Paul, Thanks very much. The unit sounds much like the one I got out of a Vintage Air Mini Space Saver unit. I bought the unit and then cut it apart to use most of the components which included a neat coil unit that provided both the evaporator and heater core in one. The vacuum motor driven dampers valves also came in handy for controling introduction of outside air on demand; They have these cute little electric solenoid controllers for the vacuum.
Chris, using the inverted Porsche gives me plenty of room for the valve covers, but using the Jack Roush intake doesn't! I put the Jesel shaft mounts on one of my AFR heads last night and the classic "Powered by Ford" covers fit over them, but stock EFI covers did not. It is going to be a real balancing act to find covers that clear the rockers and the intake at the same time. I am afraid I will end up having to fabricate a set of covers (part of the reason I accidently bought an AC/DC Tig welder the other day; one of those eBay deals where you end up winning the ones you don't really care about ;-)
Regards,
Lynn
