Re: Palf's 1981 GMC
Got tied up with other things, but there does not appear to be water/coolant in the oil, but coolant was about a gallon low. I can't see any external leaks. I will pull plugs in the morning to see if I can see which cylinder(s) might have water and check compression.. Since this integrated head is know to have issues, I am hoping that is the issue and I'll just do my conversion to early style head sooner.
My pocket book definitely does not have funds for that stuff Steven & Jeremy. I like my little in-liner and want to stay with it, but I do know where there is a good running 350.

Re: Palf's 1981 GMC
Well got at it early this morning. Started pulling the plugs. #6 was first and it looked damp. The other 5 looked very clean and normal. So I hooked up the remote starter and cranked the engine. Soon as I did # 6 was spitting out small amounts of water/stuff. All others were clean. So tore down things to get the head off. A 6 popper head is HEAVY to lift out of the engine bay yourself, just sayin.🤓
The rear 2 head bolts didn't feel as snug as the rest, but with the head off the engine itself looks clean to me (well way cleaner than the outside). No water was in the cylinder other than a drop or two. Again head looks clean except for #6. Ran a strait edge and it seems to be straight. The head gasket was a bit deteriorated around # 6, so I am assuming that is the issue. I noticed some issues with the exhaust manifold, beside breaking off some bolts in it. Rest of the engine looks good, so right now my plan is to keep the 6 and do the head swap to the older style non-integrated head. I have a 4bbl Offenhauser intake and a Holley carb, but will need to get some headers. I will have to see what other brackets I will need for the head swap. Since it will take a while to gather funds and parts, I think I will pull the block and regasket everything and clean the engine bay up while I am waiting. Looks like no driving for a while. ![]()

Re: Palf's 1981 GMC
I'll send you some pics of what I have when I get home this weekend so you can decide if you want to drive to my house or not.

Re: Palf's 1981 GMC
Whamo, Thank you.
As far as the truck, no real work forward yet. Weather has been cold, low 40s for us is way cold. ![]()

Re: Palf's 1981 GMC
Today I drove over to a friends that is over past Lafayette, Louisiana (about 220 miles). Steven (smbrouss70) offered me 2 250 six engines he has for parts. Since our weather has left both of our yards pretty soggy (it will take 6 months of no rain before anything big can go into the yard without sinking), decided just to grab the top ends for now. In a tight old shed, it worked my old muscles for sure getting them off. 50+ year GM torqued head bolts do not come out very easily. They are also heavy with both manifolds on, even with the 2 of us toting them. Dang I am getting old! Couple hours to get them out and loaded, then grabbed some food, then the 3.5 hr drive home. I was too tired and lazy to unload them when I got back, but I now have 3 old style heads now, so hopefully one of them will be good enough to redo and add to the 81 lower end.
Going to talk with the friend/machinist that builds race engines and see what he needs and what level I am going to go with it. Slowly, but I am making some steps (although they are sore at the moment ![]() Oh, the 3rd picture was his suggestion as a suitable sub for the 250 ![]()

Re: Palf's 1981 GMC
I'm just glad that they are finally going to be of some use to somebody. Those engines have been sitting in that shed for about 15 years now... as you could tell by the nests surrounding those engines!

Re: Palf's 1981 GMC
Blown big blocks = instant torque!!!!
You might have to window the hood for clearance issues, however...

Re: Palf's 1981 GMC
What do you have in mind for power steering pump and AC compressor brackets with the older style heads?

Re: Palf's 1981 GMC
Near as I can figure so far, the old head has the mounting holes for my AC bracket like the newer style head (small pancake compressor (or whatever they are called). Power steering I am still looking at. I might be able to mod the bracket I have to work. If not I'll find one that will work.
I have also been looking at these folks as they have all kinds of brackets that should work. https://davisspeedequipment.com/prod...tegrated-head/

Re: Palf's 1981 GMC
That blown big-block is a beast. True injection on top. A far and away dream for me would be to have a relatively stock-looking, long bed C20 with a motor like that stuffed under the hood. The manifold under the blower looks particularly tall and if that was replaced, maybe it would fit under the hood. Spin the injection 180 degrees and open up the cowl for airflow... I would even make frame alterations and exhaust compromises to get that to sit under a stock hood, haha. Probably would have people telling me I needed to tighten my fan belt as I idled by with my secret blower whine. Now back to my 305, already in progress, and your six-in-a-row. Good luck with the work ahead!

Re: Palf's 1981 GMC
I agree LT7a, my wife is one of the main folks for it from our church for the last 10ish years. My part is helping with deliveries, especially if there is a bike (almost every year she and I get some kid one.)
That big block was at my friends shop and yes that is a FAR FAR AWAY dream, but would be cool if I ever won the lottery (which won't happen since I don't buy tickets). Slowly getting my cash together so I can get the work done. on the 6popper.

Re: Palf's 1981 GMC
Good and some bad this weekend. Got the lower half of engine out on Friday evening. Plan on taking the stuff I have, the 81 block, couple old style heads, the 4bbl intake and other stuff to builder this week. Get that old 6 banger going again.
The bad, my DD driver, the 06 died. I was getting ready to drive 4.5 hrs to central Louisiana to get parts for my truck and a friends car. Parked the truck Friday afternoon, Saturday morning, jumped into go, turned the key, it started to fire, then bang and dead. Spent all day I am guessing fuel pump dies but so far it is giving me intermittent indications that it is and is not pump. Stopped after a while yesterday before I got to ticked and smashed it. I'll dive into that again tomorrow morning. Oh the fun of old and oldish trucks. Good thing is it died at home and not several hundred miles away.

She looks so sad, hopefully she will smile again when the new guts are put back in.

Sorry to hear about the DD. Intermittent problems are never fun to track down!

Re: Palf's 1981 GMC
Last bit of parts arrived for the engine redo. Edelbrock 500 and the headers. I also completed throttle cables mount.
The original cables ran thru a mount that was attached to the valve cover on the integrated head. I drilled out the spot welds and removed it from the origainl valve cover. I then cut the piece off where it mounts to the valve cover bolts and created a new on out of some scrap steel.

Re: Palf's 1981 GMC
Made a new mounting piece and welded it to the original mount. It will now be held down similar to the original using the valve cover bolts. Cleaned up the welds and primed/painted it. I also put a small piece of heat resistant HD rubber under it so that it is not rubbing metal on metal with the old head style valve cover. I think it should hold up and since that was the original way they ran I figured I would not need new cables or fancy (expensive) cable mounts. We will see when it comes back with the engine.

Re: Palf's 1981 GMC
Still waiting on the engine to get done. Been down and out of the weather for a while, but starting to get back into workings again. Wife and I took a trip up north Mississippi to vist the Tupelo Auto Museum before it closes its doors forever. It is a shame, but things like this just don't seem to have the draw as much as they used to.. The collect is great and a whole group of wonderful cars from the 1890's till later.
The Tucker was the real treat. I have seen 2 others in my life, in restored and one that was still driven as a rusty/banged up hulk. Link has the pictures I took while there.
