The only piece not sorted out on my 351 swap is the Trick Flow intake, p/n TFS 51500004. According to Summit it will handle an EGR set up. The TF web site says in a foot note the 351 intakes don't work with EGR systems but isn't part number specific so who knows? I have to stay legal all the way, in my county in CO it is a real !#@% when it comes to emissions testing every two years. Any help out there?
