bulkhead block?

Post  gmsmkr on March 11th 2015, 9:22 pm

Hey guys is there another way to tell if a dove block is bulkhead if it does not have the A on the square pad?

Did they make a bulkhead block that was 2 bolt main?

I know these are sorta dumb questions but really can't find any info on them or I'm just not looking in the right place.

I've had a couple boss bulkhead blocks over the years all where 2 bolt and I didn't see anything special on the markings over the regular DOVE-A stuff

Whether or not the "A" is there in the square pad, it can still be a Boss bulkhead block. The thing to look for that is always there,,,, is under the passenger side lifter galley there will be another bulge that is machined off flat, in the area where they would have drilled the passageway for the dedicated oil galley. In other words the same area that has the dedicated oil passageway for the Boss 429 blocks and the A-460 blocks.

Hope this helps,
Charlie

From what I've seen having the "Boss 9" bulkheads or not has nothing what so ever to do with weather or not the block came with 4 bolt caps from the factory it is purely random.

I think so yes. It doesn't make any real difference either way. It is sort of like those old FE blocks that you see which use the 427 rear bulkhead with the bosses for the side oilier and pressure relief.

Could you machine a CJ or SCJ block with boss bulkhead to be a full on boss block to use boss heads and all cant see why someone would do that these days with so many other options out just wondering if it could be done

The boss block is different in other areas too, not just the front bulkhead.
