No, it's still a 97" wheelbase just like the street AMX. AMC / Hurst didn't build these cars too awfully special. You got the engine with 12.5:1 Jahns pistons, Crane ported heads, a stock .425" lift street cam and the Edelbrock STR intake with two #4858 (585 CFM) Holly carbs, Mallory distributor, Dougs headers. You buy it, you blueprint it.
The trans was a 2.64 low T-10 with Hurst linkage and modified floor for the linkage.
Rear was the Model 20 by Dana with 4.44:1 ratio and aftermarket 1-piece axles.
The engine (other than the cam, AMC expected you to put your own roller grind in) was decent.
But there wasn't anything really special about the body other than the loss of sound deadner, hood scoop, battery in trunk. Nothing like the Hurst '68 Mopar's with fiberglass front end, light weight glass, seats, etc.
But they sure did run and still do today. Right now I see the SS/C record is held by Aris Asdourian's SS/AMX in the 9-teens. AH Adkins runs about the same but in SS/B. The 8's are a real possibility for a SS/B AMX.
Now aren't you glad you asked?
