60 horses less than an LT1, probably add another second and change to the quarter mile. Call it 16.5 seconds in the low 80's.
0-60, probably at least a second slower than the LT1, call it 8.5 seconds.
If your rear gear is that high, might lose another couple of tenths on top of that.
No data to back it up, but I think my estimate is actually on the optimistic side.
