Want a site from folks that have done LOTS of these 351W swaps?
They did my conversion, and I beat the hell out of my 351 Mustang for EIGHT YEARS! It's real strong, and the very thing that Cobra-R's are based on.
These guys started as mechanics in a suburban Detroit Ford dealership. They do excellent work, and I highly recommend them to anyone. No, I am not related in any way.
I started withmy 1990 GT convertible w/AOD, a Ford crate 351WLightning roller cam short block, added Edelbrock Performer RPM aluminum heads (.202 valves and milled 1/2"), and used many of my 5.0 parts. I kept my EFI, and just swapped injector wires at the harness plug, for the correct fireing order, whichcost NOTHING. I bought a new cowl hood, General Kinetics Cam, A/C bracket, injectors, oil pan kit, Crane rocker arms, larger rocker covers, distributor w/steel gear, flex plate, double roller chain set, longer headers, athree core radiator,and larger intake. Add ARP bolts for a 351 and a gasket set, and it's serious race time!
SAFETY NOTE: This is not a car you let your kids take out on aweekend night. You might as well **** a handgun and let them play with it. It is for good, experienced, drivers, who know their car as an extension of their body. Serious business, do not let just anyone drive it!
It sounds simple enough, but there are a few changes I should have made. I kept the mechanical fan (BIG MISTAKE). After about a year of raising hell and beating everyone up, one day I jumped on it. I got through first, and second (sometimes it happens so fast you can't tell because the tires are still trying to hook), but whenit shiftedto third, the fan twisted the water pump shaft IN HALF,causing the fan to tear a nasty hole in my composite hood. Think about what I just wrote... the engine is doing 6,000 rpm, the trans shifts, and that mechanical fan actsjust likeanother FLYWHEEL, driving the serpentine belt through a little water pump shaft.
The sound was horrible. But the351 suffered NO damage. That mistake cost me a new water pump, radiator, and cowl hood (painted) When I went with an electric fan, all my problems went away, and I continued to tear 'em up every day, for many years.
Today, that 351W is in my 1955 Ford Customline. The Mustang's bodycouldn't take more than 16 Michigan winters,before itrotted away. But buying and converting that engine, was the best (and cheapest) thing I ever did. The fond memory of my 1990 Mustang still live on, every time I startmy '55 Ford.
