Malcolm. Use your back arrow. This happened to me. It said it was submitted but it didn't appear. When I submitted it the second time (no retyping) it did appear.

The deal with you young pups is :

You didn't grow up working on pre -war technology so you're not aware of the difference in the technical aspect of it ~ regardless of whenever the final draft was dated , the venerable 'B' series engine remains a solid and good 1940's tech design . :thumbs:

I hope Malcom doesn't give up sharing his pearls of wisdom , I'm still learning and love to hear them :bow: .

Thanks, Steve. He, he.
That was worth the $20.
In baseball, running into someone is apparently a "collision".
But doing the same thing in a car somehow makes it an "accident".

It's people like you, Gary, that makes it hard for me to find tachometers that only read to 4,000 rpm maximum.
Maybe I'm missing out on something, but I try to keep my B motors running at between 1,500 and 3,500 - at the most 4,000 - where they seem quite happy.
I'm with Jimmy here ~ most of my fleet is saved from the breaker's yards and has high milage but since I rarely operate it out of the design parameters , they keep on running mile after mile , year after year whilst my fast freinds are doing the 4th rebuild....

Malcolm, I saw your post but now it's gone. Did you delete it accidentally?

There is also a feature on this forum that can be confusing at times. If you make a post, but someone else submits a post before you're done with yours, then your post will appear only as a preview and there will be a note at the top of the screen telling you that "a post has been made since your reply and you may want to review the new post before submitting yours", or something like that. You need to hit submit again to confirm you want to submit your post.

Since I saw your post and then it was gone, I wonder if a new post appears despite the above feature, and then disappears again if you don't confirm. Hmmm... I'll look into this.

I may disable that "feature" to avoid confusion.

Regardless, it sounds like we're lumping the early version with the later ones being discussed in this thread so its a moot issue. :)

Just to backtrack a bit. All post war Austin engines were developed from the 1947 Austin 16 engine. This was a 4 cylinder OHV engine of 2199cc swept volume. It replaced the 6 cylinder side valve Austin 16 engine. It was enlarged to 2660cc for the Austin A90 Atlantic, which was subsequently used in the Austin-Healey 100/4. The smaller 1200cc, and 803cc engines were basically scaled down versions of this engine. The 1489cc engine which used a redesigned block came out in 1954 for the Austin A50. I don't think that A,B, or C designations happened until after the Austin/Morris merger. The C series was, of course, a six cylinder engine. The six cylinder engine in the MGC is not a C series engine, it is actually an engine designed in Australia for the Austin 3 liter. The original Austin 16 engine went on to be the basis for the 2.2 liter, and 2.5 liter diesel engines. The B series engine was the basis for the 1.5 liter diesel. Those were all successful diesel engines, which says something about the inherent strength of these engines. Of course the best B series engine is the latest MGB engine. All these engines were developed over the decades, and have been really successful engines.

Thanks Malcolm! And thanks for setting wikipedia and that pesky site admin straight. :lol:

Now can we get back to the topic of this thread?? Me,me, my engine. This is L.A. Me, me, me.

Just kidding. Hey Admin! You might want to put Malcolm's text somewhere permanent on your site. Great info.

Hey, I'm still not disputing Malcolm's info. As stated I was only trying to figure out if we were including the early variant with the later one since they were very different engines.

I had never heard of the early version being lumped in with the "modern" B-Series engine before. Learned something new, and was simply asking a question about that info.

Now go work on your car. :hammer:

Your info is spot on Malcom , the venerable BMC 'B' Series engine is indeed a very good 1940's design .
