Holy crow guys!!.I am almost embarrass to have built a 383.Is this BBC month??.

Pat,Richard and me did a on line dyno build sheet on what is a peanut 383 to come up with 480 lbs of torque at only 3500 RPM.And Pat commented that could reach alittle over 500 lbs if I wanted to really get after it.Certainly well over 400 lbs off idle.Those are respectable numbers guys without the gas penalty of a BBC.

Once done,I fully intend to put a tune on it to get high teens-lower twenties in gas mileage.

In terms of headers-I totally agree with what you guys posted.
