i still say a trip to a local dyno would shed a good bit of light on the subject here, that and getting rid of some nameless people who dont know what they are talking about would help too. another thing i just thought of is you catyltic converter. a clogged one will cripple an engine. a suggestion would be to get a new cat and go with something like a catco hi flowing unit, gut the stock one yourself (take the cat out, and ram a nice size rod through it until the guts are gone, then stick a pipe through the middle the same size as your exhaust) or buy a mac off road pipe. be warned, if you have a sniffer test in your area, the last two options are basically ruled out. if its only visual then you can get away with the gutted cat because it looks like its still there.

run a can of seafoam through your engine. i did that with my 87 v6 camaro and it came to life. for what its worth the car had about 170k on it when i did that. you can pick it up at a local aauto parts store. runs about 7.50 with tax.

another thing could be added weight. have you added any stereo equipment to your car? i.e. a subwoofer box and amps in the back?

one last thing and i know you probably already thought of this but is your car a real L98? if you car is running good, then you are posting what a good running 305 TPI will run. check the VIN, the eighth number should be an 8. that will tell you for sure.

hope any of this helps.

Thanks for the input guys. Sounds like I should be running a bit quicker with my current setup. Also sounds like the valve springs may be part of the issue.

Also just to clear up some of the questions, here's a complete list of what I know has been done to the car.

The car is or at least was an L98 car...but for all I know it could have had a 305 swapped into it at some point in its life, but I doubt it.

K&N Cone A/F installed in the stock airfilter box location.
MAF screens removed
JET Products Airfoil
MSD 8mm Plug Wires
Accel Super Coil
Generic 1.6 roller tip rocker arms
SLP Runners
Minor port matching of the plenum to the Runners
Removed EGR wall just inside plenum
BBK AFPR set to 48 PSI w/vaccum line pulled (50PSI didn't make a noticable difference at the track and stock was 44PSI)
3.27 rearend
Hooker Super Comp Shorty Headers
Flowmaster Cat Back Exhaust
Flowmaster Muffler
Single Catco Hi Flow 3" Catalytic converter (BRAND NEW, long story as to how I got from dual cats to a single)
Dunlap SP5000's
Recently tuned up and timing set to 10 degrees advanced.
Unknown aftermarket chip (was in car when I bought it and is simply marked For Offroad Use Only)


Thats about all I can think of right now. I'll keep playing with the setup to see if I can eek a few more tenths out of this combination, but it seems that if the motor is healthy, I should be running mid to low 14's. Also for those who talked about heads/cam etc, I'm not planning on that for the time being and may actually sell the car before spending that kind of money on it.

To those that posted intelligent and helpful responses, thanks.
