The gas smell comes from long duration cams using a carburettor.

The bigger the cam, the worse the smell is.

Sequential EFI will eliminate the smell.

If your system is sequential, get hold of a decent tuner to sort it.

Having said that, my mates 355 makes more outright power with a Quick Fuel 750 DP than it did with a dyno tuned group fired EFI system, 4 barrel throttle body etc.
