tru-blue 442

Hi all.
I have had this engine for a few years.
I pulled it from a 70 442. correct W-Z's,
Had the coreect OG 400 behind it. Etc...
But it did have a 398662 D2 intake, 68-69
and C heads. I am tring to decipher the pad #.
It is 39M342368. On the back of the block it is
a F-1 unit. Beside the right side of the dist hole are
the number 4 and below that, a little right of that #
is a #43.
Confused yet? Yeah, me too.
Any help is appriciated guys, and thanks again, Adam.

It looks like a 69 455 to me. What was the VIN of the 70 442? What's the VIN number on the tranny?

66-3X2 442

The motor is from a 69 of some kind. The # 4 is the mold # and the 43 is the date code. That appears to be a Feb. of 69 block. If it was from a 70 car,the vin # on the block would be 30MXXXXXX

The 442 has been gone awhile. I had the vin #'s
around here some where, I remember that I ran them
to make sure it was a 344 car, and it was.
I don't know where to check on the tranny, but i still
have it and I can check. I also thought that the engine
was a 69 455, someone will hopefully chime in, Adam.

66-3X2 442

I think the vin is stamped in the pan rail someplace. I could be wrong but that's what I'm remembering.

Thanks 66!
I have met a fella out of Austin
who has aquired a 69 Hurst Olds
and was needing a date correct
block. This one should do it, yes?

I think I remember they are on the pan gasket surface of the tranny.
After you scrape off the gasket, you can see it. Or, uh, well, I CAN"T remember...

vin should be on the vertical just above the pan rail and to the rear of the shifter shaft on the driver's side.at least that's where mine is

Yep, that would do it although the intake would not be correct. The 342368 following the 'M' should be just the basic production numbers that would match the last 6 numbers of the vin of the original car it came from. Although not an original 1969 H/O block, the 342368 does fall into the early portion of the series of vins from 1969 H/O's so the block was around at the same time but probably made it into a Delta 88 or somthing of that nature.

Thanks again for the info guys.
Now my curiosity is up. The engine I have built
for my 69 is a 68 F-2 block. Also 39MXXXX on the pad.
Again by the dist. hole, molding # 2, with a very large
# 204 under that. Does that mean anything?
Also, how can you find where they were forged?

If you haven't found the vin on the transmission yet, here's the location.

The engine I have built for my 69 is a 68 F-2 block.
================
"68" and "F-whatever" on the block's rear face are not significant nor do they indicate the year of [whatever].


Also 39MXXXX on the pad.
================
3 = Olds car
_9 = 1969 Model Year
__M = Michigan assemble plant [Lansing, home of Olds]
___101123 = Vehicle's sequential serial number


Again by the dist. hole, molding # 2,
===============
Mold number, loosely correlated with calendar years since that type block began to be made.

with a very large # 204 under that. Does that mean anything?
===============
204 is the Julian Date of the casting.
204 is about 23July- so July of 1968 for an early production 1969 Model Year would be most likely.


Also, how can you find where they were forged?
=================
They what?
Blocks are cast, not forged.
