if you are one of the fortunate ones that live in an area that do not have to have emissions tests, then do not worry about reinstalling a cat converter when you do the engine swap. it goes by year of the car chassis, not the year of the engine, anyway. if you have a 88 camaro, let's say, and you put a engine out of a 68 camaro in it, then it has to meet emissions requirements of a 88 model year car, with all of the emissions controls devices that the 88 camaro came on it new. they all have to be at least on there and at least visually functioning. by that i mean it cannot be obviously disconnected or modified; stock appearing would best describe them. a 350 did not come stock in a 68 camaro anyway.

Alex! More information is helpful. What is the engine going into? Is there a benifit to taking off the cat? There is a little benefit if it is an OEM cat. Most of the aftermarket cats flow so much better and weigh so much less than the OEM, it is not worth removing an aftermarket cat. If you have the OEM cat, get a hi-flow cat installed and save yourself the possible $500 to $1000 fine. If you are putting the engine in a '68 camaro, then you don't need a cat.

It isn't the county that you should worry about. It is a FEDERAL crime to modify, remove or otherwise defeat ANY emissions component.
This sort of thing can give the local constabulary entre to further inspect your vehicle.
As far as performance, it depends on what powertrain management you have.
It CAN help some, if there is a CAM or ported heads, or if carburetion is the fuel metering devise. It CAN allow a bit more flow, but I haven't seen or known anyone over the last 25 or so years who has taken one off of a standard street machine who has seen any real appreciable increase in performance.
That isn't to say that a very well built rod won't see a difference, they will.
Good Luck
