Rate my HP

Hello all. I was just wondering if someone could give me an idea of what my horsepower may be with my minimal mods (shown below). I know it's not incredible, but I'm just trying to get an idea of what I'm working with. I'm also wondering what my next mod should be? I'm assuming it's headers, but I've been wrong before!

------------------
91 TA 5.7 TPI Automatic.
w/WS6 and 3.23 rear.
K&N Air Filter,Hypertech Coil,Moroso Blue Max Wires, Bosch Platinum plugs gapped at .050,
JET fan switch,JET air foil,Dual cats with Flowmaster 3" exhaust (Headers coming soon),
Complete PST components on front suspension, Spohn LCAs/Panhard bar.
It's not much, but it's a start and I have a Summit catalog! :-)

roughly.

well considering he started with 245.. i'd say the only mods that have given you some hp are the exhaust and the k&n may have done something.. i'd say about 250 something.. i think the headers will help out, thoughta bout doing some intake work? porting and what have you.. i bet that would work pretty well, especially along with a nice exhaust..on another note, how do you like the LCA's and panhard bar? much difference?

It helped a bunch. With stock, my car shimmied around every damn corner. It's stiffer now and to quote others here...it just feels more "connected".
