simple 360 ET update

Should be in the 11's with the MPH, like 11.80's or so. If it's not 60' in the low 1.7 or better into the 1.6 range, you should start looking there.

Don't know what air pressure you run in the rears, but, if MT et radials, don't get sucked into lowering the pressures if at 16psi. Most of the cars like more pressure, like up around 20psi.

Clamp the crap out of the front section of your rear springs. Make them rigid!

Have fun!
