So if you cut the stamp section of a 5.0L and then placed the number cut off a 4.5L on with some JB Weld and paint...so you can race in a lower class...that would be bad?

Mark, could you please educate me for a moment? I must be missing something very important, because I can't see the flaw in this plan. The new block was blank....the old block was presumably fubar or else why do it....so who would care exactly? The numbers don't identify the car, such as a VIN does, do they? Just the block itself, I thought?

Stamping numbers into a blank block with "supposedly" the old engine number isn't proper or legal in most states. This is to protect future buyers from buying a car that might be a frankencar made up of different parts from a chop shop operation. Unfortunately chop shop operations are still around and doing a good business.

These stringent motor vehicle laws have also given fits to kit car builders in many states. But they are in place to protect consumers like you. As with every law, there will be proponents and detractors of them.

States are increasing scrutiny.

California insists that this area is just "for official use" and if anyone stamps anything there, you are a criminal. Other states don't care. The Germans really don't care. California can make almost anything more complex than it needs to be!

All replacement engines should have a "DOT" stamp, with a Porsche triangle, for use in this country....and that stamp may not be in this area!

Anything that is smooth and has no numbers is very suspect...don't let the California Highway Patrol see it!

Post pictures of your non-marked blocks. Love to see the variants.

I bet people have been charged with that at some point.

I know a guy that bought a Corvette engine that was replaced with a race motor, the car was stolen soon after that.

The guy I know gets checked at a random roadblock and his motor comes up as stolen......................
It was a big deal to get that all straight.

The reason I am telling this is to show that however unlikely, you can get checked.
I would keep a copy of the bill of sale for the engine in the car and contact the GA DOT to see what they have to say.

It is hard to do the right thing, it changes from State to State.

The picture looks more scraped up than it does to the naked eye, I think it's where I wiped some surface oil residue.



There was a part number on the front of the block just to the upper left of the water pump. Not sure if this is different from a 'normal' block.

Abby Normal

I'm going to heed your councel on that one..

Lots of the parts have "casting numbers" that are not part numbers. That's what you see. Perhaps it could be tracked to a year of production or planned size for the engine.

On mine the boss looks is not machined at all. Just a smooth cast surface like most of the outside of the block.

GregBBRD

That doesn't look like any other that I've ever seen...is it as tall as the others pictured in this thread? I can guarantee that the Califonia Highway Patrol auto theft people would take your car away and try to "raise" an old number, from this area.

You might might want to just ignore this whole issue/remove this entire thread and move on....involving any state agency might create more issues than you want to deal with. Ignorance is sometimes bliss...this might be one of those times!

Abby Normal

That's why I'd never live in Kalifornia..lol

I got the block from Anderson, so I'd just sell him out it there was any sign of trouble

There were never numbers on the block. It was a training block he got from Porsche and was in new condition when I got.

karl ruiter

Here is my factory new block. No numbers and the area where they would go has the same rough cast texture as the rest of the outside of the block.

Roll over on Mark like a puppy would ya.

You block looks like the pad has been machined, Karl's looks as cast.

I really do not think it is going to be a big deal here in Georgia.

Vilhuer

Surface where engine number is stamped was changed from cast to machined some time in eighties. Casting was raised higher and when top of block was machined also number surface got automatically machined to same level as rest of the block. This means its possible to know if number is correct on early block simply by checking that surface is cast. On later block surface must be at exact same level as blocks top and machining tracks must align with surrounding block top areas. Thus on both variations there are ways to see if number has been changed. Or at least its very difficult to change number well enough for everything to indicate it hasn't been changed.

GregBBRD

Yeah, I'm sure that Anderson doesn't need to grind off numbers...he's got more of those things than he can stack up, already. Anderson's problem: "Let me see...which one goes to the recycler for the aluminum, today?"

As I said, the Germans do whatever they want. If you crash a Cup Car and want a new "tub", they make you cut out the chassis number, send it back to Germany, and they weld it into the "new" tub. That is strickly not done, in this country....a new tub would have a new vin! The Germans simply do not care about these trivial details.

A "school" engine block would indeed have an interesting tale to tell. Did it come out of a car that had an engine problem at the factory? Did it come off the engine assembly line? Was it ever on a line? Was it part of the contact with the manufacturer to supply "school" blocks? Who knows.

Try and raise some numbers...there should be instructions on which acid to use, on the internet. Maybe there are some, maybe not....sure would be fun to find out.
