I used the factory 5.3 hoses. They will slide on with a little silicone spray. I know they are a little small, but they seem fine once attached. You will have to trim the lower one down so it doesn't kink.

Re: '67 5.3L Build Thread
 

I'll give it a try, just wanted to make sure before I forced anything. Thanks.

Re: '67 5.3L Build Thread
 

thats what i did, but mounted the cooler to my core support between it and the grille, with higher pressure lines, not sure how high, with barbed ends...THEY told me it would work

Re: '67 5.3L Build Thread
 

Thanks, I am going to try to make some adapter plates and use the 73 up motor mounts like you used.

Re: '67 5.3L Build Thread
 

Thanks for the help, I sprayed silicone on the hoses and fittings and the hoses slid right on.

Re: '67 5.3L Build Thread
 

No problem. Glad I could help.

Re: '67 5.3L Build Thread
 

Got the new master cylinder/booster installed this weekend and put in all new brake lines. The front is the 6770FLK brake line kit from CPP. I spoke with Mario at CPP at he helped me out tremendously. He is a really great guy who is building a truck himself, so he knows how difficult things can be. If anyone else is planning on doing the same as me (Grand Slam kit and 6770FLK brake line kit) make sure to ask for 1/4" brake hoses with your grand slam. You can also see the CPP steering shaft kit. It upgrades to a universal joint at the top, a new rag joint, and a slip joint on the shaft. It is very easy to install since you just cut the stainless shaft in the middle to size and slip it in.

Re: '67 5.3L Build Thread
 

I also got a new track bar from CPP and had my drive shaft shortened and balance at Inland Empire Driveline. They also put new U-joints at both ends and put in a 27 spline slip yoke to mate up to the 4L60E. I am lucky that they are so close to me (right down the street).

Re: '67 5.3L Build Thread
 

I sent my ECM back to John at Speartech and had him remove the DOD/AFM function that was giving me problems (as some may have noticed on my other thread). The motor now runs 100X better and is super smooth. All codes are gone except for a bank 1 and 2 lean code. I was wondering if someone might know if this is because my crankcase ventilation tube is on the filter side of the MAF rather than the manifold side. Does it matter?

Re: '67 5.3L Build Thread
 

I wouldn't set it up like that. Seems like you'll be getting the MAF dirty much faster pulling engine vacuum/oil residue.

Re: '67 5.3L Build Thread
 

Very good point. I think I will relocate it no matter what.

Re: '67 5.3L Build Thread
 

Looks awesome!

if you've never cleaned the throttle body (and behind the throttle plate) on one of these LSx motors after 15k-25k miles or so.... you'll find lots of black soot all over the back. There's no fuel or coolant....and not supposed to be anything but air in one of these intakes? Surprise! Its pulling oil residue from the pcv (and who knows where else).

Re: '67 5.3L Build Thread
 

Good info, thanks. Any idea what might be causing my lean codes? I am thinking about getting a steam iron and see if I can see anywhere that the intake might be leaking.

Re: '67 5.3L Build Thread
 

well I'd have to guess......but if your getting the code on both banks, then (unless you have 2 bad 02 sensors) the only way for it to run lean on both sides is the injectors aren't doing what they should be (and are being commanded to do by the PCM to do) doing....or....you have a intake leak?

Re: '67 5.3L Build Thread
 

The O2 sensors are new and the injectors were just professionally cleaned/balanced. I must have an intake leak I think. It just seems hard to find.

Re: '67 5.3L Build Thread
 

If the intake is like mine was it has a plastic gasket frame with a rubber sort of o-ring style gasket around each port. Possible one of o-rings got pinched?

Re: '67 5.3L Build Thread
 

I believe it is the same, but I have never had it off. It went out of the wrecked truck and into my truck. I didn't take it apart at all, so I have no clue what's going on in there. I may take it to a professional and have them troubleshoot it.

Re: '67 5.3L Build Thread
 

Here is how I modified my intake. I cut out about 4" of the long tube and swapped it with the MAF.

Re: '67 5.3L Build Thread
 

I also got the bed back on this weekend and drove the truck under its own power. It was very exciting, but I have a few brake line leaks I have to take care of. I haven't figured out what I want to do for the wood in the bed yet, so I left it empty for now. Looks kinda' cool for now.

Re: '67 5.3L Build Thread
 

Congrats on the test ride, truck looks great, almost a shame to put a wood bed in and cover that nice work up, but I'm sure the wood you install will look just as good as the rest of the truck.

