Re: Knomadd '71 SWB C-10
So I got it figured out. The sleeve in the center of the core support bushing was too tall, so I cut it down, and I took about 1/8" off the rubber bushing. It's extremely close, so I let it go and started assembling the front end. To get it perfect, I'd probably need to take off another 1/16-1/8". Here's the sleeve I was referring too:

Re: Knomadd '71 SWB C-10
Way tall! Wonder what application it's for?

Re: Knomadd '71 SWB C-10
Still working on this thing... it's kicking my butt though. Work has been getting in the way, which makes things more difficult, but I think I'm getting close to firing it. I still have some wiring for the fans and A/C (waiting on electrical terminals to custom route my wires), fluids to fill, steam port line to connect to radiator, eLevel ride height sensors to install and connect, and front end to assemble... soon, if I can get the time and motivation (or at least stop being lazy when I get home from work) to get it done.

Re: Knomadd '71 SWB C-10
Your truck is looking so nice! I've had the same issue with that bushing before under the support. What a pita that can be to finally find. Haha

Re: Knomadd '71 SWB C-10
With any luck, I can get the fan wiring done tonight, or tomorrow morning and fire the engine for the first time! I'll take video and post it if I do fire it.

Re: Knomadd '71 SWB C-10
It is coming together very nicely! Looking forward to the start video.

Re: Knomadd '71 SWB C-10
Getting close!

Yah buddy! Love it! I was hoping you would get out and walk around truck while she was running.

Re: Knomadd '71 SWB C-10
Well, I got it outside for the first time in months!
http://67-72chevytrucks.com/gallery/...9_17_30_20.jpg It's up on the jack so I could bleed the power steering / hydroboost system. That didn't go so well... I'm still not done with it. I've done this twice before with an empty (new) hydroboost system and haven't had this much trouble bleeding the system. I guess I'm just being impatient. I'll get the air out, but damn! This is a PITA this time. |
Re: Knomadd '71 SWB C-10
Way to go, Duane! Cool sunvisor... ;)

Re: Knomadd '71 SWB C-10
Where did you source your intake parts? That filter is huge!
|
Re: Knomadd '71 SWB C-10
I see the Dapper headlights are in. Have you lit them up yet? How do you like them? Mine have been sitting in the box for months now.

Re: Knomadd '71 SWB C-10
Pulled Brutus outside for a bit and finally took a walk around video. :bowtie: It's nice to finally have the power steering system bled and working right. FYI, if you run hydroboost with a GM power steering pump made for a hydroboost application, make sure you put the hydroboost return on the top port and the steering return on the bottom port. If you swap it, there's too much agitation in the fluid and it causes "cavitation."
|
Re: Knomadd '71 SWB C-10
Very nice! Good advice on the hydroboost return too.
|
Re: Knomadd '71 SWB C-10
Very nice! It turned out so clean and sounds great too!
|
Re: Knomadd '71 SWB C-10
Sounds (and looks) great, Duane. I'm living vicariously thru other builds since mine is bogged down with wires running everywhere. Having an actual running truck represents a lot of work. Way to go!

I got to drive the truck to the inspection place and back home. The motor now has 63 miles on it (61 when it was installed). :lol: It sure does have some power! :chevy: The transmission shifts weirdly though. I'm not sure if I just need to add some more fluid or if I need the tuner to make adjustments. I'll be topping off the fluids this weekend and making a few adjustments (my reverse lights are on in drive, so I need to move the NSS), but I can't legally drive it until Monday. I need to go renew my registration, and they're closed today in observance of Veterans Day. Once I have my renewed registration, I'll be data logging with HP Tuners and sending my tune back to the tuner for adjusting. I'm hoping I can learn from what he's done to the file from stock to now, and again after he makes some changes. |

You had asked me about an adapter for a card MAF and said you could weld stainless. MA Performance makes one but I'm not sure if this is the kind you'd need?

So I got it running, inspected and registered, so I took it to a local show in a nearby town for its first outing...

Re: Knomadd '71 SWB C-10
Awesome! That has to be a good feeling. I'm jealous you have weather nice enough to still do fun stuff. :lol:
|
Re: Knomadd '71 SWB C-10
Thanks Ryan, but I do miss snow sometimes. Especially around Christmas. But I bet your summers are nicer than mine! Sometimes I think I need to take summers off while you'll be enjoying nicer weather.
|
Re: Knomadd '71 SWB C-10
I think you'd get a surprise if you come here in June through September. My Uncle from Brazoria always rants about how we have it so easy with no heat and humidity. That's why every time he's up here, his azz is in the house in the ac most of the time. :lol:

Re: Knomadd '71 SWB C-10
Truck looks awesome Duane, congrats on being able to drive and enjoy that new LS motor.

Re: Knomadd '71 SWB C-10
Awesome Job!!! That engine sounds great!!!

Re: Knomadd '71 SWB C-10
Congrats Duane! All that hard work finally paying off. Great job on the whole project :metal:

Update: I've been dealing with an ultra high fuel trim (30 to 34 long term with 16-28 short term) which says I have a really lean condition. For those who don't know (like I didn't) the fuel trims should be close to 0, but never more than about +/- 10. Negative is rich, positive is lean. Research says I have either unmetered air (vacuum leak) or lack of fuel (low pressure). I've removed and reinstalled the intake, added a fuel pressure sensor from Dakota Digital (61.7 psi at idle), and replaced the MAF sensor in case it was dirty and giving a bad reading. None of these things changed the trims. I'm contacting my tuner to see if he made an adjustment for the cold air intake since it's a 3.5" tube. I don't know what the van would have had, but I bet it wasn't that large. I'm also trying to borrow a smoke tester to check for leaks, but I'm waiting for now. If anyone has any ideas I should try, I'm all ears (or eyes since I'll be reading them). |
Re: Knomadd '71 SWB C-10
Sounds like you’re on the right track. My first instincts say vacuum leak or MAF issue, which is what you’re focused on. Keep us posted
|
Re: Knomadd '71 SWB C-10
We got the tune figured out finally! It was the MAF sensor tables in the tune. It was reading too much air for the system, thinking it was lean. Once that was adjusted (about 4 times) everything is now in the -7 to -3 range, slightly rich, but good for a performance type tune.
It's been a couple weeks since that was fixed, but I caught a nasty cold that hung around for a while. I was finally able to drive it to work today http://67-72chevytrucks.com/gallery/...0_08_33_44.jpg http://67-72chevytrucks.com/gallery/...0_08_34_03.jpg http://67-72chevytrucks.com/gallery/...0_15_15_16.jpg It runs like a scalded dog! I took it for a quick run after lunch and at about 3/4 throttle it accelerated HARD! Man this thing's going to be fun! :chevy: |
Re: Knomadd '71 SWB C-10
Oh yeah, and I ordered wheels during Black Friday sales and just got confirmation that they will be here the day after Christmas. Now I just need to find the tires I want. I'll be out of state, visiting family in Oregon from Christmas through New Years, so it'll have to wait until then.
Here are the new wheels: http://introwheels.com/wp-content/up...xlr_retro1.png |
