I was close in my estimate because I know this cam. Do you have a picture of the dyno sheet? That way I can see your power curve, and a/f ratio.
Your motor has a lot left to gain with this cam/head combo. I would say with LT's ORY and 3'' open exhaust with a good live 93 tune you will see 365whp 345wtq. Like I said before this cam is all about the exhaust. Also make your shift points at about 6500rpms. It will be much happier there.
look for low 13's to mid 12's on th track.
