'70 GMC SWB Money Hole

[bossmanivy]

What is the width compared to a 67-70, or a 71-72. I'm just curious because I'm on the hunt for an axle

Just so happens I have all 3, so I measured. '67-'70 is 55 1/2", '71-'72 is 57 1/2", & '73-'87 (but also includes up to '91 suburban squares) is 57 3/4".

I guess that rallies fit fine, but aftermarket wheels need more back spacing?

My aftermarket wheels fit fine. I actually bought the 1st GEN 338's when they first came out to go on my, then current, '87 SWB but they didn't fit on the front due to the rotor hub size. So they sat in my basement until I built the '76 Blazer. When I got ahold of this truck I didn't even realize that there were 2 different width rearends under the '67-'72 trucks. Heck, I just took everything out from under the Blazer and slapped it under the '70 model. The rears are 18x9.5" with 5" of backspacing and they fit with room to spare... The 18" actually appears wider than the 20x10 because the 20" has 6 1/4" backspacing, which makes the lip on my 18's bigger, which I love

Cool, I love the truck! If you have it, I would appreciate seeing a pic of the tire/wheel housing clearance. No hurry, I just know square bodies are more plentiful in the wrecking yards than are trucks

Ripped out the VERY worn out stock steering column & installed a great eBay find. Tilt column (minimal electrical mods) that works flawlessly!!! Whoop whoop.

OK, now that you have brakes and steering, you can convoy with Chad and myself on the Hot Rod Power Tour! I will be driving my Blue Oval, unless we get Chad's stepper finished by June. Here's a photo (since you have a Mustang).

WOW!!!! That's SEXY!!!

Frontend is now aligned properly and the ole truck really drives great, and stops like a Mutha!!! Now I'm going to start working on getting the other frame ready for the 5.3/4L60e swap and such. Thinking I'm going to go with the Jeep Wrangler tank and '87 Blazer sending unit to facilitate the fuel pressure requirements of the new powertrain...and it seems it'll save me about $400 which I really like

[CC69Rat]

Keep all this documented, you might have to help me with my LSx swap soon.

[nlped]

Chad, fear not! I'll be taking lots of pics and double & triple checking everything on this LSX swap business. I have to get a move on too!

[Low Elco]

[Hijack on] The stock 87 pump is insufficient in pressure from everything I've read and been told. We have to use something like a Walbro 255lph (liters per hour) to have enough pressure to keep an LS happy. [Hijack off]

[Low Elco]

Also, look up the Silver Dollar thread and see what he did fuel wise.

exactly, that or my a carter p5000,my friend runs it in his 84 c10 with a z06 cammed 5.3. He said it does the trick.

Great start brother had to swing through and check it out subbed

[nlped]

I'm going to pull the trigger on the Jeep Wrangler tank and a '87 Blazer sending unit. I'll use the Delco EP376 pump, I think . I could also use a 255lph Walbro pump...I know my Mustang one will pump at 90+ PSI without a regulator...Don't ask how :O

I had to WAY shorten the sending unit. I'd actually recommend the stock Jeep pickup for a 91 efi application and change the pump. Search the Silver Dollar build, seriously. He built the exact thing you're talking about, with great success. Here's the straight dope-

Well, I finally got a few new parts purchased for this ole truck. I got a smoking deal from a fellow board member from Huntsville Al. I bought his brand new pieces with all necessary hardware and such.

I got CPP tubular trailing arms, trailing arm mount bracket, deluxe panhard bar, shock relocation kit, transmission crossmember, tubular engine stands (with LS conversion mounts), tubular upper & lower control arms (with 73-87 ball joints), bags for front & rear with related mounting brackets, 1.25" front swaybar.

I'll probably try to do some preliminary fitting on my extra SWB frame this weekend if the rain stays away. And I'll post up some pics too
