    Ran my new combo for the 1st time today

    13.565 at 104mph 2.00 60 foot time. Ran the Nitto Extremes 255/40/17s. I am sure the times would be better with some MT ET street radials.

    Congrats, with a little practice and seat time you will easily be in the mid 12's

    Not bad for the 1st. time out! I'd have to say 42's might be a little bit for your combo. But anyway, your combo is easily capable of a mid to low 12.
    Good luck!!

    Why dont you post up the details of your whole slip.

    I ran at Quaker City - track rental day thru Cruizin Few car club. I was shifting at 5500rpm. I definetely need more practice - I missed the 1 to 2 shift and the 2 to 3 shift on 3 of my passes. Not sure if the synchros are gone or just my technique that is bad. The car felt like it was running out of power in 3rd gear at 2/3 track.

    Here is my slip:
    RT .715
    60 2.000
    330 5.779
    1/8 8.799
    MPH 82.90
    1000 11.331
    1/4 13.565
    MPH 104.48

    I think your throttle body may be a little small for the heads, cam and especially the intake you are running.

    Can you post a picture of your dyno graph? At what RPM did it make peak HP and TQ? There should definitely be more in it which is a good thing! :)

    Id say you also need 4.10's and some drag radials or slicks then the 12's will come!

    That is a very low powerband, do you have your cam retarded?
    Id figure whith your combo it would pull to 6000-6500 no problem. Somethings up, we just got to figure out what it is. Do you have an aftermarket ignition box? Problem could be there.....

    Yea I kinda thought that it would pull alot higher than that too, but its hard to diagnose something like this over the innanets.

    the cam was installed straight up(not degreed) and...

    I am running the stock TFI ignition, stock distributor and stock 94 fuel rails. My tuner(Don Lasota) told me the stock stuff was good up to 500RWHP, so I kept them. Anyone know how to diagnose the ignition? Perhaps it is falling on its face. The car does have a problem restarting when it is hot. Sometimes I have to wait 10 minutes before it will restart.
    Thanks for your input.

    A buddy of mine had the same problem with his 95. Never did figure it out before he got rid of the car. I'd be curious to know what causes that.

    Possibly the ignition stator??? Mine went bad in my car, and my problem was very similar to your's.