Re: '67 5.3L Build Thread
 

what are your plans for the fuel inlet on your tank? I have the same one and am trying to decide to put a door in the wood that opens up to the filler below.....or cut the top off my tanks filler...and put a marine setup in with a flush cap in the bedwood and a short rubber hose to connect to the tank neck.

Re: '67 5.3L Build Thread
 

its nice and lite did yu fry the tires a little ,does it have the power you were exspecting

Re: '67 5.3L Build Thread
 

I am just going to put the billet door in the wood. It looks like it should work out fairly well and I can get the billet door at Auto Zone for $50 and it is keyed.

Re: '67 5.3L Build Thread
 

No, I didn't get to test the power yet. I wanted to get the brake line leak fixed before I got crazy with it. Plus, it is pretty loud with the open headers, so I may wait for exhaust to do the real test drive.:chevy:

Re: '67 5.3L Build Thread
 

I know, it looks pretty cool without a bed floor. When the cool factor wears off I think I am going to try something that I haven't seen yet. I am going to take a sheet of birch plywood (furniture grade), route out the bed strip slots, and then cover it in the bar top coating. When I install it it should look like the regular wood boards, but cost a fraction of the price. I figure it's worth a try.

Re: '67 5.3L Build Thread
 

Seeing that 5.3 in there really makes me want to get mine done................. I just wish I had a place to work on it :)
Nice build, looks great!!

Re: '67 5.3L Build Thread
 

I know what you mean.. It does look freakin awesome without the bed done. I have my 68 gmc down to the frame right now getting prepped for blasting and powder coat and when I see other rolling chassis all rebuilt I think it looks better like that than the finished product! lol. It's a shamr we cover that awesome powder coated frame with all new lines and perdy stainless gas tank up!!! I'm just going to stare at mine for weeks when I get it back from the powder coater!!! lol

Re: '67 5.3L Build Thread
 

I just read through your build. It's too bad you are looking to sell. You'll be sorry.

Re: '67 5.3L Build Thread
 

I thought I was the only one crazy enough to just sit around and stare at it for hours and hours and hours...

Re: '67 5.3L Build Thread
 

Oh yeah, I can't wait to see the rolling chassis sittin on wheels and tires, drop kit in, 5.3l sittin in front of the 4l60e, nice aluminum tank looking perdy, and everything new..... I can't wait. I'm on a limited budget so my build will take a long time but the build is the most exciting I think. The anticipation is the best. Once its all done that’s an amazing feeling too but the build part of it may be frustrating at times but when its all done and you are sitting at the car show with it looking back at the total build will be great!!!! Great build you have so far and can't wait to see more pics soon as you go further. You are building it just like I want to so its neat to see your progress.

Re: '67 5.3L Build Thread
 

:lol: yes brakes are better than a running engine ........when your driving down the road!

Re: '67 5.3L Build Thread
 

how are you going to hook up your a/c lines at the compressor? i have the same old air system coming but the denso compressor lines are different than what the old air system comes with.

Re: '67 5.3L Build Thread
 

I'm not quite sure yet. Do you have any ideas? I was thinking about going to my local "hose man" and see what he can come up with. I know I am going to have to use Docs Blocks connectors to clear the frame. I'll post it on here when I come up with something.

Re: '67 5.3L Build Thread
 

I called and talked to them and they told me to get the denso lines and send them to them and they would weld the right fittings on them. i will get it mocked up next week before i send the line too them. I pick used line up a local wrecking yard and they need to be 03 0r newer.

Re: '67 5.3L Build Thread
 

I have the OEM lines for my motor, so I am hoping I can do something with those.

Re: '67 5.3L Build Thread
 

What were problems you encountered with the DOD/AFM that made you delete them? Sweet built like I said before!

Re: '67 5.3L Build Thread
 

When they removed my motor from the silverado they broke the AFM connector in the back. Rather than repair the connector I just deleted the AFM. LS1tech also convinced me. They say that it creates a horrible sound when 4 cyl mode kicks in with anything but factory exhaust. There are also reports of oil usage (up to 1 quart a month) with it on. All that together just made me decide it wasn't worth the small mileage gains.

Re: '67 5.3L Build Thread
 

found the ac fittings we need. www.rayeveritt.com. keep me posted

Re: '67 5.3L Build Thread
 

WOW!!! That is a great site. I think you may have solved my problems. The custom hoses with the Docs Blocks at the compressor and I think I have a full system.
