I have a 482 Pond from Keith with a ported Blue Thunder intake and ported edlebrock heads. I started with a 850 Mighty Demon (carb sucked
). Went to an 830 Holley. Still rich for driving conditions and street use. Then I got a Bigs 750HP. Much better. Most people do not consider driving style and what you are going to be using the car for. If your plan is to drag race the cobra then go with a 950 DP. If you plan to go open track the Cobra then get a blue printed 750 HP.
