Clutch slippage! Noooo

[Bubbas Garage]

Well, just got done doing a trans swap ( auto to manual) Supposedly the manual is a shep stage 3 with short shifter ( no way knowing unless i take it apart) and act 2600 cltuch.. Anyway, just got it running better so i went and drove it for the first time. romped on it a couple times... then i seen a buddy in a duramax so i went and got next to him and showed him ### it had.... untill my clutch slipped like a mother***** and looked back and seen a nice cloud of white :/. So were gonna look at it tonight and make sure its all adjusted right tonight. But, if not... What size clutch you guys think i should go with? Plans for the car are just weekend street car, take it to the dragstrip every once in a while. Id estimate the car to have 400-450 hp. But, would like a clutch thats good to 500 since i may up the boost in the futer. heres my mods

Thanks for the reply, at this point im mainly wondering if you think it could just be improperly adjusted or is it just not a big enough clutch?
