I figure my car has at least 360 gross hp then. Considering it was rated at 250 stock with a 2-bbl carb/intake. On all my estimates I'm going low on, so I don't get my hopes up then get them shoved in my face. Start with 250+15(exhaust), 265+40(750 cfm carb), 305+20(intake), 325+30(cam)=355. And I figure an increase of 30 hp for the cam is very low. It's probably closer to 40-45. Which then it's 370 gross hp. That may be a little much. So I'll just use 360. So, 80% of 360 is 288. 75% of 288 is 216, and 80% of 288 is 230. So I probably have about 220-225 rwhp? At the most is probably 225-230, using 370 gross hp? I guess that's not as good as I thought, but it is a lot better than it could have been. So my car weighing 3200-3300 pounds and having 220-225 rwhp...is that good for low to mid 14s? Thanks for all the help everyone.

Rev, so you have about 230-235 rwhp right? And you hit 13.97@100.3. So it's definitely possible to get into the 13s for me with what I have right now. I just need small things. How did you have your car set up suspension-wise and how was the weather? And what elevation? What gears do you have, and how were your 60' times? I feel like I'm about 6 right now because I'm asking so many questions. So I'll just stop for this post. Thanks Rev, and everyone else who has replied.
