I have a '74 flatbed dump truck (It might be 2 1/2 ton but not really sure) and it has a 370 4 valve Lima motor in it with a Holley 4 bbl carb.
What is a Lima motor and is the Holley stock?

 

first if it's really a 370 it's not stock in that truck (the 370s didn't come out till 79) it's also not a 4 valve motor, thats probably 4V which stands for 4 venturi carb I.E. 4 barrel. And Lima is the name given to the 370/429 medium duty truck engines after the Lima Ohio plant.

 

Thanks, I had a typo, the truck is an '84 not an '74. It isn't a 4 valve. I just assumed it was because the tag on the grill reads "370 4V"

But, is the Holley stock?

 

The Holley is most likely the original carb...probably a Model 4180, which was basically a Model 4160, List 1850 carb that was significantly modified by Holley for Ford starting in 1979.

Just out of curiosity, does your carb have a governor? I've only ever worked on one F-600, and it's been so long I can't remember whether it was governed or not.

The 4v on the air cleaner just indicates as Dennis said a 4bbl carb.

 

rob said that dennis doesnt usually venture out this way

 

Yes, I stand corrected. I had just read one of the posts from Dennis and had his name stuck in my head. Sorry about that Rob
