You have three choices.... well, maybe more, but these are what come to mind.....

* Use the stock in-cab tank with an external pump. You will need to install a return line back into the tank.

* Use an 87-91 Blazer or Surburban tank that mounts behind the rear axle between the frame. These were TBI trucks and already have the fuel pump in-tank, so you can use an inexpensive OEM pump.

* Use a custom made aluminum tank with an in-tank pump.

I hadn't thought about the newer Blazer/Burban. They should fit with the leaf spring truck not having that rear panhard crossmember? Obviously, I could add what ever is needed to make the mounting work. I assume that I would also need to upgrade that OE pump because it was just for TBI and not for SFI.

Good idea, I will have to look into that alittle further.

My truck is a shortbed/leafspring and I used a stock tank and sender for an 87 c-10 (I think they were actually called R-10?). Ordered it from Rock Auto for like $100 I think. It has the baffle/sump for the EP-381 and fits like the original. Only 16 gallons though.

Anthony.

I just finished a 4X4 one, Critter is working on one and I know there is at least another one with an NV4500. I am in Brockton just over an hour away. Most of my build is in a few threads if you search my name for posts (some is in my signature also).

[Juiced06GTO]

Good to hear! I would love to come check it out sometime. I test fitted the motor last week and realized that the motor mount pads need to be moved back about 1 3/4" and the front cross member needs to be notched. I picked up some material so I can get started on the welding, but went on vacation last week so work on it has stopped. I also have most of the harness for the 5.3 torn apart, hoping to get that all rewired by this weekend.

I am hoping to get the truck on the road by the end of august. Thanks for all the great info!

They will fit even with the panhard bar.

I assume that I would also need to upgrade that OE pump because it was just for TBI and not for SFI.

An ACDelco EP381 fits in the 87 truck and 87-91 Blazer/Burb sending units, and provides more than the 58 PSI needed for the LS engines. They run about $70 and are available over the counter at any parts house.

Perfect! That is why we needed this! That is the info I need to get moving further on getting my frame so I can work on getting the engine/trans set in!

Thanks for the quick response too. Now to find a tank, Hmmm?

[glock35ipsc]

Believe it or not, many on here have had good luck (and good prices) buying new at Advance Auto, O'Rileys, and Auto Zone. I got my pair of 87 tanks from rockauto.com delivered for a few $$ less than I could go to town and buy from one of the above three.

Take advantage of the new forum to make a new post with future questions. That way they wont get buried here and others can see them too.

[glock35ipsc]

That's OK. Since this forum opened up, I'm still editing my posts a lot! I haven't quite got the "yo, these engines can be swapped into more vehicles than a square body!" in my head yet.

[smokinstang70]

Can't wait to get some info from you guys.... I have a 71 c-10, a 2006 5.3L & 4L60E, motor mounts, trans crossmember, and a lot of enthusiasm about the build. Hope I can leverage some lessons learned from you guys!!!

Working on modifying my harness as we speak. Also looking for ideas on air filters... using stock airbox or going aftermarket.

Look forward to talking with a lot of you in the near future... and can't wait to see some pictures and follow build threads.

Thanks guys

[Juiced06GTO]

I will start a build thread as soon as I can get back on the truck. I am still trying to come up with ideas about how to modify the motor mounts and cross member....

Good to see this dedicated forum. I'll share my experience with installing a 5.3l into a 41 GMC, mounted on an S-10 frame.

[G&R's57GMC]

I'm at the point of installing a 5.3/4L60E in my 57 GMC. Currently the combo is setting on top of the frame waiting for me to slip it into place and fab mounts.

I'll start a thread on the 47-59 forum on the entire project in the future and post the engine install here.

I've got the EZ chassis swap on my 1951/s10. It came with s/10 to 350 SBC motor mounts. I put LS to 350 SBC plates on the engine. There is a pretty good gap that I'm going to have to shim between the two. I'm not too wild about it. Has anyone ever shimmed up a gap like that on motor mounts?

It did feel good just to see what it looked like mounted up though.
