Edelbrock Heads for 318

The 318 is a great motor but low 11's in the quarter mile with no nitrous or supercharger ? Unless the car is superlight I do not see how that is poss. Maybe that the same track Car & Driver takes these new cars they claim are 12 second ones, ha ha. There are a few pro stock cars that can go 135 mph in the quarter but they are all running more than a carb. 318 on pure 87 octane gasoline. Those 302 heads might give as much as 75 horse more but still means 375-400 horse power at the very top and on 87 octane, boy I don't know, that must be some good stuff you are smoking. I believe to get a 3500 lbs car in the uper 10's which is also about a 135 mph speed you need like 550-600 HP.
