    I know, the 472's been in another '81 already, the body just got too far gone. I tossed the computer in that one. The nice thing about this swap is that I saved all the wiring. It should just "plug in" for the most part. That's why I'm almost embarrassed to pay someone to do it, but with the baby crawling now and my other son running around like a nut, the few hours I get at home are quickly consumed.

    Re: 1981 Brougham Project

    I got the call today that the headers fit, so I took them home to have them coated, or paint them myself. The tranny's in and the engine bay's been washed and painted (roughly). I don't really know what to do now. My neighbor and I are rebuilding the carb and I'm thinking about having the shop fit the exhaust and send the car home for the rest. I was going to have them do the whole job, but I'm having second thoughts. I've been doing a "pay as you go" kind of deal, and the headers weren't in the original plan, now there's a ripple in the billing. It's totally my fault, but to save the headache and money I think I may be finishing this alone. Whatever, nothing I haven't done. I'll get more pics soon.

    Re: 1981 Brougham Project

    Hello!
    I have the same year 4 door version. Read all the thread and found many useful info.
    My ride came without a TBI and some carburetor was installed. Now I want to return TBI back.
    You were going to install 454 Tbi. Any success? There are some on ebay, but nobody knows will they fit or not.
    If you already installed it have got any boost?
    THank you!

    I've decided to go with a quadrajet. I don't have much luck with technology so I'm going primitive and simple. Most of my issues have been computer or electrical and I'm just tired of it.

    You mean you are going to switch to the carburetor system and get rid of Throttle body and ECM?

    Yes, that's how this engine was set up in the coupe. I'm done troubleshooting electrical crap, I don't have it in me to deal with it.

    This is all I've got for pics at this point. I got the driveshaft in today, as well as the headers, tranny cooler lines and some loose bolts here and there. I'll get more to it this weekend. I'd like to get under the car done so I can put it on the ground. I've got the wiring harnesses in my basement and I'm going to strip the loom off and start fresh. I'd like to clip all the stuff I'm not using. Simple and clean is how I want this.

    And for the manifold gaskets, is the silver supposed to be against the head or the header?

    Got a lot farther today than I expected. Ran new fuel lines, got most of the cooling system in, wired all the necessary electrical, and got the starter in. Also threw on one of those fancy deep aluminum tranny pans. I'm going to do plugs and wires this week, other than that, fluids should be it. I cranked it just to hear the starter and it's looking good. Can't wait to hear the open headers.

    And for whatever reason the hood actually closes!

    That is a thing of beauty, seeing that big, proper Cadillac heart about to beat in a gorgeous 81!
    ...and the hood closing is nice, could always just run without if need be....

    I started it up today. Didn't get to any tuning or adjustments, but I got all the header panel wires soldered. Almost choked to death on the smoke from the eastwood header paint, but that seems to be done with. I need to find a harder throttle return spring, but other than that it seems OK. I don't see any leaks so far. I'll get some good pics this weekend and some closeups of some stuff I did.

    Here's a shot of the new fuel line I ran. I'm in love with the copper blend whatever it's called plumbing they got out now, just not the cost. I did new fuel line from the filter near the rear wheel through the fuel pump and up to the carb. I found a very slightly used set of Delco plugs in the shed, old school stamped made in USA and gapped them at .45 after some research. I took it out on the road today and noticed a hard start when hot issue that brought back old memories. The timing is only about 2 degrees advanced, I'll be looking more into that tomorrow. After a small adjustment of the air/fuel needles it ran fairly well. I've got an appointment at the exhaust shop tomorrow, so we'll see if I can make the 45 minute trip without getting stopped for noise.

    Looking good. You're running straight headers to the exhaust shop?

    Yeah, wasn't as good of an idea as I originally thought. My head felt like it was in a vise for about an hour after the trip, but here's the story. I made it up there fine, job went great. I bought some new mufflers that I don't even know the make, just happy to ditch the flowmasters. I'm riding home and I got a pop or two at the carb, keep in mind I haven't really messed with it and it's been on a shelf for 2+ years. I pulled over and turned the needles in a half turn, then pulled out and it stalled at about 30 mph. Hot start issues start, dead battery symptoms, ended up getting a tow home, fires right up as soon as it's off the tow truck of course. Now it has a very loud valve tap. How did that happen just from stalling and cranking? The oil level's good.

    Hopefully this link works, I never did this through my phone before.

    Probably just a sticky lifter. A lot of time they go away on the first decent drive. Love the H pipe.

    I'm hoping it's just a sticky lifter, I was planning on dumping some tranny fluid down the carb to see if that fixes it. Neighbors are always smoking us out with the burn barrel anyway, this'll get them.
