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.

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

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?

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 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.

What do you make of this?

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

I'd seriously look at the VIN plate to see if it's been disturbed. People don't normally mess with a trim tag as it's not the legal identification of the car whereas the VIN plate is. I'd check to see if it has been tampered with - check the rivets on it if you can. See http://chevellestuff.net/1970/vin_samples.htm for some examples of the rivets.

Bench to bucket? Not a show stopper here but bucket seats are not 'correct' according to the trim tag. If there's a console, that has also been added.

Here's a picture of the vin number. The plate doesn't look tampered with to my untrained eye.
That's the first Atlanta plate I've seen without the dash pad. Apparently plants had their own way of installing the rivets in the plates. In the examples I have Flint and KC are mounted like yours (assuming the rosette portion is on the underside) while Baltimore tended to have the rosette head on the topside. If you can, feel the underside of the rivet and see if it feels like this looks.



That doesn't guarantee anything of course but your sequence of 132xxx is still between the last reported in January sequence of 128747 and last reported in February sequence of 136997 for Atlanta and the trim tag has a body date of 05B - definately something wrong.

There's also suppose to be a partial VIN stamped on the frame rail, see http://chevellestuff.net/qd/frames.htm for locations where they've been found. Since it's on the top of the frame rail, it's not the easiest thing to find.

I took the dash pad off, just so I could see the rivets. It sounded important.

Here's a picture using a mirror to see the back side of the rivets.

They look like the correct style rivets to me and look like they've been on the dash for some time. Got me why there's a difference between the two. Oklahoma is the only state to my knowledge that considers it a crime to tamper with a trim tag and exterior and/or interior color changes are normally deemed that important for someone to swap a trim tag but maybe that's the case here. :confused:
