Proibe Could you give more info on the motor? Compression,heads and work done to them, Bore and stroke. What side pipes are you running? with or without mufflers? This is a large cam for a 427SO. Put this in a 484 motor and with the added cubes, it's streetable. Not sure how well the webers will run with this cam. If you are keeping the RPM under 6,500 rpm, go with a hydro roller lifter. You will need to change the Distributor gear also depending on the gear on the cam. I have a 484 with the small hydro roller from crane. Idle is a little loping and strong flat torque range for 2,500-6,200 rpm. Will have the numbers next week after the FI system gets the final dial in. Real numbers guess, at the crank 580ft tork and 490 hp. Figure there is about 10-20 hp sitting on the table before the final tuneup is done. There is a weber book that you might want to buy at Summit before you do the cam thing. I would find out who is running weber's and what cam they have. I do know that the 48mm webers runout of air at 6,800 rpm. With the right cam, midrange you pickup from 15-30hp over a carb, and they look great. You will need to buy extra jets,tubes, and possible chokes for them. You might want to look into a FI system like TWM. Look like webers but with FI run better when setup right. I have a set going on my 496 motor of 58mm TWM's. I am not a weber pro but there is something about cam overlap or dual patterns that they don't respond well to. Try the FE forum for more info.
