2013 Cobra Jet Specs are up

[D.Johns]

NHRA posted the 2013 Cobra Jet specs up yesterday. Enjoy

302 NA 350HP/3017#
302 SC 500HP/3170#
363 NA 330HP/3100#
427 NA 425HP/3150#

Have you looked at any of the specs? The 363 should be a killer combo with that ridiculous rating of 330.

[D.Johns]

The 363 basically the same as the 2010 CJ 352/285HP(currently factored 302). It has a slightly bigger bore combined with 0 deck block bumped the compression up to 11.5 it appears in the tech specs.

The one that surprised me(because I'm building one lol) is the 2.9/5.0 SCJ. SS only. I was hoping to do some battle with the 2.9/5.3 COPO. Dang well there should be a couple step up to SS before long given their potential and specs.

Not nearly as soft as the '10-'12 combo's. Which should make everyone but the ones building the cars happy. I'm kind of glad I cancelled my order for the Competition Kit I was going to build. Which I was going to build as a '10-'12 352/285 stick combo instead of the 5.0/350 anyway. I know the new 5.0 is a bada$$ motor but to my knowledge the NA version is factored right out of the box harder cubic inch to hp than any other engine in history. Correct me if I'm wrong. I don't know if Ford is being more straight up when asking for the ratings or if NHRA is finally taking a stand? 302/350 = .86 cubic inch per hp factored. Someone please show me a NA combo that came out of the box factored this hard. To be honest all for of the combo are factored hard in my opinion.

Ok... Just running the numbers again.

The 302 (5.0) NA 3017/350 = 8.62 natural B car until it gets 5 hp.
3017/355 = 8.49 making it a natural A car. I don't see this combo competing with '10 428 combo in A.

The 363 NA combo. 3100/330 = 9.39 making it a natural C car. Probably the best combo they've got here. It would need 15 hp to be a natural B car.

The 427 NA combo. 3150/425 = 7.41 making it a natural BB car. In my personal opinion this combo would not run with the '10 428 combo.

The 5.0 SC combo. Well I'm not a SC kind of guy so to speak but coming out of the box at 500 hp is pretty steep in my opinion as well. I would really like to know what happened between Ford and NHRA here. I guess Ford had to throw them a bone?

The '10 352 combo 3130/285 = 10.98 making it a natural F car until it gets hit 13hp to 298 hp then its a natural E car.

The '10 428 combo 3305/375 = 8.81 making it a natural B unit it gets14hp to 389 then it will be a natural A car.

So you've the '13 5.0 NA version competing in B against the '10 428. I don't understand.

The 5.0L SC combination was mistakenly listed as SS only. I had a conference call with NHRA tech today and they are aware of it. We are looking forward to healthy competition with the other brand's SC offering in Stock.

These hp ratings are definitely closer than the 2010-12s were. You have to respect Ford for going in the right direction. The 363 is probably needs the most hp out of all of these, but at least it wasn't 285 like the 2010 version!

I don't know why anyone would build the 363 or 427, though, when the 2010 versions of those motors are rated so much less.

Great news there. Leaves me a few options then. Looking forward to all the great competition out there.

Cubic inch per hp the 363 is pretty close to your combo. 363/330 = 1.1 cu/hp vs. 350/325 = 1.07.

I'm sure it will eventually get hit but it looks like the best combo they've got for '13.

Jesse,
Did they get the pulley size correct? 3.97 upper? Lower has 8.125 for the Inner? And 7inch for Outer??? Was the drive system reconfigured from the single belt?
