A 1965 Pontiac GTO, '69 Shelby GT500 428CJ, '71 Plymouth GTX 426 Hemi, '70 Buick GSX. They're all in your dad's fantasy garage, and they're among the cars included in a free DLC pack Forza 4 Season Pass holders will get if they pad Microsoft's cash-flow up front.

Microsoft's Turn 10 Studios announced Forza Motorsport 4 Season Pass holders will get six DLC packs between November '11 and April '12. The total sums to 60 new cars downloadable for $30 (or $39 individually), with a special American Muscle Car pack (available on day one) as a season-pass bonus. Also, who am I kidding? These cars will be awesome. Here's the full list of muscle cars in pack 7:

* 1965 Pontiac GTO
* 1968 Pontiac Firebird
* 1970 Buick GSX
* 1970 Dodge Coronet Super Bee
* 1966 Chevrolet Nova SS
* 1969 Shelby GT500 428CJ
* 1971 Plymouth GTX 426 Hemi
* 1967 Dodge Coronet W023
* 1968 Dodge Dart HEMI Super Stock
* 1964 Ford Fairlane Thunderbolt

Forza 4 is scheduled to hit on October 11 — now including the Indianapolis Motor Speedway — with a demo arriving October 3 for Xbox Live Gold members (October 7 for civvies).

Full Disclosure: Turn 10 Studios and Jalopnik readers teamed up on two DLC packs for Forza Motorsport 3 and we're working with them for some similar team-ups for Forza Motorsport 4. We're not getting paid anything for this relationship. It's mostly just because we think the franchise is awesome.
