i'm hoping this setup will put me around 330+ hp/330+ tq with a 29.5" tire and 4.10s. anything i'm forgetting?

 

Looks good. Which oil pump are you going to use, the stock one? It is recommended to use the Red o-ring, part 12584922 unless the oil pump manufacturer specifies otherwise.

Also, I could save you some cash by telling you that FTI has a street brawler 278mm 3200rpm converter for $309 at jegs, or a 3000rpm for $299.

you guys wont believe this. i've been planning a camshaft since i got this engine about a year ago, and my dad was all for it. i was going to pay for EVERYTHING that i listed myself. i just sold my dirtbike to pay for this. i didn't want to sell it (which i also payed for myself) but i wanted a cam more than i wanted the bike. they decide i'm not responsible enough and wont allow me to get a cam. the one thing i actually enjoy and excel at they wont allow it. sorry guys it's out of my control. maybe this thread could be a petition for them to change their mind lol
