im looking to get a cam for my Formula 350 but im not sure what to get. ive read the tpi systems dont like to breath so something with a high duration is out of the question right? whats the most aggressive cam you guys would suggest for this engine while keeping the rest of the internals stock. my final goal for the engine is about 300-320 hp (maybe more) and i already have a custom chip on order.

 

anyone?

 

I think you should be asking this in the TPI sub-forum, but I remember that GMHTP magazine's project SOSN made 416 HP at 5000 rpm with a Comp 210/220-114 cam. But that was with ported Vortec heads.
