2012 Boss 302 in NHRA Stock Eliminator

Just a guess, but you don't see regular production cars from the Big Three because they don't submit them to NHRA for classification. It doesn't matter what's out there, if it's not in the guide, it's not legal for Stock Eliminator. That's why I still believe you can't build a Cobra Jet out of a regular production Mustang, because there are too many unique parts and modifications to make the conversion. The only 2012 Ford in the Guide is the Cobra Jet, a limited production vehicle

Just my opinion but putting the 302 in the CJ body amounts to being a crate motor car, nhra has said that will not run crate motor classes than how do they explain this.

There are Cobra Jets out there that started life as 6 cylinder mustangs.

If that is the case, I stand corrected! I had thought that the "Cobra Jet" was a unique model of the Mustang for 2012, and that just adding a Cobra Jet engine to a regular production Mustang wouldn't make that car a Cobra Jet.

Evan is right. Take a 1970 ford/chev/dodge at it's factory rating (.65...maybe.75) and build it to make 1.5 hp per cube and you got a runner.
Take a 2011 ford/chev/dodge that is factory rated at 1.3 for example, what do you have to do make 2.5-2.8 to be equal?

Weight is also an issue, a lot more **** can come out of a new car compared to old ones so that helps and the chassis are more rigid than ever.

I don't neccessarily agree with .65 factor on new engines as they are inherantly more efficient, BUT, you can't start a car out at 1.3 or 1.5 hp per cube or no one will build it.

Just some numbers of old random combo's;

77 Cad 350 180hp .51 hp per cube
76 chev 305 190hp .62
74 chrysler 400 290 hp .725
70 dodge 318 185hp .58
73 ford 351 240hp .68
72 ford 302 162hp .53

and some random new combo's;
2012 ford 302 325hp 1.07
2010 ford 330 435hp 1.32
2011 dodge 512 450hp .87
2010 dodge 345 305hp .88
2010 chev 376 400hp 1.06

My conclusion would be that the newer engines compared to older engines are starting out higher before any adjustments than the older stuff did. Slight mind you (.8 vs .6) but higher none the less.

This just leaves less "room" for improving. I don't want to build a 2bbl 302 at 300hp to start out with, but at 162? lots of room there. Do I want to start out with a new engine at 1.3hp per cube...to START with? Uh..no. Put it at .8 or so and then hit it as it's improved....like every other engine in the guide has done

I appreciate everyones reply's. I never thought about the factory's HP rating, and what this thing would have to weigh when I first thought about this. And Evan's point's about efficiency are spot on. You can look at comparing the valvetrain of a 1968 302 set-up, and then look at the modular 7500 RPM plus set-up. Enough said. Now, just what to build with this 2009 BIW thats sitting in the garage. Thanks fella's

Send it to MPR and tub it and 4 link it. Put a clutchless 5 speed in it with a 5.4 supercharged motor and go super stock racing. That was an easy question to answer.

Chad,

The LS-1 engine also started somewhere around 325, not 426 like the current LS in the 2012 Camaro. That's a 100 hp difference!

Lew,

It is not the responsibility of the manufacturer to send in the specs for all new cars. They have better things to do these days, like figuring out how to keep afloat. If a racer requests that a combination be submitted, then the manufacturer will do it. There are people at Ford, GM, and Dodge who handle this.

Yes, this requires some legwork on the part of the racer.

Fuuny you should say that. I spent approximately 30 minutes on the phone with Mike on Wednesday
