I bought my first tunnel ram today and I'm excited as hell to get it on an saw a hole in my hood, but first I need carbs. I've been doing some searching and as far as I can tell there are two schools of thought as far as tunnel rams are concerned. School 1- Two small carbs- This school says that two 390 or 450 holleys will work best becuase of the combined flow. This school also tends to say that vacuum secondaries are best because the motor will only use as much fuel and air as it needs. School 2- Two big carbs- This school says that if it runs good with a single 600-750 carb, then it will run good with two. They say that it will make more power without any sacrifice in throttle responce. Some of them also say that mechanical secondaries work fine because it will give the motor as much fuel and air as it can take. The engine in my Comet is a stock bottom end 289, but the ultimate goal is a forged 331 stroker. Currently I've got a 600 edelbrock mechanical secondary carb on it. It has Edelbrock heads with 1.9/1.6 valves and the cam is 224/234 @.050, .496/.520 lift. It's backed by a T-5 and 4.11 gears turning 235/60-15 tires. It's set up as a street gasser and is stripped down quite a bit. I figure 2850 lbs with me in it. It is a street car and I drive it a lot. What are your thoughts? Would love to hear from the guys running a ram on the street.
