Another way to figure it, is that going from an 11 to 10 tooth sprocket, you will only go 10/11 as fast, or a loss of about 10% of top speed. This is assuming the motor makes the power for a full shift-out of the auto. So, if you went, maybe 45 before, you will only do about 40 or so (in round numbers).
However, don't think you could go to a 15 tooth front or anything like that, and be able to go 15/11 as fast, or over 60 MPH because I don't think that a 325 engine makes enough power to get the machine to go that fast.


I agree, though, that if you are willing to spend a few extra $$, get a clutch kit, and you should be able to get more pulling power with little or no loss of top speed.
