It's awesome how many LS swaps we have going on right now. We're all going to have to take a road trip and meet up in the middle some day so we can all bask in the glory of our newfound LS POWAH!

Well......... I haven't yet. I will put it on my engine stand and roll it over to get the bottom.

Well the weather is warming up with no rain and the guy that is helping me pull the old motor....... OK I'm helping him, his mother is in the hospital and not doing very well so I sit and wait. Here are a few pic from my day at the local pull-a-part, got all this for $25.00 and the old guy thought he was ripping me off! I have been pricing this stuff on ebay and I could not get the air cleaner for that and this one also has the MAF sensor. Is any one else using the stock fuse box from the donor truck? Do I need this or is there something else that I should use?

Man you got a smokin deal on the parts. Our local pull a part doesn't get this stuff ever, if it does the good ole boys get first dibbs on everything. I am considering using the stock fuse box if possible. Keep it up!

[glock35ipsc]

You will only need to add 4 fuses at most, so you can just add a simple 4-gang fuse block. They are cheap and small, they only take up about 1.5" x 4" or so.

And yeah, you got a heck of a deal for $25!!

Thanks Bob.... I knew if I asked, you guys would have the answer. Not much is going on, getting the last few parts, temp sending unit for the p/s for my gaugeand few misc parts. Still not sure about the original oil pressure sending unit, was told that if you do not use it it would give a low pressure code in the ECM and shut down the engine. Do you know anything about that? Think I am going to tap the oil cooler line fitting and use that.

Hey guys I called Performance Online about my fuel tank today. I was inquiring about an intank fuel pump they said I would have to use an inline pump because the was not a sending unit/fuel pump for this tank. any suggestions on how I could use an intank or which inline to use? If you look at the first pic where the sending is it looks like a fuel line coming out of it but it's not, mine just has the red wire that hooks to the gauge. The fitting to the left is a return and the other (feed line) is below the return line at the very bottom of the tank. Thanks for your input!

Thanks Alien! I have a Holley TBI on the 305 I have in it now. It has an external inline fuel pump. I think I am going to just replace it with a high pressure inline pump for the fuel injection. I have steel lines running to the engine bay so all I need is to use FI rubber hose or steel braided to the fuel rails. Any thoughts on which inline pump to use?

[79gmc5.3]

Little progress. Got the D/S Battery tray so I can mount the stock air filter box like soule64 did. I keep telling my wife that I am finished buying parts and then......... I read a post of another swap and the next thing you know......... the UPS guy shows up at my front door!

[79gmc5.3]

Hey guys I have been looking at inline fuel pumps. What psi rating do I need? Seems like I heard that these LS motors run at 58 psi it that correct?

[camdNsprayd]

Yes u need atleast 58 to the rails.

I used a walbro I think the model is the 394 works good,, I heard people complaint about it being noise but,,, I hooked the pump directly to the power for a little while so I could check for any possible leaks and with the truck's engine off and is not loud in my opinion
