifolds that hug the block nicely (but mine is 4 X 4) I would just get some manifold bolts from a dealer, parts yard? I use copper never sieze as they are prone to breaking. I use a torque wrench also. Good luck with your swap

Re: LS engine swap info
looks like Dorman makes a TBSS or SSR manifold for under $100. p/n 674785 or maybe the 675525
Do you run washers on the manifold bolts as some are suggesting? |

Re: LS engine swap info
I didn't as I used stock manifolds and stock bolts. After installing everything and hearing how many have had broken exhaust bolts so a month ago I removed every one and put high temp never seize and reinstalled and torqued every bolt except the couple I couldn't get the torque wrench on.

Re: LS engine swap info
I used the stock bolts as well, which don't need washers because they are already a shouldered bolt.
I install with antiseize which is common practice for me with anything aluminum. Steel bolts and aluminum parts don't mix well. I used the 3/4 ton truck manifolds on my swap, they are said to be some of the better flowing manifolds out there as far as trucks go. I had to slightly notch the frame however because they kick out a bit, which is what helps them flow as well as they do. I sent mine out to be extrude honed as well. |

Re: LS engine swap info
Who knows about stock exhaust manifolds? The original truck (2000 4.8) manifold sits just above my frame rail. I'd like it to be shorter by at least 2 inches, or if it tucked tighter to the engine by about 2 inches. I'm looking at the SSR manifolds. They SEEM to be shorter, but I have no way of knowing at this time. Dorman has the repros for about $140 or so with the gasket and studs. The GM Dealership can get me a new GM part(SSR pass. side ex manifold) for just over $80 bucks. (No gasket or studs).
Can anyone tell me if the SSR manifold is actually shorter than the original truck manifold? Thanks. (1951 GMC suburban w/ 4.8 and 4l60 and '65 truck 12 bolt going in) |

Re: LS engine swap info
I used the Sanderson Shortie Headers CSLS1 and have not had any issues at all, no leaks not fitment issues at all.

Re: LS engine swap info
I am looking for a cost effective header. Where did you purchase. I do not prefer thin headers.
Did you do the duals or dual to single? Did you place the 02 sensor right after the header? |

Re: LS engine swap info
No one makes a long tube header for the LS 4x4 blazer swap.
I looked around and only found shorties, which didn't interest me. They aren't worth much power over the truck manifolds, which are actually a decent flowing piece, said to be one of the best LS manifolds aside from the vette. For $500 for shorties I elected to just use the truck manifolds. I simply made some exhaust pieces out of mandrel bends to connect the manifolds to my current exhaust system, which is a dual exhaust. I then welded in 02 bungs right after the exhaust manifolds in a convenient spot. At some point if someone comes out with long tubes, I'll swap over. |

Re: LS engine swap info
.....most guys are using long tube camaro or chevelle ls swap headers..they seem not to hang lower than the frame...but if it's a 4x4 it wouldn't really matter anyway?

I'm not sure what year camaro you are speaking of. I have 2 4th gen camaro's here with LS engines and long tube headers in both. The driver side header collector has a weird kick out toward the rocker on both cars (to clear bellhousing) at about 20 degrees. That would be nearly impossible to make work in a 4x4 blazer when you have a pair of crossmembers and a transfer case to deal with. My chevelle and 1st gen camaro doesn't have an LS in either, so I have no idea what those swap headers look like. Guess I'm just not willing to experiment with a $700+ set of headers...but I'd plunk the money down in a heart beat if something out there on the market worked for certain. I was hoping someone would chime in with pics that has actually done this but it doesn't seem to be a popular swap as of yet? |

Re: LS engine swap info
How about the Doug Thorley headers for LS swaps into 67-72s? I think part # 324Y-C. As for cost effective, that's a different matter.

I prefer at least 1 3/4 for a small LS, or 1 7/8 for larger LS. |

Also, tri-y headers are great for low and mid range power they just lack a bit of the top end that long tubes have. Since I don't plan on running my truck at 6500rpms all the time I think they'll be fine. Posted via Mobile Device

Re: LS engine swap info
Would you like to share your contact information for Mike? website, vendor link, etc?
[QUOTE=Billett;6092551]Actually they do sell larger versions. 324y-c is the 1-5/8" version but 323y-c is the 1-7/8" set. I called up Mike just last week and ordered a set and he gave me a great deal on them.QUOTE]

Re: LS engine swap info
I am also very interested in what headers will work on a 2wd, I'm seeing ya'll are talking about the 2nd gen LS headers and Chevelle headers, but what brand are ya'll referring to?

I used a 98 camaro driver side manifold and truck passenger side manifold. I installed an 02 bung on the passenger side as the manifold did not have a provision. The camaro dirver has a hole provision for the 02 sensor already on it.
I finally got my LS running with 0 issues. I can't believe it fired up at the flick of the key. Now for all the other fun stuff like brakes, shifter, and wiring. Last edited by grennberet02; 11-05-2012 at 02:47 PM. |
