ok what track times does the lt4 get?

and is the hot cam the best for the lt4 or does it have a better bigger one?

im looking at emissions too so.

 

Haven't had it to the track yet, but dyno numbers are in my sig. This is with the stock LT4 cam, so figure another 25-30HP with the Hotcam. The LT4 is very emissions friendly, even with the Hotcam. As far as times, Car Craft got a 13.2@107 out of a 97 LT4 SS, which would have been a 280RWHP car since all the LT4 SS/Firehawk cars used the stock LT1 tuning from the factory (ever one I've seen dynoed did right at 280RWHP stock and 300RWHP with tuning). So I'd say low 13s, possibly even high 12s for an LT4 f-body, and definitely into the 12s with the LT4 w/Hotcam.

 

107mph is good for 12s too... look at my times
