Need info from anyone across the pond re emissions....First ; how does your HC and CO limit compare to my need to be max of 220ppm HC and 1.2% CO at idle and 2500 rpm then back to idle. Have any of you Britts passed your MOT emissions test w/ better or no worse limits than I need to meet with a carbed engine and if so did you need cats??? I'd love to hear from someone who passed my type limits w/ a 427FE carbed block and also a 427 and or 408 Windsor Fuel injected block.......Any details re engine cam profiles, compression heads and carb w/b a big help as well as description of cat or cats if used ect THANKS Steve
