70-78 Ford small-block V8 single belt serpentine conversion
This conversion works for people looking at removing their power steering
setup and air conditioning, leaving only the alternator & water pump as driven
accessories. Trust me: the 302 Mustang II doesn't need power steering!
You may be able to drive the power steering pump with this system, as the crank
pulley does have a v-belt groove behind the serpentine grooves, but I haven't done
it. Please contact me if you get power steering to work with this setup!
In post-79 302 Mustangs, the belt system had been converted
to serpentine and the water pump spin direction reversed. This change (I thought) forced
anyone wanting to convert to serpentine on their early-model 302 to replace
the water pump. Lo and behold the 302's in some non-Mustang cars do NOT have a reverse-spin
pump, yet DO have serpentine systems. Here's the specs on parts I used from a mid-eighties
Ford wagon:
- Water pump pulley: D9AE-85C9-C7A (discontinued)
- Crank pulley: D9AE-6312-07B (discontinued)
- Alternator pulley: Any 6-groove Ford alternator pulley
- Extra spacers: Alternator needs to be spaced out from the engine 3/8" to 1/2". Use
washers or cut up the long bottom-side alternator bracket spacer from
another engine. You may need to use longer alternator bracket and water pump bolts.
- 40" to 42" serpentine belt will work. You may not be able to find a 6 groove belt
in such a short length, 5 groove works fine.
- Use 5-groove belt to make up slight difference in pulley alignment if
needed: Run the belt on the inside grooves of the
water pump & crank pulleys and on the outside grooves of the
alternator pulley.
Also, March Performance carries a billet aluminum serpentine conversion kit for
your MII available through Summit Racing. Ask them to order part number 1675 from March Performance.
This kit includes the crank, water pump and alternator pulley with cover.

K&N air filter
A K&N air filter on any automobile is going to increase horsepower.
Adding one to your Mustang II is simple! Here's the stock replacement part #'s you'll need:
- V8: E-1550 for 1975 and 1976, E-1180 for 1977 and 1978
- V6: E-1350 for 1974 to 1976, E-1280 for 1977 and 1978
- I4: E-1200 for 1974 to 1978

How to change the starter on a V8 Mustang II
- Put the front tires up on ramps.
- Disconnect the battery.
- Use a floor jack with a board on it to raise the engine a little.
- Remove the two vertical bolts that attach the engine mount to the
block.
- Remove the bolt that holds the mount to the frame
bracket, requires a socket and wrench.
- Remove the two lower bracket to frame bolts, socket and wrench again.
- Remove the two upper bracket to frame bolts that go through
the frame. Takes two people or one with monkey arms!
- Jack up the engine a little more and slide the mount and
bracket forward and out of the car.
- Get under the car behind the front wheels and remove the
small crossmember under the bellhousing. Four bolts. A good
set of different shape ratchets and wrenches really helps!
- Remove the lower starter bolt.
- Back to the front. Use a 3/8" ratchet and looong extension
to get the top starter bolt. This is the only way you can get it.
- Slide the starter forward over the crossmember and remove
the wires while its sitting on the crossmember.
- Get it the rest of the way outta there!
- Reverse procedure to install!
Most new starters will drive the bendix in too far, which
can have you doing this all over in as little as two weeks!
There are thin spacer plates available to go between the
starter and bellhousing that cure the problem.

- The "invisible" V6 Oil Filter
You really have to watch the "Qwikie Lube" places if
you have a MII with a V6. The ONLY way to remove the
oil filter is to remove the battery first. Then you
can get to the filter. You can't get it from below.
T-Tops are extra nasty. On the '76 ones, the right
side brace bar is STRAIGHT, and has to be yanked to
pull the battery. In '77, they used a BENT bar.

- Is your V8 302 radiator rotted? Here's a replacement!
Grab the radiator from a 1968 Ford pickup and you'll have an exact replacement
for your V8 302 II. The filler is in the hose, by the way. Some II's had a filler
in the radiator (late 77 and 78). Either will work, you'll just have to switch hoses.
