Just got my new to me 1989 f700 dump truck. The vin says K motor,what aer the cubs ? Thanks steve

 

If it's gas most likely 429. If it's diesel 6.6 or 7.8l ford engine unless someone did some swapping.

 

Looking thru sales ads, it seems a VIN of K is a Ford 6.6
Not a bad thing at all.
Here's one:

That was the 5th digit right?

 

Not bad if it's been taken care of. The combo of the ford diesel engine and dump truck meant extra care for the air filters. We used to bore and sleeve an average of 4 or 5 of these a month.

 

It's not.

The VIN engine code for a 6.6 (400 2V) gasser is an S. The only trucks the 400 were installed in were 1977/79 F100/350's; 1978/82 Bronco's; 1980/82 F150/350's and Econolines.

P is the VIN engine code for the 6.6L (401 cid) Diesel.

K = 7.0L (429 4V) as installed in 1979/90 F600 and larger trucks.

K = 1994 7.3L IDI Turbo Diesel.

A = 7.8L Turbo Diesel.

1961/80: The engine code is the 4th digit of the 11 digit VIN.

1981 thru today: The engine code is the 8th digit of the 17 digit VIN.

 

I wasnt going down the 6.6 gasser road, since this was an 89 F700. I wasn't confused, I just dont get in to the VIN stuff too much. Engine swapping makes the 4th digit kind of a moot point, at least for me. No harm, no foul.

 

Thanks for all the help, this is a grat web site.
