Dropmember Rear 63-72 Spy Pic
 

Well... the rear Dropmember for the 63-72 chassis will be available shortly. Here's a spy pic.

You outdo yourself again. Incredible work as usual, I'm excited to see the finished product.

Re: Dropmember Rear 63-72 Spy Pic
 

When and how much? And whats included in the dropmember?

Re: Dropmember Rear 63-72 Spy Pic
 

Nice!

On a side note..... I attempted to slide the LSx into the truck tonight. Using some plates that have been scribed w/the typical 'LS to sbc' mount orientation, the drivetrain is pretty close. The 4l80e required removing more of the trans tunnel than I had hoped & I'm thinking I might need to get a f-body oil pan for better bottom end clearance for servicing entrance/exit.

It's a good thing these motors don't have distibutors @ the back of the manifold. The fit is tighter than my wallet ;) .....

Re: Dropmember Rear 63-72 Spy Pic
 

hmm. that look's vaguely familiar :lol::lol:

Re: Dropmember Rear 63-72 Spy Pic
 

Not nearly as much as I am ;)

Re: Dropmember Rear 63-72 Spy Pic
 

Very Nice!

Re: Dropmember Rear 63-72 Spy Pic
 

Wow... maybe I need to changes the plans for my truck, or... even better, buy another one! :lol:

Nice work Nate!

Re: Dropmember Rear 63-72 Spy Pic
 

cool! what kind of link setup will come with it?

Re: Dropmember Rear 63-72 Spy Pic
 

Looks awesome:D

Re: Dropmember Rear 63-72 Spy Pic
 

It will use the stock trailing arms, IIRC.

Looks awesome, Nate.

Re: Dropmember Rear 63-72 Spy Pic
 

looks good can't wait till this is released to be ordered.

I would imagine the rear link set up will be like the 73-87 kits Porterbuilt makes. pics of the 73-87 kit are on the attached link.

Re: Dropmember Rear 63-72 Spy Pic
 

Lookin' good! 'Bout time :lol:So, you're using an off the shelf adapter plate instead of the PB plates? I would definitely recommend the F-body pan; from test fits in the Blazer, I would say it is a necessity.

Re: Dropmember Rear 63-72 Spy Pic
 

So it's a bolt-in notch/bridge?

Re: Dropmember Rear 63-72 Spy Pic
 

I have the sbc DM because that's what was installed in the truck when I made the purchase. I was looking for a 5.3/4l60e for my 74 when I ran across the 6.0/4l80e & figured it would be great for my Beater/tow vehicle. Nate & I have discussed possible options. He'll be working on something on his end & while waiting, I figured I would attack it from mine.

I made 'adapter' plates that are bolted to the LS block & prepped them for both the 'stock' sbc location as well as the 1" set back. After my initial attempt last night, the sbc holes in the plate were very close. The issue I did run into was between the height of the truck intake & the depth of the truck pans sump it was very difficult to get a confirmation that adapter plates will work.

From info I found via the net, the f-body pan is 3" more shallow vs. the truck pan. What I'm trying to confirm @ this time is specifics on the Caddy CTSv pan. It's very similar to the f-body pan dimensionally & apparently uses the same windage tray as the trucks (which means less stuff to buy/mess with).

Re: Dropmember Rear 63-72 Spy Pic
 

wow! nuff said

Re: Dropmember Rear 63-72 Spy Pic
 

You will need the F-body pan for sure... and the F-body pick-up tube. The windage tray can be salvaged with slight trimming.

Re: Dropmember Rear 63-72 Spy Pic
 

This configuration was originally destined for trailing arms... BUT it looks like a four-link makes a lot more sense.

Re: Dropmember Rear 63-72 Spy Pic
 

That explains a lot. I was wondering if this would work- glad you're guinea pigging it for us!
The overall height will be the same. The supplied motor mounts from PB are the same for LSX or SBC; the only difference is in where the mounting tabs are welded to the crossmember.
The truck windage tray can be modified to work with the Camaro pan. The CTS pan may prove to be unobtanium. Though the F-body pans don't exactly grow on trees these days...

Re: Dropmember Rear 63-72 Spy Pic
 

Frizzle-

It is a bolt-on... 100% just like the 73-87 kit. This pic is not of a finished piece. Just a teazer shot.

Re: Dropmember Rear 63-72 Spy Pic
 

My logic is that I most likely won't be the only guy that upgrades to a LSx drivetrain w/the rising costs of petrol.

How much farther forward are the LSx motor-mount tower tabs on the c.member vs. the sbc tabs?

Re: Dropmember Rear 63-72 Spy Pic
 

Does this mean the final configuration is TBD?

