    parts are starting to get here. i'm going to slowly attempt to make my truck look fresh again. clean thread, from scratch documenting the process. thanks to everyone who has given advice up to this point and thanks for the help that is yet to come.

    the engine is new from GM via summit. if you look at the review score it's 4.5 stars. 33 reviews total, 2 bad. here are the bad ones:

    should I pull the pan and check the torque on the mains and CRs? will this void the warranty? I thought gm would be building these with those crazy machines that torque all the bolts on a particular component down at the same time. I realize of the thousands, if not more, of these particular engines sold only 33 people decided to leave a review. I figure that if anyone had as bad an experience as the previously mentioned reviewers did, a good portion of them would have left a review. so maybe it's super uncommon to get a zero mile engine from GM that has poorly torqued parts? I'm leaning towards just building it up and leaving it be but I thought id ask so the more experienced engine guys could chime in with their opinions.

    carved out a little space in my garage. my wife doesn't know it yet, but I might have to pick up a carport from Costco if my new garage takes any longer.

    I've installed a handful of new GM crate motors. Every last one of them was quiet and had the rod bolts torqued. Does that improve your odds?

    haven't hit the junk yard for a radiator fan yet. I wanted to check my dimensions against some of your guy's radiator/shroud. radiator is 41.5" wide overall and shroud inner diameter is 22". is that the size on everyones truck? is it a diesel radiator?

    I'll be keeping my eyes peeled for the tbird or other ford fans mentioned in the numerous e-fan threads, unless those are for a smaller shroud. I'd like the fan to fit into the shroud without any brackets and I don't want to have to measure every vehicle there if I don't have to. thanks.

    I'm holding off on unwrapping the motor I get everything. I'm sawing a lot of wood around here and don't dust in everything.

    I'll be pulling the seats and carpet tomorrow. hopefully I don't find any surprises. I hit the floor everywhere with a hammer, sounds good I think. I'm going to try to put my existing carpet kit in my washing machine when my wife isn't looking. anyone tried this before?

    anything you guys would recommend over por-13 for coating floor. that's what I used to use on vw/porshce pans back in the day. It seemed durable enough but dried kinda hard. seems like something more flexible would last longer.

    I wouldn’t do that to the carpet, unless you really want to buy a new one. I used Tide ( not Pods) a scrub brush and a weak pressure washer to good results and mine is tan.

    I also had it laying on my concrete patio. Not sure if it mattered but it gives you something solid to scrub on and won’t wick crud back up threw, While it sun dries.

    That's a vacuum source. EGR looks like this. GM 12496820 - Low-rise Vortec intake w/EGR.

    okay, thanks! so I could put a manifold vacuum sending unit in there to run a gauge in my truck?

    so I'm kind of evaluating everything today as to what needs to happen in the spring preservation-wise. I'm getting super excited. I've pulled back the carpets and it looks incredible. most of the old vw/porsche stuff I've done have been flintstone cars when I get them. wiping the frame down in the engine bay, it looks brand new. its just dirty from ranch duty.

    I have a question about a part:

    IMG_0281.JPG

    IMG_0282.JPG


    it goes here on the frame in the two holes where I wiped clean, I had to remove it to fit the long tube headers that I used to have. I kept it around in the garage. I think it is unique to cucv frames but I'm not sure:

    IMG_0280.JPG

    when it's bolted in, it pitches back about 20 degrees and must act as a bump stop for the d60 pumpkin. it would be at this angle installed:

    IMG_0284.JPG


    obviously it acts like a gusset as well, so it strengthens that part of the frame. i think it'll clear my new mid length stainless headers. anyone else have this part?

    something peculiar about the radiator too. gotta love the triple hose clamp job that the PO pulled off. I think it's a 6.2 radiator:

    IMG_0285 2.jpg

    it has bungs on both sides. the tranny is piped into the driver side but also has a secondary cooler in front of the radiator:

    IMG_0287.JPG

    IMG_0289.JPG

    nice and straight, I know...

    on the passenger side of the radiator it has two more large bungs with nothing in them, not even a plug:

    IMG_0288.JPG

    they are big. I can put my finger in them. is this an open provision for cooling something else? they have clean threads. maybe for cooling engine oil?

    That bump bracket is an odd one. I had read in the past it was used on trucks with the quad shock option. Your frame seems to disprove that.

    My K30 doesn't have that bracket. With regards to the passenger side tank, it could be for engine oil cooling, but I've never had a 6.2. Here's what my big block radiator looks like. The second photo is the engine oil cooler set up. IMG_1338.JPG IMG_1337.JPG

    so you've left the passenger side bungs open too?
