The best thing to do is purchase a complete 351W engine out of another truck with low miles w/all
the brackets,pulleys,intake,etc.If you can't find
one w/low miles then just get one and rebuild it.
The 351W should fit right in place of the 302.You
might have to make some adjustments on your exhaust where the pipes connect.Also try it with
your existing computer.You may have to change it
out to one for the 351W.One more thing your gas
mileage will suffer as in 2-3 MPG less.I have a
93 and at the present time I'm changing the gear
from a 3.55 to a 4.10 to accomidate my 32" tires.
