Nice job man. I can't believe your hood shuts with that air cleaner, I just put the same intake on with the aluminum heads and I got shit for clearance. Do you have the part # for the upper rad hose?

Great job. Car is sweet. Hope to have mine lookin that sleeper. Don't know if I'll be able to control the noise either :lol: . That 455 looks sweet though.

Lookin' good there Mike! That's motivation for me to finish my turd. Out of curiosity, have you done anything with the front springs at all?

Thanks guys, I really appreciate all the compliments. Mostly what you see is how I got it. Other than cleaning up the engine and stuffing it in there, I haven't done much else. It still has the 2.41 gears, so right now it really shines on the highway. I have an 8.5 3.42 posi picked out that's going in first thing when it warms up.

On the hood clearance, I can only guess it's got something to do with body or motor mounts, or just the dropdown of the air cleaner itself. It's closer than close, it's actually touching the insulation, but it still makes it. I'm planning to put something a little less flashy if I can find a factory air cleaner that has enough of a drop. On the upper hose, I believe I just asked for a an upper from a 1975 455 Cutlass, don't know the part number. I keep a list, and it's kind of funny with a car like this. When I have to go to the counter for parts, they ask what kind of car it's for, and I have to tell them '75 Cutlass for this, '83 Cutlass for that, '70 Olds 98 for the other thing... I keep my specs in the glove compartment, just in case I ever get hit by a train and someone else has to maintain the car. :D

On the springs, those are the factory V6 springs. The only suspension part I changed was the shocks, I went with Monroe Sensatracks. Those gave it a slight lift, but the factory shocks, which is what was still on there, were completely shot. I like the stance, but the spring rate might not be high enough on the fronts. Once I get new tires, I'll see what I think. If I did anything, I'd go with the mildest step up that would allow me to keep the same stance. The stock front springs as far as I can tell are 5598s, and I believe the MCSS springs are 5606s. I've seen these, and they tend to raise the front a bit. If they are the next step, I'd probably use those and cut off an inch. Still have to do my research here. I'd be interested in hearing your ideas or suggestions on this.

Here's the trusty spring list if it helps
http://jeffd.50megs.com/Moog_Spring_Page.htm

I got a set of new 5664's for $40 some time ago and I'm going to give those a shot. Probably overkill, but we'll see. I had an '80 Regal with a Poncho 400 & V6 springs and the front end was slammed after the swap. The fender lip was just barely above the bead of the wheel :shock:

G-body, thank you for the link. That actually helped a whole lot. I was able to create a spreadsheet using the calculations he lays out there, and from that I was able to come up with good final ride height estimates based on my weight. If you'd like me to plug in any numbers for your combo, let me know.

So I have a couple questions. Currently my car is on stock 92k mile AC V6 springs all around. The weight is pretty near stock, maybe even a little lighter with the weight reduction I've done. The car came from the factory with a front sway bar, and I've since installed a factory rear sway bar as well. Also installed Monroe Sensatracks, which I like. My ultimate goal is to keep the front at right about the height it's at now, get the rear just a little bit lower to match, and firm up the springs all around. It seems the right springs for me to use would be Moog 5658 fronts and 5413 rears. My first question is, does this sound right for my goals? Second, I'd like to do as much of the work as possible on the rear when I install the 8.5, including installing the rear springs and boxing the lower control arms. Will it create problems if I install the new rear springs now and wait to install the new front springs until later when I do a more complete front end rebuild? A future front end rebuild would include springs, new control arm bushings, ball joints, a larger sway bar with poly end-links and bushings, and possibly a brake upgrade. Any advice is appreciated. This picture shows my current ride height, with a full tank of gas.

Im running the Moog 5660 which are the s-10 v6 springs. All new bushings in the control arms. A 36MM WS-6 Pont T/A Sway Bar, Energy Suspension links, an entire UMI suspension upgrade for the upper and lower control arms, New Energy Suspension bushings in the differential housing, regular rate coils for the rear and a rear sway bar. I too have a sleeper like you it just rumbles a bit at the stop light and handles like a dream. I dont think you could run into any issues changing out any springs. Now if you start swapping rear control arms you will want the alignment checked.

If I were you I would get tubular front control arms. I wish I would have done it.

Thanks Toby, nice car! That picture of your car in your album, is that with the 5660s and full weight? Your stance looks almost exactly like mine is now, which is how I'd like to keep it. I'll almost certainly go with the 5658s or the 5660s. Most of your other suggestions are on my to-do list. Tubular front arms aren't really, but maybe I'll look into them. Wow, I just noticed, you've got whitewalls even. :) If I could get 3/4" 215-65-15 whitewalls that were made here by an American company for around $100 each, I'd run them forever.

Jam, now you've got me wondering, what the heck did those middle primaries look like? At any rate, yes, I've got regular old iron heads with the siamesed center ports, I just threw the headers on. I want to say the gasket seals all the way around the combined area of both ports, and the primaries come up just like if there was a divider. Makes me wonder if there's a gasket that works with the divider if you have one built in? Anyway, I've got the Hooker 3203s and I'm extremely happy with them and had no problems with them.
