like shwan said there all the same, cause the pi heads are all the same, it would only matter with 96-98 heads
Wrong, PI heads were on both Windsor and Romeo motors. Actually they were on the Winsor motors first. The Windsor plant ssupplies mostly engines for the truck lines but they were used exclusively in the '99-'00 mustangs. I was under the impression that all '02 and up Mustangs were Romeos until I rececntly saw an '03 I believe with a Windsor in it. Like I said, it should be a Romeo, but I'd make sure before you order anything.
