The money thing comes in when a guy sitting at the club has to say "I've got a 600 inch SBC" and the ensuing pile of bullshit flags that are gonna get thrown.

    It looks on paper to be closer to a 400 M Ford than any SBC I've ever seen... and let's talk about those heads.
    I agree, it had to be built for some purpose..... even if just to impress....

    I'll never understand why money ever enters into the conversation. Actually, not even sure why it's here now.

    To me, this is what typifies what is wrong with our hobby in general. As was mentioned above, those of us down here at the BS level don't have cubic dollars to invest in our rides, let alone just in an engine.I personally am more impressed with the guy who builds his stuff in his own garage, only farming out the stuff he absolutely cannot accomplish on his own. Here's what I have for an engine for the "Whatever": Click image for larger version

ID:	1289001 I call it Old Mangy currently. I'll rebuild it eventually, however it will run now, its just, well Mangy on the outside.

    I've seen threads where people have started with less and spent next to nothing to get a decent runner, be it a 305, a 307, a 350, a 283, whatever they have. Now LS engines are getting old, and they make good power cheap. The Ford guys still use 302s and they are still available and affordable. And classic engines like the flathead can still be done reasonably, if you want to have less hp than a Honda! Don't get me wrong, I low the beat of the exhaust note a flathead makes. I gave my last 2 blocks away 4 years ago, knowing I don't have another build of one in my future (wellmaybehelp my brother and his son with the 59 A block I gave him almost 40 years ago). They have plans to build an A Phaeton on Deuce rails someday.

    So at the top of the hobby we have the proshop built cars that cost not cubic dollars, but dollars to the 4th power. Then there are some really nice cars built with sweat equity and ingenuity, that won't put you in the poor house. I like them both, but I choose the latter for myself. Besides, for me its the time in the garage building as much as I can that's the draw.

    Here’s the 400ci Chevy from the ’70s. It was the best factory option to go big, but the largest displacement realistically possible was 434ci.

    Prolly just a typo bit the 400 is pretty commonly taken to 454.

    you say that but to get 454, you have to move the cam up in the block....

    people still make fun of the 305.

    I am still driving one at 387k miles.
    facts don't have slipping automatics, you know what I mean..

    anyway, cool engine, but again, its a maxxed out siamesed overheated tortured .25 mile animal.
    I don't like it.
    you realize that the LS motors are all siamesed?

    there, fixed it for you.

    For the current generation of 358ci engines, NASCAR allows 4.5-inch bore centers but restricts the maximum bore to 4.185. The extra distance between cylinders give engineers more room to circulate coolant — in other words, no need for siamese cylinders and more durability.

    to me - the bore spacing knocks it out of the SBC category

    I agree with SBG...NO... It's akin to calling the current NHRA top fuel motors Chrysler Hemis.... No offense intended, just sayin...

    Rich bastiches to start bar room bragging arguments? I mean, it's got some merit for that, but how many of us down here at BangShift! level are gonna pony up 30 grand for a block and two heads that needs custom everything else? I can only imagine that mill eating 50G before it barks in anger. The Coyote, LS, and Gen whatever Hemi live at pretty insane power levels for a mountain less coin.

    Steve Strope or Chip or Troy, or that crowd, and the guys they sell to seem like candidates. It's neat stuff, just not a SBC.

    Basically, folks who have liquid nitrogen cooled checkbooks and need to say this about their "SBC":

    The big reasons I'm voting not an SBC:

    Will it fit any standard SBC crank?
    Will it use any standard SBC timing chain?
    Will it fit any standard SBC head?
    Will it fit any standard SBC Cam?
