I have a 93 F350 351M it was a roofing truck in NY, and has the
reading tool boxes, ladder rack etc.
The odo says it has about 209,000 miles
aside from cosmetic damage from salty roads
and (common it seems) saggy doors and missing interior handles
it seems to run fine
I would like to run straight pipes back from the motor
when I bypass the catalytic converter what else am I going to have to
ie: computer malfunction due to missing emmissions parts
also as I said it runs fine, and none of the check lights are on,
besides just checking the spark plugs, is there any sure way of
estimating the condition of the motor, and how much longer it will do
it's thing untill I have a serious problem?
