V8
Conversion Information
If you have a tired 289 or 302 or need more horsepower and torque, the 351 Windsor
is the way to go. You may get better mileage with a Windsor than a stock 289/302
due to more torque and lower RPM. A 351 Cleveland doesnt have enough low
range torque for four wheeling. Clevelands require very expensive custom radiator,
headers and exhaust. Hard to find 100+ octane gas is also necessary. So, unless
you intend to drag race at 5,000 to 8,500 rpm, a Windsor will out perform, out
pull, out climb, and get better mileage than a Cleveland.
A 69-70 2V or 4V Windsor is best, a 4V having 10.5:1 compression or a 2V, 9.5:1.
Before you swap, see if the 351 has a 3 bolt harmonic bal-ancer. If it has a
4 bolt, youll need a 3 bolt harmonic balancer for a 69 Windsor. If you
cant find a 3 bolt, you can use a 302, 3 bolt balancer by re-marking the
timing marks. Reuse your 302 water pump, pulleys, belts, etc. using the power
steering adapter bracket #3160 & alternator bracket #3161.
The 351W rear main is larger, so the stock 302 pan wont work. An Oil Pan
Kit, #3103, is needed to clear the front differential. Most Windsors have the
sump in front which is bad for four wheeling. Your engine could run out of oil
as youre climbing a hill! Our pan has a rear sump. Even with this pan,
to avoid damage, your Bronco must be lifted 2- 3 1/2.
To complete the conversion, our Headers are designed to take into consideration
the extra 1 1/2 height of the heads. They dont rub the firewall
and if you need to remove the starter, you can leave our headers in place. CAUTION:
Dont try to use your 6 cyl transmission with the V8. There are several
problems and its not strong enough to handle the power.

Oil Pans
These pans are necessary to clear the differential when converting to a
289/302 or 351W. Both are rear sump pans, and require mods to work with
taller-than-stock oil pumps. #3103 contains new pan, pickup tube & screen,
dipstick & tube, and main bearing bolt. #3642 doesnt include dip
stick or tube. Shown in blue, comes black.
#3103 351W Oil Pan, $219.00
#3642 289/302/5.0L Oil Pan, $199.00 |

Power
Steering, Alternator Adapters
These brackets attach the 302 alternator and power steering pump to the
351W heads. They retain stock 302 mounts and use the same belts and pulleys.
#3160 Power Steering Adapter, $16.50
#3161 Alternator Adapter, $16.50 |

Motor
Mounts
6 cyl. mounts must be torched off and these (#3115) V8 brackets installed
in a new location. New rubber mounts (#3114) with safety pins are needed
to prevent radiator damage from engine movement.
#3114 Rubber Engine Mounts, $45.00
#3115 Motor Mount Brackets, $79.00 |
