    Yes you run a risk of emptying the master cylinder, you need to keep an eye on it. It will take longer, advantage is you can do it with no extra help and no special tools.

    Regarding those 30 spoke Cragar wires you have, I'd bet that sandblasted and powder-coated black semi-gloss with rechromed caps would look great. Maybe not on your car, but don't toss them out. I'm just sayin'............

    Cheers.......R.

    Re: 1981 Brougham Project



    Got the headliner in the other day. I did it in black because it was readily available and I like the contrast. Also I didn't feel like matching the fabric color, I lost my contact that had the swatch book. I have to say though I'm a lot happier with the black then I thought I would be. I did clean up the interior for the most part, it had the fabric off the headliner so the deteriorated foam was all over everything, I just have to dye some spots in the seats, that I'll worry about much later. It's presentable. But... now the car won't start. Cranks for days, but won't start. It did momentarily but that's all I could get. I ran it very low (maybe out) on gas the other day, then this started. Dumped some fresh in and has about 1/4 tank now. I'm going out in a bit to search for fuel filters, but honestly know nothing about this TBI (?).

    Matt,

    I think you'll be happy with the TBI man. You can use a different ecm and work with a chip tuner like sinister performance. I'm running multiport EFI on my 472 that I put in my 78 fleetwood. I'm using a GM 1227730 ECM with Bosch red top 30lb injectors. The car runs great and i'm running on the original calibration chip. What's cool with the EFI and with the distributor being the 7-pin is there are no weights or springs to wear out and everything can be set on the ECM. The distributor i'm using is from an 81 cadillac so hang on to that distributor if you decide to go TBI. I'm sure TBI would be nice to and less hastle with changing manifolds. You could use the stock carb manifold from your 472 and use a GM 454 Throttlebody. I can try to find the popular ECM's used for TBI but what is great is you could probably pick one up from a junkyard for about 20 bucks. Moates.net has a lot of different adapters so you can put a reprogramable chip in it. On top of that you could use a knock sensor from a 454 so nothing detonates on the motor. Those Crager spokes look great by the way. If you got any questions about the TBI stuff I can try to find some info on them for you. There really isn't a lot to them. What I would do is run to the junk yard and find a 90-92 Brougham and pull the TBI harness from it since everything will be the right length for your motor. Then strip the harness down to only the TBI stuff and drop it in your car.

    Forgot to comment on your car not starting. Check and see if you're getting spark. If you are then move on to the fuel system. If you're getting spark check the fuel pressure with a guage. The most common problems with fuel injected cars is either the fuel pump is shot, or the regulator is bad and leaking so it never allows the fuel pressure to build up enough for the tbi. It couldnt hurt changing the filter either.

    I came out to mess with it and the car started right up no problems. I'm hoping this was just a fluke from it running out of gas. I'm going to let it be for now and see if it happens again. I was considering keeping the tbi in the car, but again I'm lost when it comes to that. If I can use the edelbrock manifold I have, that would be ideal. Other than ease of starting and stuff, will I benefit in performance?

    Re: 1981 Brougham Project

    So the original motor in the 81 was fuel injected? If so, I think it will need an oil pressure sensor to tell the ECM that theres enough oil pressure to start the car. The same thing happened to me, it ran for a day, then it would only start for a second or two and then cutoff. There should be a fuel pump test wire by the drivers side close to the firewall. Mine was either blue, green or orange, I'll have to look. I have that hooked up to an ignition terminal at the fuse box.

    Re: 1981 Brougham Project

    On most cars the oil pressure switch is just a backup if your fuel pump relay goes bad. If that's the case check your fuel pump relay and make sure its not bad. To be honest it's really not that bad. A lot of people are intimidated at first but it really isn't too bad. If you have a diagram it helps to get better understanding of things. There are even some places that will make harnesses and label everything so it's even easier to hook up.

    Re: 1981 Brougham Project

    Usually you will get better performance because everything can be programmed for optimal timing curve and injector pulse. You'll also get better gas mileage since it's vaporizing the fuel. Quadrajets are still pretty efficient carbs though. You can even run a throttlebody on your edelbrock manifold. If you do carb I would just keep all the wiring in a loop incase you change your mind down the road. You may even be able to use all of your stock wiring, just use a 454 throtlebody with it since the injectors are bigger. The ECM will use the timing curve for the 368 which should be a lot similar to the 472.

    Re: 1981 Brougham Project

    I'm going to the junk yard anyway on monday. So I need wiring harnesses from a 90's fwb and a 454 throttle body to start. What do I look for, just a large GMC of the late 80's early 90's? One without all the sensors? I looked a little on ebay to get an idea of what they look like. Even if I don't get the ideal one now, I'd like to get one to get the car running and I can upgrade later. The car's been starting all day so hopefully it was vapor or something. There had to be air in the lines, I replaced a large section of them. I don't know, just wishful thinking.
