[QUOTE="Blackgeetee, post: 50216, member: 1684"] [b]yes, '98's SUCK![/b] The difference in ET's are about a full second in the quarter. The stock '98's run about 15 flat, whereas the '99+ run 14 flat roughly. For '99, Ford decided to pull their collective heads out of their asses and redo the heads. The pre 99's heads were relatively restrictive. Just changing the heads and the lower intake made one heck of a difference. For only around a grand, one can swap in 99 heads and drop off a second in the quarter. When I just had the cat-back on, I ran a 9.5 1/8th at 78mph, and 14.8 @93mph in the quarter. I still haven't taken it to the strip since I removed all the cats, but I can feel a big difference in power above 3000rpm. Last week the g-tech said I had a trap speed of 98.5 mph. But the ET was only 14.7. I had traction problems so I think I could run below 14.5 now. We'll see. Hillie, you need to get to the track and let us know how she runs!:D [/QUOTE]
