And gas was 30 cents a gallon. Life is about making compromises. I ran 391's when I first got my Dart and couldn't stand the car on the highway. I could literally watch the gas gauge drop while the engine roared. No fun at all. I switched out the pumpkin to 323's and got better gas mileage and highway cruising, but lost the stop light fun factor. I think the 355's will be a good compromise, and the torque of the 408 will help get the car moving. JMHO
