There is not that much to gain with this new stuff. The factory part are really good. We spent over 14 grand on the new motor with all kinds od stocker tricks and picked up 12-15 HP over the old mostly stock stuff wich made 440 HP.

So then around 300 would be a fair number, I guess I wasn't too far off.

You say my motor is soft, it makes almost exactly 1.5 hp/rated hp. Assuming you're telling me the truth, you're about 43 rated hp away from that number.

Just curious, how many different cams have you guys tried, I'm sure there is a lot to be found there considering there haven't been many overhead cam stockers out there until the last couple years.

andie, who won C/SA and D/SA at Indy this year?

A 352 mustang red lit in the final of D, and Bryan Phillips won (super happy to see that). Kyle Ratcliff, who has one of the fastest LT1s in the country, won C, the new 302 in that class didn't run worth a crap (a 1.46 60' won't get it done). Did you notice what happened in E and F?

By the way, I go by Andrew, thanks.
