I'll take a guess at your fwhp to be 690, if your chassis is up to it and its all running on song your ticket could look something like this with the tyre height@28"?+3.7's>
60 Foot E.T. : 1.35
1/8 Mile E.T. : 6.15
1/8 Mile Trap Speed : 110.61
1/4 Mile E.T. : 9.74
1/4 Mile Trap Speed : 138
1/4 Mile Trap RPM : 6,114+slip
1969 'Cuda 446ci, best 9.96@133.9 in 1990
1971 340 'Cuda, best 11.01@122.8 in 1987

if the weight is with the driver it should run 9.80 at 137.+ MPH once sorted out with open headers  My old pump gas Duster ran 9.993 at 134.8 MPH corked up(3.0 inch exhaust system to the rear bumper) on pump swill with a 518 C.I. 400 block stroker motor with a little less compression weighing 3450 lbs. with me in it. IHTHs  Good luck, let us know what it does

Weight is with driver. 2in fenderwell headers into 3.5in exhaust straight through mufflers dumped in front of rear tires. Would be great if it went a 10.0 N/A

I have a similar 512 combination. My 69 Dart is 3500 pounds with Driver. Indy EZ heads opened to max wedge size ,Indy intake ,1050 , one of Dwayne’s solid rollers 268/270 duration 646/646 lift,11.2 to1 compression,Ultimate 9 1/2 converter. The car has Caltracs and 410 Ratio with 10.5 x 29.5x 15 radials. Yesterday it ran 9.86 trough the mufflers at 134.I think it would probably do 9.70 uncorked with a little tweaking, but its time to slow it down a bit.

Would be great if it went a 10.0 N/A high 9.80's..should do it easy with good hook/60..... As a comparison which is not even close, my mates '69 Dart, 3180, 446ci/12.7/eddy 320cfm heads/.590 purple solid/victor int/950 DP/4.56/13x31's/SS springs/5000 stall, trap@6700, 10.1's@132+..599fwhp
