I removed the first disk as you said in your e-mail dated 4/24/01. This is on my 302 Engine, as I said before with the full insert I lost almost a half second and of course MPH. Yesterday was the first time we got to run because of rain. The first pass after I re-jetted carb. And new plugs was a 12.53 at 106 MPH. This was at noon. The next pass at 2:13 in the afternoon at about 65 degrees was 12.52 at 106 MPH. The next one was at 3:53 in the afternoon same temp. 12.61 at 106 MPH. The last one was a 12.57 at 106 MPH. So you can see I have got my ½ second back. I cut one disk and about an inch and a half of the front that faces the header tubes and put my extension back on (18” extension) and read my decibel meter at 50’ at 3500 RPM and it read 93db the same as my Capri with Flowmasters. We are going to remove one disk from my sons 460 as it reads 90db. Big blocks are not as noisy anyway. Thanks for your time on this. Hope this helps you some. ~Robert P