Re: Dropmember Rear 63-72 Spy Pic
 

:metal:

Re: Dropmember Rear 63-72 Spy Pic
 

They're actually set back a bit. Looks like ~3"; I haven't had one of each to compare. It looks like the rear tab is in virtually the same spot... Here's a photo comparison: SBC(top), LSX(mine,bottom)

Re: Dropmember Rear 63-72 Spy Pic
 

Since we have seriously thread-jacked you, Nate- getting back on track...

-What will be the advantages of this system over the KP setup?
-How will it compare cost-wise?
-When can we see some more pics?

Quit goofing off on the internet and get back to work on this thing! :lol:

Re: Dropmember Rear 63-72 Spy Pic
 

Nate You Make Me Sick!!! That Is An Awesome Product, Now I Have To Think About Getting It!!

Re: Dropmember Rear 63-72 Spy Pic
 

Agreed..... My apologies Mr. Porter.

Re: Dropmember Rear 63-72 Spy Pic
 

Very nice!! Keep up the good work!
We all wana see it laid out :metal: :lol:

Re: Dropmember Rear 63-72 Spy Pic
 

I am not quite sure as to all the advantages/disadvantages when compared to the KP kit... the KP kit isn't being produced yet.

I do know that my kit will get less travel. I am setting mine up for right at 8" to match the front, and it will run a sleeve bag over the axle. The KP kit, I assume, would get somewhere between 10" and 12", like their square body kit.

Another potential difference is that the Dropmember Rear will be 100% bolt on, while I believe the KP kit has a weld-in notch.

As for pricing... mine will run $1999.00 for the complete kit. Complete Kit includes: Notch,trailing arm crossmember (without tabs for trailing arms!), four-link, bags, shocks, panhard bar, all hardware, carrier bearing support bracket (two-piece driveshaft needed on this one), instructions, and templates (for cutting the frame).

More pics to come later in the week.

Re: Dropmember Rear 63-72 Spy Pic
 

No tunneling of the cab. I like that idea. :cool:

How tall is the notch? Set up to lay on a 30" tire like the 73-87?

Re: Dropmember Rear 63-72 Spy Pic
 

This one is set-up for a 30" tall tire as well.

Re: Dropmember Rear 63-72 Spy Pic
 

Dang it now I HAVE to upgrade to 22's .:waah: I figure my 20's are barely 27" tire diameter.
Making arrangements to have body pulled off this by the end of this weekend so I should be ready slighty before you are. Then the stalking of the man in brown can begin;)

Re: Dropmember Rear 63-72 Spy Pic
 

Nate- Will this ship via UPS? I think the front kits were too big to ship, correct?

Re: Dropmember Rear 63-72 Spy Pic
 

My DM front came ups although the box had a rough go. Also from talking to Nathan about the rear design it has been designed to ship UPS.

Re: Dropmember Rear 63-72 Spy Pic
 

That skinny AZ boy thinks of almost every angle. There's always @ least one customer that keeps him on his toes though ;) .

Re: Dropmember Rear 63-72 Spy Pic
 

Looks good Nate, tell your Pop's he is doing one heck of a job:lol: My wife keeps asking if anything has been done on this yet as she wants one for her 63 GMC;) Just go ahead and send me one and I will have her install it to show how user friendly it is:lol:

So Nate will this work with a 4x4 frame as well as a 2x4 fra, leaf or coil? If so you need to pick up a clean AZ 4x4 Blazer and put your products were your key board is!
Sure would make it easy for guys to get their "2wd Blazers".

Re: Dropmember Rear 63-72 Spy Pic
 

This kit will be a UPS shipped item... just like the front. As mentioned, I designed it in pieces that will meet the packaging and weight specs... who wants to pay truck freight?

Also, I have gained enough experience with UPS to understand that they do not take it easy on packages... especially the heavy ones! After dealing with torn box issues in the beginning, I have since switched to double boxing all components (two double walled boxes, with hardware and other pieces boxed inside) ... a little more spendy for me with the custom sized boxes, but I haven't had a "lost" component since.

Re: Dropmember Rear 63-72 Spy Pic
 

Kevin-

I don't think this particular piece will work on the 4WD chassis... but that's definitely in the future.

However, on the leaf sprung chassis... the rails are the same as the coil sprung trucks with one small difference, there are ridges pressed into the framerails to cradle the leaf spring perches. This chassis is actaually a leaf sprung chassis. As soon as I finalize the four-link design, I am bustin out my 65 big-window and doing a complete front and rear install... just to "verify" things ;). For some reason I think that the 65 will end up with a for sale sign as soon as the rolling chassis is Dropmember Equipped.

Careful... I weighed myself on my shipping scale today, I have actually gained a few pounds!:chevy:
