I'm getting things ready to do 5.3 swap, so any info here will be helpful. I think there are a few here that have done it.

bobbo · 02-16-2008, 07:29 AM

I am getting ready to do it as well. A 5.3L in a 69 GMC...I already have the engine/harness/and computer...still trying to work out details with it and transmission specifics as I am wanting to run a 700R4 in it. Will post when I get going on it...

verry easy swappp!!!! probably the easiest ls swap ive done.

Some buddies and I are currently putting a 01 LS1 in my 81 short-wide, and its gone basically well.. I used painless wiring, hooker LS1 street rod headers, and pcmforless tuning.
One of my buddies that helping me with my swap, has a 72 2wd blazer with a 5.3 and 700r4, and his blazer runs extremely well, and could basically be daily driven..

Actually been thinkin of swappin the 454 for an L92 in the 76, or maybe droppin one in the 87 3/4 ton the 454 came out of. Easy to get 500+hp from one of those and you still get good mileage with them. Also easy to change to ethanol, since that is one of my other projects.

I have plenty of buds who have swapped LS1s into stuff, mostly 3rd gen F bodies. The 4L80E would be perfect for towin my project vehicles between Nebraska and Michigan.

The progress I have done so far on my 6.0L swap is here. It is about to change trucks though...

Strange, it isnt on the local boards. You mean we missed someone in Charleston who owned a F body? Unpossible!

Oh a buddy from back home then..

knightlife · 03-13-2008, 05:22 AM

aye... hes from texas, but I wont hold taht against him lol

wildmanaaron · 05-18-2008, 08:28 PM

I put an LS-1 and 4L60E in my Blazer. I had never done a complete engine swap like this before and had NEVER wired an engine before. Do your homework and learn about the swap and it is worth it!

gchemist · 05-19-2008, 06:18 AM

77 with an LS-1

check out Street and Performance at http://hotrodlane.cc/. I think they are a little overpriced. But, they have an arse-load of information that'll help on the swap.
