What is the mopar big block making the least advertised power. I'm mainly interested in pre SAE power rating time, industrial, truck, anything goes. I need low power ratings to get a car accepted for traffic use here. Any knowledge?

I think there were some pretty low-powered 400s in the mid '70s. Most horsepower ratings were done to SAE test standards, the test standards varied through the years. Later standards measured net hp, earlier standards measured gross hp, and resulted in much larger numbers. So I don't understand your comment on SAE ratings.
Let's not forget California emissions standards were more strict.
For example, the 1978 California emissions 440 with 4-barrel carburetor had a horsepower of 185hp.
How much lower do you need?

1976 400-2 made 175 hp @ 4000 and 300 lb/ft @ 2400
1976 400-4 made a whopping 185 hp @ 3600 and 285 lb/ft @ 3200.
Oops. Those are SAE numbers.

Are there horsepower/torque limits for street use in Finland?

Your going to want to look at the emission era for the lowest hp ratings. Before 71, the car companies bragged about how much power they could get out of their motors (some were pretty optimistic and the ratings were taken at the flywheel), after 71, they were trying to sound like they didn't have any power (the ratings were taken at the rear wheels, after all the slippage was lost). Gene
The ratings were never "taken at the rear wheels".
The engines were dyno tested, but with functioning accessories, ie water pumps, emission controls, etc and with exhaust and intake restriction.
Drive train losses are not included in the ratings.

Yes, strictly according to rules we can go 30% bigger than the biggest original engine, 25% more power than the most powerful original engine, but you can't have over 1kw/7kg power to weight ratio. I think the '69 361 industrial will fit the bill since the pre SAE numbers are rated to be worth only 70% of "real horsepower" numbers. So, thank you for the information!

Do they actually measure it, or rely on honesty? Interesting notion to limit power to weight for on road traffic.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
