10 years ago,
A 1988 Mustang, threw out the 302 and dumped in a heavily modifeid 1969 351W with NOS. On the dyno it made 437HP at the wheels. It also had a 150HP NOS power shot. The car ran a best of 11:96@110 mph without the NOS and 10:92@121 with NOS on 2nd and 3rd gear.
The best part about this was, the car was my daily driver. All I did when I brought it to the drag strip was put on a set of DOT slicks on the rear. Ahhhhh those were the days, I sold it about 8-9 years ago, i still miss it
