hey thanks you guys Sorry for being so far off on this one. It dosent look like the 240 ford I have in my 67 step side. Everything is on the oposite sides!! I was going off of others input.. it being a chevy???
The Checker Aero bus is so ugly its cool. later down the road I might put a diffretn engine in it. But for now i need to find out what it is so I can get a better carb and fuel pump for it. Like I said it ran but The gas tank was full of hay from sitting so long with out a gas cap.
I do have a stove bolt that came out of a 39 chevy truck. Ill have to look at those numbers just incase any one is interested.

Thanks again for everyones help....
