what kind of power on 355 can you expect from a n/a tpi unit, with changes like accel runners and ported plenum, new intake, 52 throttle body, 22# inj, the 355 would be a zz4 with fast burn heads and a lt4 hotcam package would the tpi be able to support this and power outputs????

 

a TPI intake will not support the upper rpms of the hotcam

your best bet is to get some dart heads and have a LT1 intake mated to it

 

Or you can get a cam that will work with the TPI's power range.
