I have a complete 72 455 engine from what i can tell. Is there anw way to identify if it is from a 442 or W-30? Probably is just a delta 88 engine. The only thing i can come up with is if i take the heads off and measure the valves. Is this correct? the discription is---

Block 396021F near the oil tube
Head Ga 409-100
Head 32M507170
F5 near fly wheel on the back
Near distributor 50
Oil filler tube 246039

I believe it is a 1972 455, what else is there to look for?
It was running good 10,12 years ago then I took it out and it sat in a shed, it is now stuck. I will eventually take it apart inspect it and sell it.
Maybe i should just sell it like it is but what is it worth like this?
Thanks for any of your thoughts.

 

if the "32M507170" is on the forward side of the block below the driver's side head:

3 = Oldsmobile
2 = 1972
M = Lansing, MI
507170 = last 6 digits of the full-size (88/98/CustomCuiser) it came from

 

cool but how do you know full size, not cutlass?

 

1972 at Lansing
A-body started at 100001
B-body started at 500001
Toronado started at 700001

or something close to that

 

Ok at least i know what i am selling now. Thanks

 

What is the very first number on the oil filler tube, providing it is the original to the engine.
If it has never been out of the engine, the very first number is the year of the engine.
But you say it has "Ga" heads it most likely a '72.

Yea, looks like a full size 1972

Block 396021F near the oil tube
Head Ga 409-100
Head 32M507170
F5 near fly wheel on the back
Near distributor 50

Did they use this format in 68 also? I would really like to know more about my engine. Thanks

Pit 69 442 Convert

 

I have a 455 from a 69 delta 88 I took out of the car. If they were doing serial numbers on the heads in I can check that one tomorrow.

 

Won't the distributor number help ID the block (assuming it hasn't been replaced)? I think 442s and W30s got a different distributor than the lesser motors. With this info you could tell if it came out of a 442 or W30. Right?

 

It will, but that's a big ASSumption .

Didn't check the 69 heads for the numbers yes, i'll try to post it tomorrow

 

IIRC

1968 at Lansing
A&B body started at 100001
Toronado started at 600001

 

This is the block from a 1969 delta 88 with a 455 2 barrel center console possi car. Wish I kept that car.

 

trying pics of 1969 delta 455 2 barrel

 

Yep. Those're them.
