I have a side picture which is about 2-3 yrs old now, but the car looks the same. It has Cooper 235/ 60x15 tires which I see that you plan on using. I hope this helps you somewhat.

Thanks man! That is basically the tire-fender lip clearance I'm looking for with that size tire and wheel. Nice looking wagon, I dig the body color steel wheels and poverty hubcaps. I think mine may be a teeny bit higher in the front end being as it's 150lbs lighter than an all iron SBC. If it ends up that way, I can either cut them or jack my air shocks up to get it level. I think the 5606 springs will be a fine fit. I guess we'll all know come spring.I have a side picture which is about 2-3 yrs old now, but the car looks the same.

Mr. Sony,
I'm going to call BS that an Iron Head, Iron Manifold Buick 350 only weighs 450lbs. AL manifold, AL Heads, No Starter, no accessories, no oil, no coolant, maybe, but not stock and running.
The puny All aluminum Buick 215 V8 weighs 405 lbs, and its a LOT smaller than a Buick 350.
A Turbo Regal motor weighs 420 and has Tubular headers and Aluminum intake manifold and the turbo weighs about 12 lbs. Subtract 12lbs, Multiply by 1.20 (to roughly turn a V6 into a V8) = 490 then add Iron manifolds +25 = 515 and that is probably being generous.
450lbs would be lighter than an All AL LS1 which is physically smaller than a Buick 350. Buick 350's may be light, but they are not THAT light, regardless of what T/A performance says. They can't change the density of cast iron to make it less than Aluminum. 450lbs with AL heads, AL manifolds, Headers, no accessories, lightweight starter and no fluids, maybe.
Until some shows me a scale with a 450lb ready to run Iron head, Iron manifold motor with accessories Buick 350 on it, call me a non believer.

OK, I found the Buick 350 weight breakdown on the Internets:
Shortblock: 273 lbs
Heads: 57 lbs each
4bbl Intake manifold: 60 lbs
That's 447 lbs just there.
starter: 16 lbs
alternator: 8 lbs
Power steering pump/brackets: 10 lbs
Harmonic balancer, distributor, valve covers, pushrods, carb, fuel pump, etc: 40lbs
That's 521 lbs
Add 23lbs of Iron exhaust manifolds:
544 lbs.
With no fluids and no A/C.
Light, but not THAT light.

I've always heard that the Buick 350 was a lighter engine compared to a Chevy 350. Despite some aluminum parts on the Buick engine, the stock iron intakes on those weigh a ton.
The aluminum Buick 350 Poston manifold I had was considerably heavier than a typical SBC Edelbrock Performer intake.

Hey, thanks man, I appreciate it. The springs in my car are probably 25-26 yrs old, believe it or not...so they're quite settled in. They were slightly higher when I first installed them, plus I was running a taller tire at the time...wonderful NYC streets with scores of potholes. I needed the extra clearance. My has a small block Chevy with A/C, if that makes much of a difference regarding weight differential.
I still think the 5658's might be a better option. I would urge you to check out the spring chart and make a comparison between these springs...spring height, spring rate, etc.
I guess now I have a theory to test. I've ALWAYS heard the 350 Buick was over 100lbs lighter than a SBC, iron vs iron due to the Buick having more nickle in the metal, therefore making the whole block stronger and leading to less material being needed in the construction of the block. When I looked at them side by side, a Chevy 350 block is a LOT thicker and bulkier in the bottom end.
It is a very light engine. I firmly believe that it is under 500lbs at least. Hell, even HorsePower TV touted the 450lb claim. When I got my block back from the machine shop, I was able to lift it out of the car and walked it to the garage 10 feet away. It took me and my dad to pick up his olds, and struggled with two people to shuffle my brother's SBC from place to place. The intake I will admit, is unnecessarily girthy. I mean, 67 lbs. What the hell is in that thing? Every source I've found states the engine about 450-470lbs. When I take my engine back out this spring, I suppose I'll weigh everything to see. I'm taking it apart anyway to inspect my handywork so I guess we'll see. I don't really know of any bathroom scale that supports upto 500lbs, nor do I have 500$ to shell out for an engine scale that attaches to a hoist.
I think one of the only people that would be able to put up actual real world results would be joesregalproject since he has a 350 buick like mine.
