I finally picked up what I thought was my Dads '62 Super Duty 421. He thought it was when he bought it, but only checked the code on the heads. He bought it in the late '70's in pieces, and never put it together. I brought it home about a month ago, and have been checking everything out. The good news is, the heads are '62 SD 127's, there are a full set of M/T aluminum rods, factory 2 x 4 intake with carbs, and a forged crank. The bad news is that the crank is a 3" main, which means it's not a 421 crank. The block turns out to be a '62 11B 425A 389 4 bolt block. It has an old Mallory magneto. At some point, someone tried to change the block to mount a starter to it (not pretty). I'm not sure that the crank is the stock stroke. The pistons have a very short skirt. I've heard Mickey Thompson sold many different stroke cranks back then. This one has a number stamped on the front counterweight, and an "MTE" cast into the rear counterweight. The heads have been seriously ported with big valves and looks like titanium retainers. I need to check the stroke on the crank. Anyone have a simple way to do this?

More pics. Note the strange piece welded on the rear flange of the crank. Also, I've never seen an oil pump like this.

[Poncho-V]

A few more. The number is 3072 - 2.

The best news is the carbs look like correct 62-63 SD carbs,63 valve covers.Tom

[Poncho-V]

Pistons and rods.

Crank might be a M/T cast stroker crank.Tom

[Bill Hanlon]

The GOOD news is that it isn't a 421 crank, because if it was and it looked like that I'd cry.

The oil pump looks like a SD oil pump pick up.Pics in Petes book.Many 425A engines in 61 were converted to SDs with over the counter parts,would have also been carried over into 62-63.Tom

Take a picture of the crank positioned at 9:00 (nose) and 3:00 flywheel end
and lets see if we see a forging line on the crank.

I hear ya, Bill. All of this stuff was in my Dads barn. In the Texas humidity.

I was around then and I also have a M/T catalog with the cranks in it.I ran one of his stroker cranks in one of our match race engines.We had Nhra and AHRA league engines and then a big CI match race engine.Tom

[Poncho-V]

Also any info about the strange piece welded to the rear flange?

[tom s]

Front carb is missing a fair amount of parts venturies power pistons, and more
A serious engine in its day, Very Interesting

Thanks, was not aware of that. Maybe the reason why Moldex ground a bunch of cranks based on using Kellogg forgings.

I agree, thank God that's not a 990 Crank looking that way!

[tom s]

Actually if a 990 crank it could be "fixed" good as new,a cast crank not so much.Tom
