I'm trying to figure out what type of 351 cu.in. engine is in my 1991 F-150, Cleveland or Windsor. The engine code from the VIN # is "H" anyone have any ideas???

 

H = Windsor

Clevelands were only built for a short time and discontinued long before 1991.

To my knowledge, Clevelands were never put in trucks (by the factory) as they are a higher rpm h.p. motor versus a lower rpm torque motor (like the windsor) as needed by trucks.

Regards,

 

yeah dude its a windsor. 351 clevelands were made from like 70 to 73.

 

Now I gotta get more snort outa it! The K&N filter helped as well as taking off the Cat, should I try and get the ECM reprogrammmed??

 

just get a good 2.5inch dual exhaust system.

 

pfogle, I've put on 2.5 in. "DynaMax" exhaust, it helped a lot, what do you think about getting a new engine module???

 

you could go for a chip, but I would convert to MAF (mass air flow) and put beter heads and a hotter cam in it.

 

Thanks for that, I'm gonna look into it. that's what I keep hearing, "Increase the air flow", so theat's what I'll do!, thanks again!
