Look at www.ultimaclub.us for more info.

Jay is really interesting. Spoke to them about the work involved to do that, not sure if they would do it again is the impression that I got. And of course, that car is a factory favorite

Way more work than I could ever hope to do! Hats off.

Those are the biggest vents on the vented discs I have ever seen!

It would be interesting to know the whole story on this car and how it is doing. The engine sounds nice in the videos. The exhaust manifolds look like the Maccy's. What are they doing in video 1? If this motor weighs 500lbs how much do the chevy lumps weight?

Have to check the can am project going on now too on the internet. . .

"Engine is 500 lbs. with accessories instead of 420 lbs for an aluminum Small Block Chevy."

Small block . . . like a 6,3 litre isn't small block anymore is it?

The Aston Tickford 6,3 (see frontpage yesterday's PH) would be awesome.

This is one of the nicest Ultimas I've seen. Just bumped into . . .

Could do a good 0-100-0 . . . sponsors!!!

My 6.7litre is a small block.

Looks mighty fine in yellow.

I always thought small blocks were up to 350 cid / 5,7 litres . . . Where does a big block start? At 427?

The newest small blocks ARE 427. Roughly... Small Block refers to the actual size of the block; not the size of the bore, stroke, or cavity size in the heads (which determines the total cubic inch displacement of the engine). The original "SBC" small block Chevy was somewhere around 265 cubic inches in displacement back in the mid-1950s. Over 90 million SBC have been produced since the original. As technology improved, bore and stroke size has increased, but the block's form factor remained the same (until the creation of the Generation-II small block known as the LT1 and LT4 in (?) 1992). Bore center separation remained the same. The first in the family of third generation (GEN-III) blocks is called the LS1 (released in 1997). Subsequent GEN-III family members include LS6, LS3 and LS7, with others, ranging in displacement from 5L to 7L. These blocks and heads are any combination of aluminum and iron with various cams and compression ratios.

The SBC is known, affectionaltey, as the mouse motor. The BBC (Big Block Chevy) is known as the rat. The form factor of the BBC is just that...larger. The bore centers are further appart making for a bigger block. And, it's taller for a longer possible stroke.

Another area of some confusion exists with the terms "short block" and "long block". This simply refers to the level of completion to which the block is built (when you buy it). Typically, a short block will be just the block with the crank, pistons, rings, connecting rods, bearings, plugs and (maybe) a cam shaft installed. A long block usually includes everything to make the engine run, except, perhaps, belt-driven accessories. But, missing can be any assortment of requisite goodies, like ignition, plugs and wires, fuel delivery system, etc.

Ah, thanx for the usefull info.

I found this: www.roadsters.com/bbc/

thought a Chevy 572 was the biggest block for street-use . . .

Brodix, Dart & Merlin Blocks
4.625" bore x 5.000" = 672"

Looks all pretty impressive but I think a high revving lump matches the Ultima better. IMHO 6-8k thundering machinery - like the Beemer V12 - provides the agressive soundtrack. What other blocks other than Chevys' are used in Ultimas?

Going to look at some cars that are using Porsche-power if I can get some time off between now and June.

Ah, 928 V8 in would be great . . .

thanks Chris.

Dinkel,

Been traveling a bit and missed a lot of PH time. The Ultimas in question have Flat 6's in them

With some looking, you can find them.

Would really, REALLY, like to use the 502 in something, let alone one of those bad boys!!



Dave

[dinkel]

Flat 6 in an Ultima is real yuk . . .

[chuntington101]

if you want something about 500 CID (or 600 in race form) then take a look at this.

www.falconerengines.com/prod04.htm

and then picture 4 turbos on it, or twin low mount superchargers (as shown in marrien section)! dont think it will fit though, its over 36 inch long

although, this unit also looks interesting! maybe good for racing!

www.falconerengines.com/prod05.htm

thanks Chris.

[dinkel]

It'll never fit and that's for the best . . .

New Vette unit will?
