Way back when my car was a stock 350 and i put that kit on it,I went from a 14.5 to a 13.2,,,,if that helps....currently running 12.9 on engine..11.8 on modified NOS system.

 

Just to let you know,i have the TPI plate system on my 91. Its a 305,only mods at the last time out were a flowmaster,drag radials,LOTS of removed wieght,and it ran a best of 12.38@108. On motor it went 13.44@101. This year im shooting for 11's with 3.73's and headers,and MORE nitrous

I bought a brand new system and had a hell of a time with it. I think it was defective. I run a digital 6 msd and it cant keep the spark under my cylinder pressures

87mph in the eigth. That is pretty fast I held it down through the quarter and sometimes it would only run 100!!! I never figured it out??
