1.45, 4.272, 6.626 . The vert may be a tad on the tight side, but if the engine made more power it would make up the difference and stall higher.
I don't like harping on this, but here's some data that should put some perspective on how out of sync something is w/ your combination.
This was a 10.7 CR RB 452 w/ 305 (
not a misprint) CFM Stage VI heads, 266 at .050 x .600 x 108 solid flat-tappet cam, and a small 1.42 venturi x 1.75 throttle 4150 carb on a standard Victor intake.
Engine made ~ 610 HP peak at 6300; ~ 570 torque peak at 4900
E-body aerodynamics... not great.
4200 stall / 4500-flash 9.5 converter; 8% slippage
4.10s; M/T ET Street 275/60R15s w/ loaded radius of ~ 13.7"
Best pass launching from approx 2200 RPM, 1-2 shift at 6300, 2-3 shift at 6500, trap RPM 6800+:
60' - 1.454
330 - 4.254
660' - 6.653 at 102.03
1000' - 8.745
1320' - 10.523 at 126.44
Track digital scale showed 3755#s w/ driver right after this pass.
Track elevation is 80'; weather conditions for that run were 63*, 70% humidity, 30.05" barometric pressure.
No, It's NOT an apples-to-apples comparison w/ your results. But your 60/330/660 times aren't much different than mine. Mine ran out of steam on the big end, though.
Here's another long thread from a couple years ago that's also NOT apples-to-apples w/ what we're talking about, but still might be of interest:
