I was just wondering what everyone knows or thinks about this engine. I've heard it has 600 claimed hp, but what about torque? Also, do y'all have links for anyone that sells it or know what the ballpark price of this monster is? Thanks for the info...

This engine is said to produce 560hp @ 6000 RPM, and 535 ft lbs of torque @4750 RPM. It runs 11.5 to 1 pistons, so pump fuel is out of the question. Retail price is $5495.00 not including induction, ignition, or exhaust manifolds. Any Ford Motorsport dealer can get you one. You probably cant build a comperable engine for this price, but it seems a little non-streetworthy. Ford Motorsport offers more streetable versions of the big block for less $. (Im assuming you are looking for a street motor, not a bracket race motor). Hope this info helps

When you say no pump gas, do you mean regular unleaded, like you have to use premium, or do you actually have to purchase special gasoline? Just curious.

 

I seriosly doubt that a motor with an 11.5-1 compression ratio could be tuned to run on even the best pump fuel available. That motor would rattle worse than a deisel, and be very short lived in the piston department. Most stock motors today run a 8-1 ratio or less. Your best street set up to run pump fuel is probably a 7-1 comp. ratio and a street supercharger if you want serios power and dont care about $. If anyone knows how to make an 11.5-1 motor run on even 92 octain fuel, please let me know and I will order the parts to do it. Compression= Power!

Maybe Nathan has a newer catolog, but my 1999 book shows 600 HP @6259 RPM and 590 ft./lbs. @ 4750 RPM
The catolog says the compression ratio is 9.8:1 which is possible to run on 92 octane with aluminum heads (you can usually run half a point higher with aluminum than cast iron). Also if your willing to put up with some "grief" you can run 11:1 or higher on the street for brief periods. 1. Convert your carb and fuel components to burn alcohol. Alcohol is around 108 octane and also increases HP by 7% 2.It's illegal but you can purchase aviation fuel for "off-road" use: octane rating around 100, price between $2-$3 a gallon. 3. Find or make the "old" water injection systems sold in the 1970's. Use 92 octane fuel and you can probably run 10.5 or 11:1 with cast heads. Caution: extended periods with water injection with cause pitting in the valve/head area.

 

My information came from the September 1997 issue of Car Craft mag. Im sure things have changed since then. The 9-1 motor you speak of sounds like a more "streetable" motor, although I think these motors are built with bracket racers and show car "trailer queens" in mind. To me, this motor sounds like a pain to drive much on the street, and I prefer to drive my trucks. To each his or her own though. Good luck with your "Big Block" project!
