Ls 5.3 conversion info - The 1947 - Present Chevrolet & GMC Truck Message Board Network

fredscarryall · 01-30-2013, 08:59 PM

I think I am going to convert to a ls 5.3 with a 4l60e transmission in my 50 burb. I'm still going to use the factory frame with the thunderbird/mustang 2 front end.would like to see how everyone is running the radiator hoses,using the Ls power steering pump,using the Ls alternator ,using the Ls a/c pump,what motor mounts ,oil pan and headers work best.i am also using the factory fuel injection and would like to know of a good wiring harness ,fuel pump and if I need the o2 sensor,crank sensor and cam sensor. Any help or pics would be appreciated.

I am going to do this same thing in my 53 Burb too (eventually). I'd like to see too.

You can look at my build thread for some ideas. I have an s10 frame so the factory A/C compressor won't work for me, but maybe it will for a MII.

Well it looks like you will be spending quite bit of time in the LS Swap section of this forum for all the items you mentioned.
I have been reading for about a month and have purchased motor mounts and A/C bracket for my new project LS 5.3 after reading 11 pages of info.
These came from Dirty Dingo
Next big item is a wire harness, and it looks like Howell is going to get the bid for a re flash and a harness.

I bought my wiring harness from PSI conversion. I had an issue that was my fault and the guy was easy to work with and cleared it up for me no charge. Here is the web site http://psiconversion.com/

I made my own more motors and used an F-body oil pan.

Solidaxel thanks for posting that AC bracket I like it better than the one I was going to buy.

Like solidaxel said, check in on the LS Swap section of this forum. Lots of good info there.

Kabwe, anything for you buddy !!

I have built my trucks from information that you and others have shared on this site.

I am thinking I am going to run out of time and money before I finish all my projects !!
