Racer - you're probably still one of those poor uneducated people that think that Chebby's accomplishment of 1 hp per cu in with ONE engine in 1957 was an industry first - GUESS AGAIN - MOPAR did it in 1956 - a year before Chebby - and with EVERY car Desoto made - the WHOLE carline - and it was thanks to the HEMI.
The HEMI head engine is SOOOOOO much more efficient than ANY wedge- or squash-head engine ever produced - STOCK they could usually produce more than 1 HP per cu in - even way back in the 50's - and bolting that blower on top, plus modern ignition systems and carbs or fuel injection - and you're looking at a WHALE of a motor (as opposed to the later Elephant 426 Hemi)
I don't have ANY doubt that Wild can get those numbers from THAT engine. I'm just wondering how he plans on getting ALL that power to the road......
Remember - GOOD Friends don't let friends have Bow-Ties!

Yer a putz! Don't tell me about Hp/CI. Don't tell me about cylinder heads when you type the word Squash. You are a moron. There is no way that a carburated,Pump gas, 392 Hemi made 655hp. Non--zero--nada. If you think it is possible then you are the uneducated one. Its not a Chevy vs Chrysler thing. Its a technology thing. The 392 Hemi head wasnt good. If it was, the would still be in demand.... The newer Hemi is OK(I don't mean 3rd gen-That stuff is fantastic) The second gen hemi head is OK at best. It flows good numbers but really needs a supercharger to work. You are a mess. You should read a few more Hot Rod books and learn a few more buzz words--

P.S.
We arent talking about 1hp per cube. Its 1.67 @ 655hp from a 392.Good luck with that! The best superstock Hemi in the country makes about 1.95 per cube. The heads and intake cost about $17000. Go read. Read alot. Yer lost!

Talking modern technology about HP per cubic inch an example is that a friend just bought a factory crate sb Ford 302 that is 450 HP on pump gas, thats about 1.5 HP per cubic inch. I also seen several articles about worked 392's putting out over 1000 HP.

Hey Racer, You go read, Here's a quote from www.musclecarcalendar.com about the 392's in the 60's. They were making 1200 HP then.
On the technical side, due to that characteristic shape of the combustion chamber, the engine had high volumetric efficiency, extremely high thermal efficiency with low specific heat rejection and superior flow and combustion characteristics. One of the most unique facets of this design was in placing one valve on each side of the cylinder, rather than side by side on the same side of the cylinder as in other OHV engines. This allowed for larger valves (all the way up to huge valves) and that better flow that you (racers) wanted. Whether by design or by chance, Chrysler had also found combinations between bore and stroke that would lead to high mechanical efficiency. In 1955 Chrysler introduced the first car in North America to produce 300 horsepower (and 345 pounds of torque), the 1955 Chrysler C300 (3NE55 code). Horsepower for the early Hemi (again, Chrysler C300, 58N3 code) peaked in 1958 with a dual 4-barrel version of the 392 rated at 390 hp.
Sadly, in 1958, the last of the early Hemi’s rolled off the assembly line. Early drag racers and dry lake runners were already using a variety of Hemi’s because of their superior horsepower and design. Supercharged 392 Hemi’s in racing applications were making close to 1,200 horsepower by 1961. Truly astounding at that time! Contrast that with the Top Fuelers of today making 6,500 horsepower - but then again - they are still using a derivative of that early Hemi design.

That is supercharged morons. What is wrong with you people???? The 1200 HP is on Nitro. They may have been conscidered efficient then, but that was then and this is now.... and you are morons.
The article says "In 1955 Chrysler introduced the first car in North America to produce 300 horsepower (and 345 pounds of torque), the 1955 Chrysler C300 (3NE55 code).

Thats with 2 4bbls. I know how to read. Do you??
There is no possibility that a 392 Hemi made 655HP on pump gas,Period. That was my argument and I am right.....And you are still morons

I think goof ball racer is probably looking at that Hemi Rampage on that site with the tunnel ram and not the Supercharged Dakota. The Dakota has a Supercharger, Looks to be a BDS 871? to me. Hard to tell in the picture.

That's what I said, racer - it IS BLOWN - 655 hp EASY on a blown 392 - I have a friend who's building his blown 392 right now, - and he's been told by the builder that he can expect around 500 hp with his - on only 3 or 4 psi boost - still gonna be one SCARY little Deuce with that much power.
