2010 Mustang Stocker

[Rich67stang]

Can I run a 2010 mustang with a 352ci rated @ 285hp in stock with a stick?

10.98 x 285hp +170# = 3299# would that put me in C/S

Thanks.

10.98 is a natural F/S. You could only drop as low as E/S.

I knew I would get this all wrong!...lol. So, this combination is legal? how did you come up with F/S? Am I correct with the factor and weight?

Thanks again.

10.98 = a 10.5# class which is F

So 285x10.5+170= 3,162.5# min. weight for F

then you can move up or down one class so

285x10+170= 3,020# E min. weight

285x11+170= 3,305# G min. weight

Now these are the class minimum weights without nitrous. You have to weight at least the minimum of the next class up with nitrous. So if you were running as an E car with nitrous you would have to weight F's minimum. If you are from the Bayou that rule doesn't count.

Yes, the combo is legal and in the guide. It should fly! You can go to the class weight breaks here. 10.50-10.99 is F/S (or F/SA). You don't do the math to find the natural class since you already had the weight factor of 10.98 listed in the class guide.

I forgot your weight question. For F/S you would need a minimum weight of 3,160 lbs. Here's the math.

10.5 x 285 = 2,992.50 You round down to the nearest 5 lb increment, so....

2,990 + 170 = 3,160

Guys,

I'm new to the world of Stock and Super Stock and I'm now confused. I'm not aware of a 2010 model mustang that came with an engine even close to the 35X cubic inch range and am sitting here wondering how he can run in stock? Especially with a stock crank and stock dimension rods?

did I miss something when I read the rules?

Thanks,

Hey Scott,
Welcome to NHRA I know you are or were a NMRA guy for quite awhile. If you click on the NHRA Competition link in the header above and then go to stock car classification guide then go to Ford 2010, Mustang it will give you the NHRA accepted options for that year, make and model. The 352 and the 428 options for this year were paper motors that came in the 2010 Cobra Jets only. These are pushrod motors the 352 is a 302 based engine and the 428 is a 351 based engine. In the same area were you find the stock car classification guide is also the engine blueprint/spec guide. Do the same there Ford, 2010 and it will list part numbers and specs for the engine of your choice. Hope that helps.
