what should i gap my spark plugs to for this setup and what ones should i get too is hollowing out my cat a good idea please some body let me know

 

Since your engine is mainly stock with bolt-ons, I'd use a stock gap or close it down .05" and see if it likes it on the dyno.

 

what you mean i already dynoed it and it and i didnt gap the spark plugs before that i just put them in straight fromthe box so should i just gap it to .05 also my car is backfiring and misfiring i think it is my rotor and spark plugs because the wires i just purchased and i only had the msd for about a year so yeah thanks for the help

 

do you think hollowing out my cat is good idea to make a little more power and be less restrictive to my motor to

 

No, it will make little if any difference you that engine and will only hurt the environment.


You adjust the gap while tuning on the dyno to see how the car reacts. You don't close it down to .05" , you close it down by that amount. If it makes more power by closing the gap down a little, great, if not leave it stock. Check your firing order and make sure your plug wires are all installed properly and in the correct order, after that check your cap and rotor.
