Hey there. - Just joined so here are some pics of my 1969 Mustang fastback. This'll be the 3rd Mustang shell I put inexpensive Fox Mustang model fuel injection, etc on.
I got it as a bare shell from a towing yard a while back. I swapped in the EFI harness from a Fox Mustang I had and it briefly had the 5.0 in it. It now has a 408 I've been putting together with AFR heads and a Trickflow box intake. The recipe is from a Richard Holdener article that dynoed at ~525 hp.
I had to add a fuel system, tank, wiring, clutch pedal, exhaust, seats, shocks, etc. It runs and I'm tuning it with a Moates Quarterhorse that plugs into the "stock" '89 Ford computer.
Up next - hooking the Fox-style PS pump to the '69 powere steering with a custom pressure hose. Did the same with my '67 coupe - works fine.
