In the UK the engine serial number is on the registration document. If you change the engine you are required to send the registration form to the licensing authority to be amended.

A UK registration document will note the following;
Body type, taxation class, engine size (in cc's), fuel type, VIN (aka chassis number), engine number, and color.

Change the engine, convert from petrol to diesel, or paint it a different color, you have to tell the Authority. There is no problem doing any of the above as long as you declare it.

Interesting.

Here in Maine, the Reg. shows VIN, make, model, body style, color, sticker price, and taxes and fees paid (the town takes an excise tax based on the original sticker price of the car every year, in addition to state registration fees).

In NY, it shows VIN, make, body style, color, and weight, as one of the "progressive" changes in NYS law in the 1960s was to base registration cost on the car's weight, under the assumption that rich people drive big cars and poor people drive small cars.

I wish it was like that here. We may not have engine numbers on our registrations, but doing any of the above runs the risk of having to pay a new registration fee (up to 183% of the cars estimated street value) if the authorities deem that the car has "changed identity".

 

455 number on the 2151 intake is away now..

 

That may be UK, but the OP is in Norway. I know that here we don't have any of that nonsense to deal with. US and Canada could care less what engine is in the car when it comes to licensing. 85.00 covers licensing for 1 full year, regardless what kind of car or truck I drive.

 

That may be Canada, but the OP is in Norway.
Just pointing out the differences over here, Allan.
From reading this forum it is apparent that every nation has different requirements. From what I have read it seems Japan has the toughest rules for a modified car, France and Scandanavian countries are also tough, Australia has some odd rules, in the USA it varies, California may be harder than other states, and Canada and the UK are good places for modified cars so far as we can do pretty much whatever we like as long as the result is a roadworthy vehicle.

Oldsmobile diesel blocks also had it in the casting.

 

Yeah, but they used those funny units - "liters" or "litres" or some such thing...

 

If my memory serves me correctly - by no means a given anymore , the Olds diesel engines i owned had "350D" in raised letters on the block.

Roger.

 

5.7 L (350 CID) or 7.5 L (455) actually. IIRC that started back around 76 on Firebirds (6.6 L - 400 CID on the shaker hood). Have you looked at modern production? Everything is done in Litre displacement now.

 

Allan,

That's called humor...

Also Pontiac started using those funny units back in the early 1960s:

 

The block casting number above the water pump had a "5.7L" in it, like the "5.0L" on the 307s.

 

This will be nice on my 407ci gold look-a-like 350ci coloreded engineblock i guess..

 

407?? Not 403?

 

I have an overbored 400 g block. The carb is on a 455 intake btw,
I guess ppl Who like orginal color/setup on the engine are nicer,instead i mess things up on mine just to confused ppl here in my country what engine it is cause of rules around her, hehe. Well, ofcourse its more anonym without any stickers too..

 

I know for sure there is a 350dx on the side of the block.

I think there was also a 350d.

 

Yeah, so change it to what you want

Remember the early 260 block?
They put the CASTING # LAST THREE on the side of the block, which looked a LOT like a CID designation. Durr.... from my database:

550355
"BLOCK, 260 smog era 1976 ? ID = ""5""
Odd practice of placing CN Last 3 [not CID] in huge digits on RH side of the block.
Probably issued with #10 heads. "


I changed a 425 into a 350 so hard that the subsequent owner had to call up and insist that folks looked at all the casting numbers and dammit why did you sell me a 350 when you said it was a 425....

If the local inspector is all you have to convince... put the numbers they want to see on there. Everybody wins.

 

Yeah so, you missed the reason for my post.

 

To wide for be a 350?

The picture was turned..

 

It's easy for someone who knows Olds motors to tell this is a BBO. The small "rib" on the shelf to the driver's side of the oil fill tube is only present on BBO block castings. Also, 350 motors (which first came out in the 1968 model year) used the oil fill tube with the quarter-turn cap, not the press-on cap (which would peg it as a 330 if it really were an SBO).

 

ok,yea i guess so,

 

I found this 68 number in rear of the block, will this tell its an 68 model?
