All Fuel (Nitro) motors in the NHRA are currently based on the Chrysler 426 Hemi design, Forces included. They are bored and stroked to displace 500 cubic inches. They burn up to 90% nitro and make 7000-8000 horsepower.
The only thing Ford about Forces cars are the little stickers on the carbon fiber body.
i realy dont see where drag racing has any bearing on a company. The parts are soo far off from anything that will ever be mass produced and 90% of the stuff comes from a third party manufacturer anyway. About the only direct crosover from racing to production is the Wenkle Rotor in the RX7s and 8s
my truck is twice as old as me!
The heads on those cars are very loosely based on the old Hemi design. They are actually probably closer to resembling the old Boss heads than the Hemi heads. The basic design is there, but the valve sizes, angles, and especially the combustion chamber are totally different.
2001 Ford Lightning
JLP built block, Patriot Stage 3 heads, JLP stage 3 cams, Kenne Bell blower, Kooks custom headers, Bassani catback, etc., etc. 619.8 RWHP.
So what you are saying is the fords are all running the chrysler motors? What is up with that? If they are running chryslers then why is it in a ford. From the post it also sounds like the top fuel engines are also chrysler hemi's?
How did this come about? Why doesn't GM and Ford engines compete at this level?
They are niether ford, dodge, or chevy by my understanding. But totaly custom all alluminum blocks designed loosly on the old hemi pattern. Their are no cooling passages in these blocks just one big chunk of machined aluminum, any cooling passages would take strength away and running the fuel them do that would be a possibly deadly combonation.
Weather say dodge ford or chevy on the side it dosent mean much. Not one single part on these cars is the same as what you get in your avearge mustang cavilier or any other production car or truck.
Actually, the combustion chambers are nearly identical to the 426 Hemi heads. I'm 99% sure the valve angles are identical to the 426 as well. The crank shafts will interchange as well, even though the fuel motors have longer strokes. I know a few people who have run used Fuel cranks in 426 blocks.
Here is a pic of a Brad Anderson Aluminum Top Fuel cylinder head. If you compare the chambers to that of a 426 Hemi, you will see they are nearly, if not completely, identical aside from the dual plugs. The Boss heads hade quench areas on the sides of the chambers, unlike these which are completely open just like a 426.
It is true that the blocks and heads are all aftermarket parts made from solid aluminum though.
