I changed out the water pump housing for a car one with great care and the dimensions were the same. However, the threaded holes in the ends of the heads are not the same. Plus I'm not sure how these power steering brackets go on with another big front balancer on a cast crank with non-AC.

Many Thanks
 
You mean the holes in the ends of the motor home heads are drilled in different locations? Seems odd, but could you drill/tap regular holes where you need them if they're in the wrong place?
 
Are you using a b motor alternator bracket? The rb motor hole is about 5/8” farther out.

Both have 3/8 holes drilled and tapped but on the same end so if you swap them from one side to the other the holes are only in front on the right side of the engine. on the other end is a smaller 5/16 tapped hole. This motor when I got it had the front alternator bracket nothing else. The power steering pump came from an RB engine.
 
I will check on that, thanks.

Here is a 440 bracket redrilled to work on a 400. The distance from the top wp bolt to the 440 alt hole is about 5 1/4” center to center and the 400 alt hole is approximately 4 7/8”.

The top photo is before I drilled it.

The head bolt holes should be in the same place from head to head unless it’s a non factory head.

The only difference is low deck vs high deck changes the distance from crank centerline thus moving the head outward when going from b to rb.

The brackets are different to compensate for deck height difference. Unless you have a dual purpose bracket that looks a lot like the bracket after my modification.
 
Auggie. If you want to come down to Waterville Ohio you can look at my alternator set ups. I have both b and rb in vehicles. I probably have a bb ps pump setup too that I’ll give you.

I’m the guy that came up and compared 2dr rear seats to 4dr rear seats last year. You are welcome to come down any time.

Let me know

I sure keep that in mind the PS one bracket is giving me a little trouble.
 
What year of brackets are you using? Pics?
I've never seen a BB head with 5/16" holes.

I'm I wrong or is the difference between truck and car heads? And there is a difference in the intake valve demention cars are different.

Bought RB brackets. All I needed to do was to relocate and drill a hole, works good. Thanks.
 
So why am I still not working on the car/engine? I had cam bearings put in at a shop in Elyria Ohio as we have no reliable shops here in town. I found this shop who advertised they speak Mopar. They did put in the bearings and they looked good, but they flim flamed me on another machine operation. OK spilled milk no sense in getting into an argument over it I hate have to defend myself off my own turf. So I put the crank and rods/pistons back in the heads, cam and oil pump & oil pan. Filed it up with thirty weight oil and used that oil pump drive shaft tool used for turning the oil pump. The only lubrication going on was at number eight lifters not a drop anyplace else. This was late winter last winter and my projects around the house were not getting done. As well I was so disgruntled at that time I just covered the engine and haven't touched it since. I'm almost finished with the last house jobs now so I'll get back on her soon.

And many thanks for you guys input.
