Need help/suggestions with my lt4 i have a 97 camaro with a an original lt1 block but has lt4 heads, throttle body, and injectors...tranny is just a ws6 rebuild, the motor is balanced and blue printed, bored 30over, it has an lt4 cam/lt4 kit, ported and polished cast heads.... the camaro is throwing a few codes and i beleive they are all related to one issue. the codes are (P0420 catalyst system efficiency below threshold-Bank 1) (P0336 cranksfat position sensor A circuit range/performance) (P0335 Crankshaft position sensor A circuit) (P1371 ICM 4x reference too few pulses). the car fires RIGHT up and drives fine but i feel a lack of power. this camaro dynoed @400HP (SUPPOSEDLY)and i dont feel 400HP at all. fropm researching online im thinking its the opti and thats whay a shop said when i called them as well

Why are you starting another thread when you already have one going in the lt1 section with the same questions?

We're trying to help you there, you just did not give us enough info in the first post.
