I'm a Ford fan but really didn't pay attention much to Funny Cars over the years because everyone ran a version of the Hemi. So heard Fords been playing with the Ford Funny cars engine and I was wondering what the spec are? Everytime I do a google search all that comes up is Force stuff. I'm a Ford fan but not a Force fan. So what is the engine in the Ford Funny cars these days?

Thanks,

The BOSS500 is based on the 426 Hemi.....bore spacings and such are "written in stone" by the Gods at Glendora and they are the same on his motors as they are on anyone else running a nitro hemi. (Read spec engine) I believe I heard that the mains have a Ford p/n on them so that way it "qualifies" as a Ford fuel hemi. I don't understand it, but that's the way is was explained to me.

The heads are redesigned and also have Ford p/n on them.:)

it's a damn HEMI! i have looked at it up close. My gear drive, mag drive, oil pump, and valve covers will bolt right on his motor. Since when did the FORD hemi have the mag and oil pump 45degrees from the upper right to lower left side in line ? With all the money Force gets from FORD, wouldn't you think it would be a smart thing to call it a FORD motor! They do produce their own heads and many components in the motors so technically he can call it whatever he wants.

Carrol Carter sells the ford hemi block and heads. years ago it was started by Chuck Seyler. a few teams used it and even a couple pro mods did. But NHRA outlawed it because the bore space is bigger than the 4.84 Chrysler hemi. Pat Austin wanted to use one in a ta/fc and said he could make more power because the design is better than a hemi. that was when NHRA said NOPE!

So Ford is building Hemi Engines using Chryslers fifty year old design? WOW. Who invented the internal combustion engine? Since Ford shouldnt be calling their "Hemi" a "Hemi", Maybe Dodge shouldnt be calling their engines.... "engines".

I guess Mopar should be raising hell about this. I mean the development of the Hemi is the last thing worth a fuck Mopar has done. Oh wait...they started the mini-van craze with the Caravan. My bad.

as to your question about who invented the internal combustion engine it was robert steele in 1794.it ran on coal dust and resin. it was placed in a boat way before henry ford was born.the word hemi as referance to an engine design is a trade mark that mopar owns

Yeah , I remember Chuck Seyler testing at GLD. Too bad the motor wasn't approved. 'Course all of our tracks
might have been too freakin short years earlier. And for you mopar/nocar guys, I think Chevy had a hemi in
like 1912. They probably weren't the first either...

It is all about marketing ...ford give force alot money...does not want to hear chrysler hemi ...force takes chrysler hemi changes...main bearing...paints it blue with ford decal...calls it a ford boss hemi...take a close look at the engine and if you know what a chrysler hemi looks like...you will see it ...under the ford decals....

nhra engine specs for a fuel engine is based on the chrysler hemi....no way around it...

I thought Ford uses a different head, the head bolt design is different then the chryslers, and the Ford block was designed with more rigidity in it especially in the lifter valley. An old timer that used to work for Ford told me that the "hemi" was proposed to Ford before Chrysler but Ford turned it away. He said that Chrylsler more or less ended up with it because no one else wanted it. I dont know if its true, but I have been proved wrong a few times when I told him he was full of it and had to eat crow.

So are we talking planes and tanks, or the internal combustion engine. I though we were talking cars, the Ford flathead was the first american car engine to have hemi cyl head produced for it. Hemispherical engines have been in automobile engines since 190x and before that in internal combustion engines of other ventures. Long before Chrysler thought they developed it.

My working knowledge came from the people that I have learned from. You already knew that, just like you already know why those people are the reason NHRA(and other racing orgs.), banned their Ford Hemi combos.

The Mopar pro stock hemi has Boss 429 heads on it. Therefore the new Ford pro stock engine is only using it's own basic technology. The ARDUN hemi conversion was the first American pushrod hemi V8 that was built in decent numbers. Therefore all funny car and top fuel engines are based loosely on the ARDUN Ford V8.

Back to the origional question, which I think was what seperates a BOSS 500 from a BAE or TFX....I've worked on a few TFX's and BAE's. The front cover stuff is totaly different, so I would imagine the BOSS 500 is way different from both of those two, since there is no standard. The oil pans won't interchange between a BAE and TFX so I imagine thats different too. If you've ever done the bottom end you'll like the TFX a lot better since it's wider down there, but you'll soon hate it when you have to take the oil pump off to check the front main bearing. Unless you take the bolt out and just put a plug in there (Johnny West tought me that) on the oil pump side. The TFX also has side bolts on the rear main, but they are not really an issue. Heads, cam, crank....they all interchange.
Who here has actually worked on a BOSS that can shead some light on this?

Having raced alcohol funnycars for twelve years,my only engine was a supercharged late model Hemi.
The Force Hemi is a marketing ploy.Same bore centers and cam to crank centerlines as the Alan Johnson Hemi.
Force,Schumacher,they make their own "consumable" parts now.Blocks,heads,chassis,clutch discs are a few.
And it makes sense from a business standpoint.Keep it in house,control the costs,and inventory.
Both these race teams have many CNC machines,that do nothing but churn out said parts.And they also repair everything in house,also.
You would'nt believe the inventories at the shops and in the trailers.

You are absolutely right. It seems we have the two biggest Chrysler Hemi fans on the bullet and they havent learned/realized Im only on here for a great laugh tonight! Man I wish I could get some parts to start putting my race car back together, this just isnt as much fun!
