Decoding my 454

I found the block casting number on the back of block. It is 3999283. There is a P next to it.

The engine ID code on the front of the block is T0618TRT in big numbers. Beneath that number and to the right a bit are the numbers 04F190496.

What information can we gleen form these numbers? Are there any other numbers I should look for?

Thanks.

It's definatly 3999283. I just went back under the car and double checked it. Can't get a good picture, but I can see it very clearly using a mirror.

Re: Decoding my 454

Doubt it's the 3999293 as :
3999293 = 366 68-85 Truck Tall deck

Also doubt the 3999283 as that doesn't show up.
Heres the 399 series of casting number's for a 454-pick one:
399289 454 73-79 2-bolt
3999289 454 72-78 Car & Truck 2-Bolt

And here's the remaining 399 series numbers:
399293 366 77-78 Truck
3999290 402 72 2-bolt
3999293 366 68-85 Truck Tall deck
3999294 427 68-84 Truck Tall deck

Odd's are it's the 3999289
Post the casting date.
OH ,your part VIN shows it to be from a 74 built in Flint ,so :
TRT = 1974 454 245hp Truck LS-4 VIN Z, C10 or C20

Re: Decoding my 454

Mike,

You're right. It is 3999289. I had to shine a light on it and stick my iphone up there in video mode to finally get a clear picture.

It's a pita trying to take a picture of a reflection in mirror holding the mirror in one hand and the camera in the other.

So it's a 454 made in Flint in 74. Is there any way of knowing what kind of car or truck it was installed in?

Re: Decoding my 454

Read my edit.
I'd need the entire VIN to tell you exactly what it came out of.

Re: Decoding my 454

Trans casting numbers don't tell anything about your block.
Transmissions also have ID's on them.

Re: Decoding my 454

Might as well throw in the cowl tag and vin number too!

The Vin number of the car is 136370A132624.

The cowl tag is below.

What can we tell about this car with this information?

I know. I should have started another thread.

Now let me go see if I can find the tranny ID number.

I'll be back!

Re: Decoding my 454

Here's the best shots I could get of the tranny ID code. It's a real pain trying to get into a position to see those tiny numbers.

I can tell you there's a lot wrong with the car itself. The trim tag body date is 05B or May, 2nd week but the VIN sequence, 132624, is mid February. VIN should be in the 166xxx to 172xxx bracket to be correct or a May-built 70 Chevelle from Atlanta.

Paint color is Cranberry Red w/black vinyl top and 787 trim is red bench seat according to the trim tag.

So it's a 454 made in Flint in 74.
No, the truck the engine came in is from Flint as noted by the partial VIN. The 454 engine was built on June 18 in Tonawanda, NY (T0618). Need to read the replies a bit more carefully.

The car is cranberry red with red interior. But it has bucket seats.
