I appreciate the input but I already have a motor and trans to put in the car. My 408 SBC and glide. I run s/st on the 10.90 index and the turbo isnt consistent enough. If my 60 foot varies .003 its a bad day. I was 1.880 - 1.882 over 6 rounds yesterday on the throttle stop. It will 60 in the 1.42 - 1.44 range when I run it all out.
