Ran the R/T today at the season opening test and tune, I got there late and lines were long. I did get 2 passes in, first pass was 12.79 @107mph 1.90 60ft second pass was 12.51@108mph 1.94 60ft. I cut 2 10ths from last year by removing the 2 inch spacer. It seams as though the shorter duration cam I have now doesn't need the extra plenum volume. With the solid purple shaft it ran 12. 20s n 30s with the spacer and 12.50s without the spacer. I tried to post a link to my facebook page but don't think I did it right.

I tried it on my phone and I chose the face book icon and it did go to it. I don't know how it works on a computer as I always use my phone.

Yes Budnicks it did slow down. I went from the mopar 296 557 solid flat tapet to a 270/280 586 solid roller. Only the 4th time down the track with this cam, and think there is more with tuning. Tires are 10+ years old at least and I'm planing on new tires this year. Possibly 4.10 gears too.
