As a fellow owner of both car and mechanic the GTP WILL get the aurora on the top end but the olds v-8 gets the gtp out of the hole, I've raced them both. both vehicles can be modded but you'll find the GTP has more potential with its EATON GEN 3 SC. The GTP does put out more torque by 20ft.lbs but 10 less HP 240 compared to 250. Anyway hope this helps!
about 240
yes i have them on my car
