Who knows about the Mk II motor? (re: Bill Thomas)

[markjohnson]

Hot Rod Mag also did a fantastic several page story on these back in 1963 with lots of photos & details.

I have that issue Mark. Along with every other issue from '58-'72.

Jr Johnson probably had the most experience with them.
a few NASCAR teams had them at Daytona in 63 but I think Jr was the only one who ran it for the full season

Here's a little &quot;mystery&quot; reading for those who are interested.

Spoke with Bill Thomas III today. Don't have the answer I'm looking for just yet, but he's got a wealth of information.

The Mark I-IV engine story can get somewhat confusing, but this is what I think it is:

Mk I: The motor in the Z11
Mk II: The Mystery Motor, which was a prototype of sorts to the Mk IV
Mk III: Never produced
Mk IV: The production BBC that came in 1965

Minor corrections:
The MK-I included all the 348s and 409s, and also the Z-11
The MK-II was the mystery motor at 409 cid
The MK-IIs was the mystery motor stroked to 427 cid
The MK-III was only on paper and never developed.

also adding to the confusion is that there was also some 396 MKII engines that Smokey was working on

the 1963 427 Z11 was still used by some top Chevy drag racers in 1964 in the new 1964 Chevelle

there was the MKII mystery engine 1963 427 used in NASCAR Impalas and some Corvettes also built as 409 and 396 cu in

then when the production 396 came out in 1965 it was allowed to run as a 427 in NASCAR
as the early 396 block were made to take the 427 bore

another interesting mystery as mentioned in some articles and in Smokey's books was a 1964 Chevelle 427 test car

I believe Malcom D and Dick Harrell ran their old 427 Z11 engines in their 1964 Chevelles

there was talk about some drag racers getting some MKIIs but don't think it happened
Jr Johnson had to scrape up all the MKII parts he can find to finish the 63 season

In that article, they asked the Chevy engineers if any drag racers ran the MKII and they did not recall any.

They mention the guy with the Z/33 MKII tribute or something drag car but they don't recall it back in the day
