Re: Project Greenbrier

Couple of the 4l60e installed. I converted over the original Suburban 4x4 trans to rear wheel drive...I'm using the "truck pan" from the Sub.

It sits kinda' low...but it's not any lower than the F-body oil pan or trans cross member. I think it will be fine.


Original "double hump" cross member fits this app like a glove. Used two original holes in the frame for the front two holes...rear two were about 1/4 of a hole off. Quick trip through with a 3/8" drill bit and we are bolted up.

Re: Project Greenbrier

Little more progress on the ol' ride...

Napa radiator #NR2700...$121.34

NAPA lower hose #7499...$16.21

These parts fit like gloves...absolutely bolt in no mods to anything...

Last shot is of my exhaust...don't know if I'll leave it like this or not...

Re: Project Greenbrier

Decided to go with the Windstar fans...this fan module fits like Chevy made it for the Chevelle...


These are posted in the lS engine section under LS cooling options...


I don't mean to cross post...I just figure some of the guys interested in this might not venture over there.

Re: Project Greenbrier

Hi Mike,
Nice work and set up. How do you think those Windstar fans would fit in a regular Small/Big Block cooling set up with a non-plastic tank radiator?
Keep it going,
Tom

Thanks Tom...

I think they work fine with the "big" radiator. Thunderstruck507 and Sinister are both using them with 3-core stock Chevelle radiators.

They are the one's that suggested I look into this fan setup.

For reference purposes in my research I found these are suppose to flow a tad over 4400 cfm...

Re: Project Greenbrier

Liking the thread. I actually just bought a 72 concourse and am thinking of doing an LS conversion and have been reading everything I can. What did you decide to do for your gas tank issue? Seems like in the wagons that may be a major issue. Looking forward to see the outcome.

Thanks Steve...funny you should ask about my fuel system. I started on it last weekend but didn't make much progress...the heat and humidity up here has been kicking my butt. (We're not use to this kind of weather this late in the year up here in the Dakota's.)

I'm going to use an in tank GM 281 pump. Build a hanger off my stock 3/8"s line and reinforce it...and add a another 5/16"s return line to my tank somewhere...and...try and make it all fit in the original access hole.

I'll try and have some pics next week I hope...

Re: Project Greenbrier

Mike, the 71 wagon has 2 lines to the sending unit because of the increase in emissions, I believe. I just removed mine and found that the resistance sender for the fuel gauge is FUBAR ( https://www.chevelles.com/forums/showthread.php?t=499953 ). I found and have a "new" used sending unit coming from a yard in Washington State. Would a 71 unit be of use to you because of the 2 lines? If so, either you could find one at a yard in your area or I can send you my old one for the price of the mailing. This way, you would not have to fabricate a return line in your tank. Email me if you want it.

Re: Project Greenbrier

Mike I recently added an in tank electric pump to the Nova using the stock sender. I added a line in the sender for the pump and used the original line as a return. It was easy to do, only took a few hours after spending a week engineering it I plan on doing the same to wagon tank.

Thanks Ralph...I'll check tomorrow on my line situation.

I think my tank is plumbed like yours. I've been following your sender thread.

I may take you up on this anyway.

That's excellent...do you have any pics of your work???

What size were your lines??? Were there just two???

I think I have three like Ralph...3/8"s feed, 5/16's return and either 5/16's or 1/4" vent.

Re: Project Greenbrier

Mike this is what I started with, 1 line 3.8" diameter. The pump used was from an 82 Corvette.



A 1/4" hole was drilled in the plate for the new pipe. A punch was used to enlarge the hole because it also tapered it like GM did.









Unfortunately I did not take any photos of the finished set up. Another small hole was drilled for the pump wires. The strainer and a rubber fuel line were attached to the pump. The length of the line was adjusted to allow for slight pressure on the stainer against the bottom of the tank. Now to get it all in the small hole in the tank the pump with the hose attached was lowered in, then the sending unit was installed. Both were pulled up and the fuel pump hose was attached to the new pipe. Then the assembly was lowered in and the lock ring installed.
If running fuel injection a reservoir will need to be installed too. I am working on a tank modification for that too but it requires enlarging the opening for the sender. With the larger opening the installation is the same as later model cars and there is enough room to get into the tank to install a reservoir cup.
A few photos of the work so far.

Here are the 2 openings. Both were cut out of the tanks and the larger one installed in the Nova tank.



The Nova tank with the hole enlarged



The larger lock ring assembly installed



the mock up with a junk sender installed.

Re: Project Greenbrier

Found a photo of the pump hanging on the sender. To make it work the pipe was shortened and a longer hose used, but it shows the style pump used. That style is available from 14 psi up to 80 psi.

Re: Project Greenbrier

Got a little R&D done on the fuel system...I think I'm going to leave the original tank opening alone for now...I think I can make things fit with a little work.

Modified sender and pickup...









Pump and float...



In we go...
