I'm trying to stuff a 383 in my 72 Nova with a 144 weiand blower and 1/2" Nitrous spray plate. I bought a goodmark 2" cowl and it its short by about 1/2". I don't want to go with a larger cowl, I hated to go to the 2" as it was. I did go with the 1 1/4" dropped air filter to get to this point which for some reason the opening in the cowl hood is about 1 1/2" to far forward. I'm thinking of going with the modular air intake system, they have a low profile hat, but either way I still end up with being short 1/2" (story of my life!) I think I remember that the bb motor mounts set the motor a little lower - is that true or do they make a lower mount? I have a strong 3/4" between my subframe and the oil pan so I have the room if I can find a way to drop it. Do anyone know how this modular air intake would work with the Weiand 144 Blower or am I wasting my time. I think this system stands the best chance of working with my dilema. Thank you in advance for your help. Rick

BBC mounts moved the motor UP, and to the left; to clear the steering box not down. The blower is the problem. Because it is a tiny roots system you can't run a remote carb (too much lag time, and too great a danger of a back fire). What you are looking for is a ProCharger style centripetal blow through system which would fit beneath a flat hood.

Also because it is a Roots style blower you need to have a boost referenced blower carburetor on top of the 144 or you will have problem with the idle hunting. It also needs to know how much manifold vacuum/boost to provide the correct fuel-air mixture.

Is that Up and to the Left or Down and to the Right,Right being Passenger Side?

I do have a referenced carb on there, as well my ignition box. Can i run the modular system and stick the air filter in front of the radiator support, or not a good idea. My big problem is the size of the air filter wont clear the hood. I have a 14" with 1 1/4" drop. It works against me to go with a smaller air filter because anthing smaller that a 14" means I have to give up the 1 1/4" drop which is a big help. Maybe I should just go back to the stock hood and cut it up or try to fit a good looking scoop which is exactly what I didn't want to do. O well, any help or suggestions would be a big help and thanks for the info on the BB mounts

Go with a forced air induction hat and plumb that into the front of your car with a filter on the end of the cold air hose.

BBC motor s moved up in the air an inch and a half and over an inch to the passenger side of the car to clear the steering gear box and the wiper motor. The heater core has the piping exiting in the middle of the cover instead of one end like on the SBC (to clear those big heads).

thanks Dave. i just found out one other thing. I have a Demon (Mighty Demon) carb. The reason I could not go down to a 2" element (which would work) is that the 2 tubes (what are these for?) that come out of the top of the carb hit the Air Cleaner cover. If I could trim these down 1/2" that would work too. I'm sure those tubes are that long for a reason but I thought i would throw anther dumb question out there. Thanks, Rick

Those are the bowl vents. They can be trimed but keep the angle to provide clean (undisturbed air flow).

Big Dave

Dave - the tubes are cut straight and thats the way they came. Should I cut them at an angle like I see some others? Also, can I remove them to cut, if so how. Thanks for all your help, Rick

On a Holley they can be pulled out with needle nose pliers (they are pressed in). Holley uses a 45 degree angle to get a smooth laminar air flow into the carb. The vents use the air flow over the top to equalize air pressure in the fuel bowls. This is of critical importance because a quarter of a pound per square inch differential can start fuel flowing out of the booster and into the motor.
