Yep.

Those V-6 cars can run mid 13's with longtubes, off road exhaust, stock gears, and maybe a CAI and tune. But if you want to run 12's then things get serious.

Since it is a small naturally aspirated engine pushing a lot of weight it will not be an easy build to run index.

Might be factored too high

I think some of them run quicker than that.

And I strongly suspect that on race gas, with open headers, a loose converter, 4.56 rear end gears, and lightweight drag racing brakes, that the index should be much more attainable.

Yup.

I mean, the converter would have lock-up, and the transmission has two overdrive ratios, but dang...

Can I get clarification on the Cobra Jet issue?

In sifting through the Stock Classification Tool, it appears that the Cobra Jet is listed as distinctly different vehicle than the regular Mustang- the Cobra Jets are listed with their respective engine(s), the Mustang GT is listed with it's respective engine(s), and the base Mustang is listed with it's respective engine(s), and I'm not finding the 2.3 Ecoboost or 3.7 V-6 engines listed as being eligible for competition in any Cobra Jet.

Can somebody clear this up for me?

The main difference between a Cobra Jet and a base Mustang is the motor combination. The way that the rules are now there is really nothing else except the weight breaks. Maybe the hood?

[GUMP]

To make my COPO into a Camaro we built the right motor, put the cowl stuff in, and installed a flat hood. Other than that we added a weight bar to bring it to B/SA weight.
