533 HP on the dyno.
 

I posted a photo a week ago of a flathead Ardun conversion at a local car museum nearby me. Here is the dyno run video. Too short but pretty cool.

WOW!! That was really cool!

Re: 533 HP on the dyno.
 

that's absolutely crazy numbers from a flathead.

Re: 533 HP on the dyno.
 

Only thing is, it's no longer a flathead! It's an antique Ford block with aftermarket overhead valve hemispherical aluminum heads.

Re: 533 HP on the dyno.
 

Yep

Re: 533 HP on the dyno.
 

I wonder how much $$ was put into it??

Amazing

Re: 533 HP on the dyno.
 

If someone told you a supercharged Hemi made 500+ HP it probably wouldn't impress you very much.

Re: 533 HP on the dyno.
 

At $49K priced right.I got over 1/2 that asking price for a mint complete original set of Ardun heads only w/ intake and exhaust manifolds in 08.

Re: 533 HP on the dyno.
 

500hp on three main bearings....

Re: 533 HP on the dyno.
 

But for how long?!

Re: 533 HP on the dyno.
 

With Rick's bottom end, a very long time. Schnell knows flatheads.

Re: 533 HP on the dyno.
 

a lot!

Re: 533 HP on the dyno.
 

Fantastic numbers ... curious - are Ardun conversions actually not considered flatheads?? I thing SCTA Bonneville has them as a different class that does not compete against a flathead??:confused:

Re: 533 HP on the dyno.
 

Flatheads are L-heads...Ardun are overheadhead valves.

Re: 533 HP on the dyno.
 

Yeah, but your engine likely doesn't have all of the extra engineering, parts, and work that went into this Schnell-built engine.

Re: 533 HP on the dyno.
 

It was built by Rick Schnell here in Minnesota. Its based on a 1951 Merc block. Here is another view. The thing is so shiny its hard to photograph.

5000+ RPM's - 533HP - 488 FP's of torque

The only thing that beats cubic inches is cubic money.

Re: 533 HP on the dyno.
 

Awesome numbers!!
I wonder how much boost!!

I wonder on the boost too. I am going to use a 6-71 on mine and everyone tells me it is to much. I see that it works! I do see he's under driving his.

Re: 533 HP on the dyno.
 

This info was below the vidio:

"Original Ardun heads, 6-71 roots 13psi, 6 Strombergs, Built with the same bottom end as the Slider Blown fuel flathead dragster."

Re: 533 HP on the dyno.
 

Yes, but a Hemi that is more than likely under 300 cubic inches and 13 psi boost, it's pretty darn impressive .
