    That was awesome information. A 350 SBB can do over 1000 hp. Now, if I only had thousands and thousands of $ to duplicate the little engine. Wouldn't it be great to whip up on some BBCs with a little door stop engine?

    While it would be stupid to even pretend that Bill's engine does not have megga bucks worth of parts and engineering in it, you may want to read the entire thread a little more closely...

    Stock 2 bolt block- no girdle or halo!
    Stock intake manifold- tho ported to the max!
    Stock iron heads- ported, of course!

    The [only] really trick pieces in his engine are the crank, rods, and pistons,,, also custom head gaskets... And of course we cant forget about the supercharger

    What's really important to remember here is that the little [and at 400 lbs, I do mean little!] buick 350 is up to the challange of making some serious #'s

    I mean anyone can build a 1000 hp by opening up a summit catalog, and slapping a blower on top of a 426 hemi,,, but to get this kind of power from an engine that most people consider a "door stop" is a major step forward.

    Look at it this way- When was the last time you saw a BB chevy, 440 magnum, 455 GS, or for that matter- an LT-1, or 351 C 4 barrel at your local junk yard????? Factory performance engines are becomming extremely rare, and the day is comming that if you want to build an "old school" RWD performance machine, you may have to look at an alternate power source.

    The Buick 350 is cheap, pleantifull, and now, UP TO THE CHALLENGE!!!!

    This is a great day in the buick performance world.

    Guess the GS 350 cars may just be superior to their BB brothers now.... Wow, a 71 GSX 350 with a 1000 HP 350 motor .... endless possibilities now...

    I wonder since it was done to a 350 SBB, what the potential of all that work and money could to to a 455 BBB? I mean I think this very awesome that such serious power could be brought out of such an "under-estimated" motor, which makes it a day in history to remember, but im wonderin Very cool indeed.

    I would have to say ask Hendrickson about this one. To me, with the stock block, as used here, a 455" would make one of the biggest messes any of us have ever seen in regards to a engine explosion. The 455" is weak, we all know that. My opinion, NO WAY you boost one like this without a fill of hardblock, a couple girdles, etc. Wasted money I think. You have to have a aftermarket block for a set up like this in a 455". I have recently heard of some 455's wrecking blocks in the mid to high 700 hp range. And thats with all the goodies.

    I just want 700-750 hp for my new car, that will live. I can use a $4000 aftermarket block, or a free 350"...... For the price of the block alone I can have a set of rods, aftermarket crank, and a few other pieces for a 350". I already have the turbo for our project.

    Granted, when the new blocks start getting shipped, the numbers are gonna be huge. There are a couple really KOOL motors in some back rooms waiting for them. The info I have been told............WOW !!! But if your like me and just want 700 ish', not tough, and if our numbers all work out, NOT expensive either.

    I would be very excited to keep my current power plant and not need a 1000lb diet to be able to move off the line like a tiger.
    I would be dreaming but a 500hp kit that you didn't even need to pull the motor would be nice. ZZZZZZZZZZZZZ

    Cool, thanks for the information! I was kinda wondering why many haven't brought it up but now I know.

    This needs to get into the car magazines!!

    Lets keep the ball rolling with the SBB!

    OK, I'm a little selfish. I want a single plane intake and roller valvetrain - 500 HP is enough for me!

    Rock on SBB!

    Hey man,

    Don't just go on my very little info I spouted there. Just do some homework for yourself. The 455's have block problems, meaning they're weak. My personal thinking was that the 350", like the V6's, with the deeper skirts would have to be stronger. I feel that is being proven now with Bill's motor.

    Don't get me wrong, this motor is FULL of some good parts, and expensive ones at that. But, I feel that substantial power level can be reached without going to the extremes that has been attacked with this one.

    As more information comes to light, I am sure we'll all see the great effort put forth within this motor to make the power we have seen now, AND the dedication in regards to the parts, assembly, running, etc. I really think this is a fantastic tip of the icebergh for us. And I know, I am very enthusiastic about my 350" turbo project now.

    All is true, I think the more people experiment with the SBB the more possibilities and potential opens up. And before the SBB boom opened up I have had plans for a SBB before this had all showed up. Now it is a defenite must for me. Though im far from being rich enough to get this power, or even just the 500 HP kit, it seems to be all in the figuring and tuning of the motor that makes it all possible. In the future, my project should have amazing numbers with a sbb 350! Ah, the sweet dreams

    Rick,

    You "gotta" know that the car is in pieces now, what with the change from BBB to SB ?? Well, to say the least, the front is completely off the car, AGAIN, lol. I have some firewall work to do, paint looks awful, etc. etc. The doors are back on finally so thats a plus, but, all the front steering is off, haha. I will try and get you some pix when its just a little more publically presentable. Just keep on badgering me, and I will stay motivated...............

    Dave, my tubbed 67 is the same way. Well, almost. I put my front clip back on (with about 4 bolts) when we moved a few months back.

    Actually.... I would probably even prefer to see your car still tore apart. It's the "nuts-n-bolts" that I'm interested in seeing.... not the pretty paint job it'll get someday.
    But don't worry... I won't stop badgering you.


    Sorry to steer this thread off subject....
    Regarding the 1000HP 350.... What kind of torque numbers did it produce? And at what RPM?

    A few months back I got to see Dave's 67 up close and it is going to be one serious vehicle when it is done.

    Congrats on the accomplishment. People getting excited about hitting just over 175hp per liter is silly!

    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!!!

    Do you want to really let it get its legs extended,we've got a pattern for a 350 girdle,a billet one is on Sonny's 350 ,prolly only one in existence.Maybe if a lot more folk are interested in this "huffer" build up a run of the girdles could be made to keep costs down.
