I am looking in buying a 1986 F150, to replace my 81 f100 both are 4x4. The guy said that the motor is a 351 HO. I have looked and looked and have not found anything that says there is a 351 ho in pick-ups. Some in the police cars. My question is if the motor is a 351 HO, is it a cleveland or winsor ? Thanks

Ifyou can't get your answer here, you may want to check with sbftech.com There are some really good engine guys over there.

Good Luck!

 

I had one that was swapped into a work van. It's a Windsor engine if I remember correctly

 

Yes they are a windsor engine and yes they did come in trucks. I have seen them in some of the broncos.

 

I had an '85 Bronco with a 351 HO engine. It was a 351 Winsor, not sure what made it the HO, but that is what the air cleaner cover said. It is not an easy motor to find.

check your vin # for a Y to verify it an HO.

 

If I'm not mistaken, the HO had a 4 barrel carb whereas the standard 351 had a 2 barrel. If there were any other differences I'm not sure.

 

It had a 4bbl Holley carb and a marine camshaft. I've seen them in 85-87 trucks. The air cleaner says 351 4V HO

 

Yep, 351W with a Holley and different cam.

 

Roller cam wasnt it??/

 

Thats what I was getting ready to suggest as I recall reading something about the rollercam also.

 

im 99% sure the 302 HO's were roller motors, I dont see why the 351's were'nt. Keep that in mind when shopping for cams and engine parts.

 

No it was not a roller, those didn't appear until the mid 90's. It is a standard flat tappet hydraulic cam with more lift and duration than the standard 351W. It is actually a torque building cam that was designed for boat engines IE: marine cam.
