I have been having a hard time to register my car and pass the stupid inspection which is mandatory where I live...
The engine is 350 which is built as a 383 stroker with long tube headers. In order to pass the emission test, I had to put a catalytic converter on each side. The converters were taken off from a mustang, apparently from a newer model as per the muffler shop guy.
I also had to just adjust the air-fuel ratio in order to lower the CO and HC rates. Last but by no means least, I have flowmasters on each side, and I had to adjust the RPM in order to make it sound more quiet at idling. AT idling, the RPM is at 520 or sometimes less.
Sorry for the long story, but I had to go through all that crap in order to pass the emission test..
My concern is this:
If I keep the catalytic converters on, will it affect the engine as far as the higher back pressure goes.
I appreciate sharing your knowledge with me guys..
