Randy you are going to have an awesome running car. You might be faster then me unless I can get back to the track sometime and try a few things. I think I have 10.50's in mine with more tuning and more carb but I dont know when I will get back to the track. I used the 4.15 crank for 493 cubes with 10.6 comp and I also use a Dwayne Porter speced flat tappet cam thats close to yours but a tad more. The 63 weighs just over 3700 with me in it. Your car ran great before so I wont be surprised to see you run 10.70's or better. Good luck my friend and keep us posted on that cool machines progress. Ron
