What does my time slip tell you about the engine.
I found this in the bills. I think its the worst one to. This is when I had the LG4 in the firebird this summer fully computer controlled then only mods no cat and comp 270 H, Dont laugh at my R/T it was the first run of the year but I did win
.
Edit: 2:73 open rear and th200c.
R/T...1.047
60...2.571
330...6.897
1/8...10.451
MPH...68.74
1000...13.535
1/4...16.134
MPH...86.92
These were run @4800ft and thank *** not corrected.
Im trying to get a clear picture of what the engine was doing at the time, seems to me it was running strong.
Any imput would be great.

yes, sounds strong. You had pretty bad wheel spin that run, it killed your time. They say speed is the judge of HP, and with your speed, all you needed to do is get a good hook off the line and your time should have been around a 15.7 or so. - Randy

It seems it had around 215hp with minor mods, cam and no cat. Im trying to figure out if my guess is correct and that added 75hp over stock. It just seems a bit high to me.
