    Re: Cadillac 500: It Begins.

    Got to the bottom of it.

    THIS is a 425 with a Smog Pump. Not sure exactly what was different about the water pump layout, but my water pump prevents me from using this particularly ridiculous setup. Also, if you were wondering what colours/textures my bracket was yesterday morning, they were about the same as that upper alternator arm or the pulley on the smog pump.

    (Figured I would add it in case someone else stumbles across this thread someday)

    While I believe that the top arm will work no matter what, I will have to acquire the bottom piece. I look forward to having an alternator that mounts in a sensible way, unlike the design on the 307...

    Re: Cadillac 500: It Begins.

    Took a couple days from when I started it, but only because I was at work and could not continue forward, as I was waiting for parts, but here it is. The Quadrajet. While in there replacing gaskets, I replaced some bots and such and repaired some others. I also added a brass float and I converted the choke switch to an electric one, but that is not mounted here. I will have to find some means to mount that to the carb when I put it on the intake, as the Edelbrock intake does not have mounts for the choke switch, so I figure I can make a sheet metal bracket that extends from between the carb base and the rear mounting bolt, because it is accessible and open.



    Didn't go crazy on the rusty pieces, though there are sources to get new ones, but they all work fine, so I didn't bother.

    Yea, I'm interested in how the Q-jet works also.

    Re: Cadillac 500: It Begins.

    From what I am told, the Olds 455 Qjet is supposed to be a beast. Considering it was a bunch of hype and I got this thing taken apart and put back together with new parts in a snap (Thanks for the information, Cadforce. I am sure I will still need to tune it when I install it) I may just go ahead and grab a 455's carb someday and do it all over again.

    Re: Cadillac 500: It Begins.



    Well, though it looks like I will have to drill out and retap one of the bell-housing mounts for the transmission, at least it is starting to look like an engine.

    This engine stand is absolutely massive and very stable, but I am wondering if I should let it sit without the actual engine hoist connected to it. It is not the stand I do not trust but the bolts/spacers that are connected to the engine. If the photo does not load, my apologies. Photobucket is being very finicky about this particular snapshot for some reason.

    Re: Cadillac 500: It Begins.

    It looks awesome! I think I would use both stand and hoist. With such a heavy and powerful beast all security is not enough.

    Good luck with the bell-housing mount hole!

    Re: Cadillac 500: It Begins.

    Wow, why is that stand so big? Is it for truck or airplane engines? Engine looks mean. How about getting some brushed aluminum vinyl "Cadillac" scripts cut for the tops of the valve covers?

    Re: Cadillac 500: It Begins.

    It's such a big stand, because it's for 6BT Cummins Diesels. Got it through work connections. Guess if I ever have to pull my 16.4 Litre truck engine (Yes, my big work truck is nearly two 500's) I'd love to get the valve covers labeled, but not with stickers. I'd need to have them engraved. Too bad I got them this way, because I could have just ordered the same ones pre-cut with breather holes, baffles and Caddy script if I didn't already have a set.



    The other cool thing about this stand is that all it needs are front supports and I can definitely run an engine on it. I probably could now, but would prefer not to risk it.

    Speaking of supports, I can use the factory mounting brackets from any 500-472-425-powered RWD car or no? Also, does anyone know where to get some good Headers for this monster? I have an awesome set, but they will never work in a Brougham. They'd be great for airboat/ratrod application. Big, mean and definitely loud.

    Re: Cadillac 500: It Begins.

    I knew that stand was for a truck. If it can hold a Cummins, it will take that Caddy like it is nothing. Remember, a 500 weighs only a little more that a Chevy small block.

    engine side mounts have to come from 77 and up 425/368 cars.

    Like I said, it is less the stand I distrust, more the hardware from Lowe's. So far so good though.

    Thanks, Csbuckn. I figured as much on the mounts. Was not sure if a RWD 500 platform would have the right mounts. Good to know though. Now if only I had some 368 cars at the junkyards...

    Checked their inventory, because I will have to go for my fan unit soon anyhow. Lots of oddball 70's cars like MG's and Datsuns in there this month and two big early seventies Rivieras. Not relevant to my build, but interesting, since it usually just had eighties cars at the oldest and never anything too out-of-the-ordinary.

    Re: Cadillac 500: It Begins.

    Alright then, thanks to my newest batch of supplies arriving today, it is intake time (Also, more Silly Hats)

    Okay then, so what is the proper bolt-down pattern for this engine?

    Also, and this is a bit more technical, I have seen varying degrees of how to best install this intake. I already know I should use sealer, because though many sources say no sealer is needed for the intake gaskets, most people who have actually done it, say YES, use the sealer. However, what about the Valley Pan? I have even heard people say they do not use it (I figure I should)

    Do I put a layer of sealer between all surfaces? Therefore, engine, sealer, gasket, sealer, valley pan, sealer, then bolt down the intake?

    Re: Cadillac 500: It Begins.

    I put sealer between both sides of my fiber gaskets. You could call Marty @MTS and see what he says. I installed dry and they leaked, I ended up machining .015" off and reinstalling per Marty and others over at another forum. Hopefully they arent leaking.
