got stg2 cam for single zc tightened valves to service spec but car stumbles lick a subaru

car runs like pooo

 

check your firing order on the distributor and plug wires

 

lemme guess, your car is NA stock compression ratio.

 

all stock exept cam

 

There ya go, you're overcammed. You probably lost more power in the low-mid range than you gained on the top end. If you gained anything at all.
There's more to building an engine that makes usable power than buying everything that says "stage2" on it.

 

very well put

 

Were stock specs the recommendation of the cam manufacturer?

I agree with klyph

 

I'm going to guess the engine isn't in time.

Post your cam card, homeslice.
