"One of the greatest old names in high performance engines is Speed-O-Motive. Long known for their stroker engine packages and complete engines, George Ullrich and the rest of the power brokers at Speed-O-Motive are looking to show the nation they know how to make big pump gas power. Their Dart-based combo will push a big 4.170-inch bore and a 3.750-inch stroke, which means we can expect big power on the top end. Will this oversquare combo be taxed to make big torque at 2,500 rpm?

"We have great confidence in our Dart-based 351W combo stroked out to 409ci. Friction coatings will be used extensively, as will low-tension rings. The heads will be hand-ported and a custom solid roller cam will be ground to maximize the torque. We intend to equip the block with roller cam bearings to further minimize internal friction."

The Dart block is a relatively new piece, and we're anxious to see how well the entries using it will do. We know street enthusiasts are curious as to its pump gas potential, and so are we. "

Apologizing in advance..

...but reading the posting info makes it sound like this is something they INTEND to do - whereas the subject makes it sound like it's been DONE.

Really don't mean to be dense.....but which is it?

Try this link. Looks like it would make a great cobra motor!

The Jeg's Engine Masters Challenge has been concluded, but the article referenced was the only builder story in the current edition. Had found some background info on Speed-O-Motive. which is the info posted

The web site for the Challenge currently lists only the overall scores, dyno pulls have not been updated, but will at a later date which is not given.

Winner was Jon Kaase of Jon Kasse Racing Engines in Winder GA with a 410-inch Cleveland.
No mention of the HP, etc

Jon won last year for the Big Blocks with a Ford.

The Final Round was filmed for broadcast on the Speed Channel to be aired on Saturday Jan 22nd, show is " Lucas Oil's On The Edge'

..........hope this helps

Lovehamr:

Great article, I noticed the 647 HP was at 6,700 and 507 torque. The Speed-O-Motive engine had the 647 HP at 6,200, torque is 548

Would be interesting to read the same detail on the Speed-O-Motive engine.

These engines were built specifically for this contest and its rules. These engines would not be comparable to what would be a good street package. Or even a track package. Although many things done to these engines would be appropriate to increase HP in any engine.

" Commercially Avaiable "

Rules for the 2004 Small Blocks:

http://www.popularhotrodding.com/eng...ge/2004/rules/

Each section is preferenced with " commercially available " in regards to the parts selected. One of the changes from past years to prevent different in terpretations was the use of " approved " mufflers. All engines need to run on 92 Octane and with a carburetor.
