Yes, but what SVT LIM are you comparing it too. The early LIM are just a stock LIM bored out ~2mm.

The late model SVT/returnless LIM is actually a different casting. It's around 4-7mm larger then either the early SVT or stock respectively as is.


LIM are classified by the inlet port diameter. They all taper to a smaller outlet port.

Something else you need to be aware of is the SVT's had the head inlet ports EH'd to open them up. (98/98.5 single - secondary & 99/00 dual - both ports)
Adding a larger LIM to an older SVT or especially any non-SVT will create a lip protruding into the airflow! Very bad for performance.

Also all head ports have a fair amount of machining flash that lips into the airflow too. A must to remove.

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
