What is a tilt valve engine?

that raised identification area will have your displacement, then you can look up the horsepower

the 220 part confuses me i thought the BD engine only came in 240 and 264?

the transmission numbers were 80132 R1
I IH on the side it read as follows 98316-R1 what does all this mean?

the BD came in 220, 240, and 264. the BG motor came in 220, 241, 264, & 265. I don't know what gives the extra inch on them, but this is what is listed. the raised numbers are casting number of the block itself, means nothing, as the block was used for different bore motors,

the stamped in numbers on the ID spot are the ones that count,

your truck had a transplant sometime in it's life, at least they kept it IHC,

I had a L-120 pickup that someone torched a Chebbie 250 into it, did a horrible job and ruined the frame.

only time i would do a engine transplant would be to a V8 for more pulling power

The BD's came in 220, 240, and 264 cubic inches. In the '60's they all would be what was known as a tilt-valve engine[as differentiated from the straight-valve Silver Diamond 220 and 240, and the straight-valve BD 220 and 240 of the mid-1950's]...tilt valve engines having a slightly wider valve cover. The BG engines' primary difference from the BD engines was a sealed crankcase ventilation system and a PCV valve, rather than a breather cap at the oil filler on the valve cover and a road draft tube on the tappet cover. And even though the BG engines were the same bore and stroke as the BD's, they were designated BG-221, BG-241, and BG-265. The valves were tilted off straight up and down, presumably to improve volumetric efficiency.
I Googled your question and this is what I found.

once again proving that nothing International is an absolute, the BG-265 in one of my travelalls has the road draft tube on the block, and breather cap at oil filler.
