I am ordering my Roush 427SR with Fuel Injection, it is built off (bored and stroked from) a 351W. Factory Five is saying the Performer RPM intake is too high and will not clear the hood. They are recommending are saying a Performer intake will clear. EFI should give more clearance than a carburetor...

Does anyone have any experience fitting a 351 under the hood and what intake and air cleaner did you use?

I do not want to alter the hood.
