The top Challenger is the SRT-8. The Mustang has the GT, Boss 302, GT-350 and GT-500 which one of these Mustangs are compatible to this Challenger 392 CI 470 horses?

The GT, Boss, and GT500 all outperform the Dodge SRT 8.
The new Mustang is an amazing platform. Bolt on a TVS supercharger and drags to a base model GT and run high 10s in the quarter, auto or manual.

I test drove a new 2011 Mustang GT 6 spd. It is a real screamer scary fast and alot faster and comfortable than the Fox body 5.0 Mustangs which are very uncomfortable on these bad roads. However, brand new factory order was only $16,000 at that time

I think the advantage as far as I am concerned is that the Challenger SRT 8 will have a smoother ride and is a bigger car with more space, longer wheelbase than Mustang. But they wanted $40,000+ for that GT
They also had a GT-500 vert on show room floor for $90,000

The new Boss 302 may be the best Mustang ever produced. Very tempted to get one.

Love the graphics on the Boss. But I think the SRT-8 will be a bit more comfortable to drive.
Not to count out the CTS-V but that is in the $60,000 range.
