10ZZZZ??
I don't see mention in your post as to what, if any, you have done to the suspension. I'd also be wondering about 28" tires.[3.70 gear?]
Do you have a trans brake? If not, then the rear brakes will have to be up to holding considerable boost in order to get the short times others are mentioning.
Not hitting the mentioned 1.5 short time will make it VERY difficult to get the 10's you are looking to get, especially w/ a car that's near 3600#.
Here's a bit of data that has been gathered from 1000's of runs.
IF ALL segments of the run are made as follows, the resulting ET is then possible.
60'= 1.49, 330'=4.45, 660'=6.98, 1320'= 11.00@121mph
" 1.46, " 4.36, " 6.81, " 10.75@123.5 mph
You can interpolate and see where you will have to be during the various points on the track to get your 10 time slip.
I'd go to work getting the car to 60' and run some 1/8th runs B4 I leaned on the motor for a full qtr. This will save some wear/tear on the car and allow you to see if the goal is attainable without joining the "DOTC " club!!
Notice how a reduction of .003 in 60' results in a reduction at 1320' of .250!!
HTH,
