Make sure you inform the converter manufacturer of the weight. If they
assume a 3200 lb Mustang, you'll get a lower stall in your lighter roadster.

The X303 cam will likely not make power to 6800+RPM. Due to the heavy
hydraulic roller lifters, you may have peak power at 6000 RPM. The
Crane roller lifters have better tolerances and will extend your RPM
but they are relatively expensive. Anderson Ford Motorsport has done
a lot of work on hydraulic roller cams with OEM hydraulic roller lifters
and has cams that will support your RPM goals with stock lifters.
If you stay with a hydraulic roller cam and carb, make sure you use a
distributor with a steel Ford distributor gear that fits the shaft.
The later EFI distributors had the right gear but have a larger shaft.
The earlier carb distributors have an iron gear that's not compatible
with your roller cam but the carb distributors require a different
diameter (ID) gear. Ford Motorsport should have what you need.

The Edelbrock Victor Jr. is likely a better intake for your planned
RPM range. If you stick with the X303 cam, one of the better dual planes
might be better. The best dual plane for the SBF is probably the C90X
FoMoCo intake. It was designed by Ford and marketed through the Muscle
Parts program for the 351W head conversion package. The C90X is a rare
piece but the Edelbrock Air Gap and Edelbrock Performer RPM are also
good, as are the FoMoCo Shelby lettered and FoMoCo Cobra lettered intakes.

The stock 5.0L heads are the weak link in the build. If you have to pay for
shop labor and the heads need work (valve job, guides, etc.), you might
consider the Ford Motorsport GT40 turbo swirl aluminum heads.
www.buyfordmotorsport.com had them on sale last month for $699/
pr but I just
looked and they are back up to $375 each this month. Sometimes you can get
them on Ebay for $699/
pr. That's a fully assembled price with valve springs
that are compatible with your X303 cam.
