13B SP/BP and emissions

Why do you fail emissions when you have a BP engine? Because of the unburned A/F mixture?

Is there any way to temporary pass emissions?(Besides engine swap)

Maybe a CAT or Dual cats?! Or Thermal reactor with cat? Spark plug in the exhaust to burn the unburned A/F mixture?
I'm talking stupid I know.

I would just like to know if you can pass emissions temporary with a BP 12a or 13B.

ha ha ha. Bridgeport can't pass unless you cheat and/or spend lost/lots of cash trying. You'd be dealing with a 3000PPM+ of unburnt HC(simialer to a snowmobile at idle and thats not going to be absorbed by a small cat, and if you did manage to find a special cat big enough or put a few in parrellel, you'd need to get a air pump plumbed to each one to get it to work half proper. ...and man on man, that would throw off heat, those cats would be glowing the whole time!@!

I would recomend you Bit the bullet, put in a stock engine/cats and take it out afterwards LOL!
