That is one very sweet Mopar. And of course I love the early B's. You did fine for the first time out. But I agree your car should be able to run 11's with ease when you get everything in tune. My 63 's 440 makes about 500 flywheel hp and at 3700 lbs has hit 11.50's @ 116 and I think we can help you go faster then me. I use 906 heads I ported and have the MP solid .557 cam. I usually shift about 6200 by my tach but to be honest I shift by the feel of the eng and it is about 6200 when it feels like it's time to shift. I trap about 6300 to 6400 using 4.30's with 30 x 9 Hoosier radial slicks. My best 60 this year has been a 1.59 and I usually 60 in the low 1.60's. I feel your car should be in the 1.60's with no trouble for the 60's. I just use SS springs and long shocks in the rear with stock front suspension and I just added the Comp 90/10 shocks a few weeks ago. I believe your eng and combo should go 115. The mph is a could figure of power it is making and at 108 you wont go 11's but with good hook low 12's can be had at 108. So we need to see where your loosing some power and get the hook working as it should hook hard. I use a Dynamic 9.5 that flashes about 4200 and on a good track it will hook like glue. Dont worry you will get it and you still ran very good for the first outing in that sweet 64. Ron
