584 ft-lbs at 4500

610 hp at 6400

And it's a small-block

Check it out, on page 40 in the July issue of HotRod

Very cool :cool

Only $10,500 with aluminum heads...

2.250" bore

??????????????????????????????????????

 

[MaineShark]

Sorry, 4.250" bore.

Duh...

(fixed it)

I saw that in the magazine. For someone who doesnt have a numbers matching engine, and is trying to decide on rebuilding or buying a new motor... the choice is a real easy one. Thats some mega power from a small block. Plus...you get the weight savings over a BB motor.

Joe,
454 smallblocks are cool aren't they?? you can build the same thing in aluminum block for two grand more, hint hint. all parts are availible from GM performance, perfect for your megga motor prodject. Brian

 

[SwaveDave]

How much weight savings is there on a SBC vs. a BBC ???

Brian,

How close was the Valdez Oil Spill to where you are ... and is finally cleaned up ??

Joe, you forgot to mention a key point with that package, namely that both the iron and the aluminum head versions carry a 2-year or 24,000 mile insurance policy that covers up to $4000 in repairs. "... 24,000 miles? Yup--they run on 91 octane and they're designed and built to drive forever."

I felt like crying though when I first saw that motor; I'm not even going to tell y'all what has gone into mine so far, but it's a long ways from the prices quoted for those mice. :eyerole

Of course, I could always console myself in the knowledge that nothing, NOTHING, is ever what it seems; there's always going to be something more you have to add. They simply don't mention those items, and the cost of those items adds up quickly, believe me!

Ken,

Id be very curious to know what other additional things would be required on that 454 sb engine ??? It sounded pretty complete in the magazine --from carb to pan. I wonder if they would be willing to exchange the tappet cam for a hydr. roller and the single plane for a dual plane intake ?? Thats about the only other thing id like in the package.

Last summer, i had my BB totally rebuilt . I bought all the parts and my mechanic was willing to assemble the motor . It still cost me nearly $7,000 by the time i was done. If it wasnt the original block, id have spent the extra and gone for something like that 454 sbc motor .

Dave,
the small blocks are about 150#'s lighter than the big blocks. i can't remember off the top of my head, but someone will provide an exact number i'm sure.
as for the spill, it was right outside the port. the reef is about 25 miles from town and all the oil went out toward the gulf instead of toward town. greenpeace and the rest of the bunny hugger media kind of blew it out of proportion. 99% of the effected shore line was shear rock cliffs and the clean-up was all but complete that summer. the winter storms and mother nature took care of what was left. the next summer it was nearly impossible to tell anything had ever happened. it was impressive to see a 1200ft tanker grounded though. a buddy of mine was a diver that originally inspected the damage to the hull. he had some pictures that proved it was big enough to drive a truck through. if you want any more info on it, i'll be glad to send you some. i don't want to sidetrack this thread, so i'll shut up now, Brian

Yeah, 454 small blocks are very cool.

Been done before, though.

So, why did I post this?

Check out the bore and stroke

Not the typical 4.190" bore used in most 454 small blocks...

4.250" x 4.00" is the same bore and stroke as the big block. Should make for a nearly identical power curve.

Thinking about it, you know what else would be cool? Go bigger 4.125" stroke would give you 468 cubes...

Scary

What finally made it possible Joe, according to the article, was the release of the new head gasket from FelPro (4.25).

Yup. I think that's pretty much the ragged edge, for bore diameter on a small block. I mean, the web is only 0.150", if I did my math right. I don't think you can cut much more out of that, without seriously compromising integrity. I think it will already have an issue with running hot in the web areas, which would limit the compression that could be run without detonation.

So, if the stroke was also bumped a bit (and 4.125 is near the limit for stroke, as well), that would put an effective limit of 468 on small-block displacement. Not that it couldn't go a bit higher, but that's insane enough for me

Mmm... 468, all-aluminum small-block... that would be most gearheads' wet dream, I think...

It sure would draw crowds at shows and cruises!

it will deffinately draw two very long black marks on the highway!!!!!!!! oh my the fun factor just got upped a bunch, Brian

 

[1BAD80]

With the aluminum block you can build a pump gas 504 small block Sonny Leonard built one a couple of years ago the the magazine , 1020 HP on the dyno.

If they could see it - blink, and you'd miss it
