Wait, so you think improving my 60' down to 1.7-1.9 wont improve my time? The MPH is good for 13.20s. Also, I reviewed my logs from the track and the PCM was pulling timing because my ECT was 203-212 during the runs. I only had 21-22 degrees of timing. I need to get my Efans on high in the staging lanes. At the track I saw a best of 416 lb/ft of delivered engine torque. My best on the street with more timing and a cooler engine is 438 lb/ft.

I don't see it happening honestly. I say 13.5 max with your current setup. A cam would help a ton considering the converter you're running

considering the low timing, heat soak, and lack of track time, i say you might be able to squeeze a few 1/10ths out of it the way it sits... BTw do you have a cutout?

No cutout sir, just to stock catback.

Cam swap is underway as we speak.

NICE, what cam did you go with? also you should look into a cutout, since your running that stock cat back, it alone should drop you a .1-.2....

Congrats! Like Black said, what cam are you going with?

Just a baby EPS cam. Mid 220s 600" lift. I should be going to a 3.5" catback and a 3.5" cutout. BTW, no attempt was made to catch any coolant....let's just say we now have a little river outside. lol.



(Just making sure this isn't really a 5.3)
