Default 87 performance sound right

My times, with street tires, factory convertor and 2.73 gears were a best 1/8 mile run was 8.471 @ 83.98 mph with a 2.044 60' time and a 5.581 330' time back on 2-26-05, last time I ran at the track. On a local Dynojet chassis dyno on 2-19-05 it dynoed at 254.3 HP and 331.7 torque, I thought it would make more power and go a little quicker but that is what I got.
My car is an 87 automatic convertible with stock 113 heads, TPIS ZZ9 cam, TPIS Big Mouth intake, AS&M semi-siamised runners, Comp Cams 1.5 Pro Magnum roller rockers, SVO 24lb flow matched injectors, and true dual 2 1/2" exhaust off factory headers with Flowmaster mufflers, and a chip by skidownit (Jessie).

Do these times sound right or am I missing power somewhere?

Those are good numbers. The intake is costing you about .2. A Miniram would get hat for you.

How much do you think a 2400 stall lock up converter would help?

Mostly just get tirespin unless you get some drag radials.
