Pulled the trigger (or rather emptied my account) and ordered Promaxx 175 heads, new 600 cfm FST carb, Edelbrock Performer RPM manifold, Scorpion roller rockers and a Crower Cam ( 218/224, .468/.486, 114 LSA for low and mid-range torque). Still need more "incidentals" like gaskets, etc. but that was enough $ for now. I wrestled in my mind about trying to do the mods myself but with only one arm I was afraid of getting in a "pickle", so I'm going to have a guy who has been hot rodding Fords at his shop for 30+ years do it. Should be fun! Heads won't be available until Feb and weather may be a moderating factor as well...?
