That’s crazy. I have a 85 that has a cage an one race seat in it, no ac but still has power steering. I’m not sure the bottom end but from what I was told it’s a 306 with a cam and does have Windsor aluminum heads with a Holley intake with a 750 Holley carb with 373 gears and a tci c4 trans. To me I should be running faster then a 13.3. The last time I had it at the track it ran 13.3 @ 100.4 mph with a 1.9 60 foot.
