Searching For Engine
I guess I'm looking for a needle in a hay stack,
but I have been desparately looking for a 1985
Mustang 5.0 liter roller cam engine.This is the last year for the carburator engine.$ 1100.00 to $ 1300.00 is a bit much for a long block and then the added cost for all of the other parts needed to complete the engine. I figured if I had to rebuild the stock 240-6 I may as well put
something with a little more power in my 66 F100.
Has anyone done such a conversion? Whats involved
with the carburator linkage?
Thanks!

Just put old bracketry on an 85 5.0, except make sure you use a 82 or later harmonic damper. I had 85 heads on a 80 block in a 76 F100 swapped from a 67 ranchero(not it's original motor) I bought and used an edelbrock performer 289 manifold on the 85 heads. If you aren't running a Thermactor AIR setup then put proper plugs in the end of the heads. The roller cam should't be an issue, except make sure you use the correct kind of distributor gear. You may have issues and need to change engine towers in your 66 (not familiar w/ that vintage) An easier swap might be to use a 300/6 and do some of the performance upgrades to it. Or quit messing around and put a 390 or maybe a 428 FE motor. I believe 66's came stock with a 352FE so if you found a donor you'd have the bracketry and engine perches. If you use an 85 5.0 remember that you must use the proper balancer and flexplate/flywheel, the balance on 302 changed in about 82. The flexplate/flywheel needs a 50oz counterweight.

Don't worry about getting a 1985 engine. You can convert the
later engines to a carb. I changed a 1986 fuel injected motor
to a carb system. I used a Ford 1968 4bbl manifold and a
Holley 600. I had to use an older style timing cover for the
fuel pump. Make sure you install the cam eccentric on front
of the camshaft for the fuel pump. The fuel injected motor had
something that resembled this but it was not two pieces like
the older motors with a fuel pump. I had to drill out two
locating dowel holes on the timing cover to 1/2 inch. The ones
in the later block where bigger. I asked a local engine
builder about the gear issue when I installed the older duraspark
distributor. He said if I was using the factory roller cam not
to worry about putting a brass gear on. Apparently you only
have to use a brass gear with aftermarket billet cams. My engine
came out of a Lincoln Mark VII so it had the regular 302 firing
order. If you use a HO motor it will have a 351w firing order.
Just swap the plug wires around whatever you get. Like others
said, keep the Harmonic balancer and flywheel with the engine.
If you rebuild the motor you will find the later motors take
different pistons and rings. The rings are a new thinner design.
If you don't want to use these you can put older style pistons
and rings (together) in the newer engine. I put older cast flat
tops in mine. I ran it for 8years and it got very good gas
mileage and had good power too. I wanted to use the later model
valve covers but they don't have the pcv valve connections and
such that you need.
