    Dear V-8 Buick engine gurus, :3gears:

    Every now and then I find myself wondering about the physical weight of the various Buick engines that have been made. For example, I've been given conflicting claims about how much the Buick 350 weighs. I also would be curious to know how various different versions of the Buick 300 and 455 weigh.

    Is there a table out there on the web that you'all consider reliable for that information?

    Thanks for great tips to be found here!! :TU:

    Cheers, Edouard :beer

    Buick 215 = 315 pounds. I can walk around easily with my 215 block!
    Buick 350 = 450 pounds fully dressed or 420 with an alum intake or 430 with twin turbochargers like mine LOL. I did save about 200 grams per cylinder with my better rods and pistons though vs stock. My sheet metal intake is a bit less than the TA version. Bare engine with alum intake is just under 400 pounds with TA intake.

    Varified 350 weights as found in my upcoming book about SBB Performance engines:
    Aluminum Stage 1 weighs 16 lbs.
    Stock 350 weights:
    crank 50 pounds
    rods 12 pounds
    lifters 8 pounds
    heads 53 pounds each
    cam 7 pounds
    stk intake 53 pounds
    balancer 6 pounds
    timing cover with dist 8 pounds
    rockers and valve covers 6 pounds
    pistons 10 pounds
    block 160
    oil pan 6 pounds.

    Stock 350 w/alum. intake just under 400 lbs.<o:p></o:p>

    <o:p> </o:p>
    The final chapter has been written.
    We did it!!!
    After a long day with many trials and errors, on the seventh and final pull:
    1021 hp @ 6800
    and are you ready for this:
    808 ft. lbs. trq. @ 5750!!! JUST 355 inches with a procharger!<o:p></o:p>




    The lightweight champ for the cubic inches is the Buick 300 block with the 64 factory alum heads and intake stroked and poked to 349 cubes. Add a turbocharger on one of those and have a light little powerhouse. Not sure what it would be for weight but would be a nice package with some gessler ported heads.

    Here is the 300 blocked 349" engine I am talking about except with the iron heads and intake. it would be much lighter with the 64 alum heads and intake of course.

    Buick 400 = 600 pounds
    Buick 455 = 640 pounds

    Me thinks you've got a chip on your shoulder!! (Re: Table of Buick engine weights?)

    Howdy Sean and V-8 Buick . . . . . . dieters . . . :laugh:

    Really!?!?? You sure can bench press more than me!! :Brow:

    Okay, so that's a reliable figure for the 450 pound order of magnitude figure.

    Saved . . . . 200 . . . grams.

    Ya' know, that works out to a earth shattering . . . . 3.527 pounds for all 8 cylinders. I don't think that's going to allow you to use a different set of springs.
    :laugh:

    <o:p> </o:p>

    :grin:. . . Ooooh does that mean you know who did it? Is it the butler? :laugh:

    :grin: . . . Yeah sure, you are just trying to rub it in - aren't ya'!!

    Over 1000 hp from your liteweight champ while my assertive JW masterpiece engine is stuck on the Orinda Motors shop floor because - the wrong radiator was shipped!! :(

    Yup, I have a soft spot for this scheme. The numbers just aren't there, but with some decent aftermarket parts (or custom fabrication) you sure could make a real thoroughbred engine.

    Thanks for sharing your expertise and the good news Sean!! :TU:

    cheers, Edouard :beer

    AH, you fell for my trick.... That 3.5 pound weight savings is HUG because it is reciprocating mass... Lowering the recipricating mass is HUGE in adding reliablity and stabality for the engine especially in the high RPMs. </o:p>




    It was Bill Mah from NY who did this. He took advantage of an light strong set of rods and pistons to rev to about 7500 RPM reliably running 8's in the quarter mile with 355 cubes.

    We have to be excited about the low RPM torque you will enjoy though!

    All of the info is out there to build the above 300 based light weight engine, the only real custom part needed is the intake manifold but thats not too big of a deal. Not really many aftermarket parts to buy either.

    You are welcome, Sean Buick

    How much does a stock 300 or 340 weight?

    300 weight, according to Wikipedia:

    It looks like that info came from this webpage :Comp:
    (Or the other way around....)

    Thanks everybody!! (Re: Table of Buick engine weights?)

    Dear Sean, Erik, Bill, and V-8 Buick engine dietitians,

    Thanks for all the interesting replies!!

    I've been bouncing some "what if" emails with a few other board members for their cars and so the question was mostly daydreaming for their sake. Still I had some misconceptions that I'm glad are cleared up now.

    Good point!!

    I think for a station wagon I've made the right choice. The package certainly feels good to me.

    I must confess I feel a little guilty abandoning the original 300 in my wagon after so many years of faithful service. So I hope there will be more 64-65 owners who take up the challenge to make the 300's really peppy.

    Thanks Erik for the link. Unfortunately, I still have a hard time finding things on this board. Even with a better technique to search, you've still got to make a good choice of keywords. So I appreciate your keeping an eye on the board and providing the connection to a previous post. If you can actually provide a link to that earlier discussion, that's even better. Sometimes, you start looking at one thing and end up learning a lot more by reading all the comments on it.

    Thanks for the links. The Wikipedia info on Buick engines seems decent at least to an outsider. Honestly, I was hoping for a good table that would collect all this info in a nice compact form. It would be neat to compare say a 350 with an aluminum manifold with an all cast iron 300, just to see if how that effects the springs you have in the car. Oh well, maybe somebody will compile such a list when they are stuck on a rainy day.

    Thanks again everyone!! :TU:

    Cheers, Edouard :beer

    I have seen the wikipedia info before and I think I may have even stumbeled across the page they got thier information on when I was initially jumping into (or should I say, already taken the pludge! :Dou:).

    I'm sure it's not much, but I'm interested to know the difference between a 300 and 340, I can't seem to find the weight for a 340 anywhere.

    Re: Thanks #2!! (Re: Table of Buick engine weights?)

    Howdy Bill, Erik, and V-8 Buick engine lifters,

    I assume there is no significant difference since the 340 is a stroked-out 300. Is there some reason you can't use the weight of the cast-iron 300 as your reference?

    Thanks Erik, I'm racing through the postings and just can't take them all in. This was a very interesting thread and I missed it because I don't keep a close eye on the small block forum.

    Cheers, Edouard :beer
