well i dont realy know if the engine is a "true" pro stock engine, i bought the car with the engine package, and they have just used it for bracket racing, but i have dyno that says 865hp with 1.6 ratio arm rockers and it should make 940 with the 1.7 and 1.8, i know the compression is 15.8, and your right about the detonation, but i was hoping that some timing retard and change cam duration, could make it run with a small amount of spray. I have orderd a o2 sensor kit, so maybe that could help me tune it up. thanks for your replies.....
