assuming it's a Buick 350, yes it should drop in. you can tell it's a Buick if the distributor is in the front of the engine.
GM engine swapping isn't supposed to have started until the 1977 model year but if it's a late build 76, your car might have gotten one of the 77 motors. and in 77, a Buick could have any of the 4 different make 350s in it.
and does the 76 only have 135 HP?
yes, but that doesn't mean what you think it means. 1976 was rated according to more modern SAE Net Horsepower specs.
1970 was rated according to the Gross Horsepower standard ( which everybody was using at the time ).
so, while the 76 will be down on power relative to the 1970, it's not going to be anywhere near as bad as you might think from just looking at the advertised HP numbers. you need to lop about 1/3 off of the 1970 numbers in order to compare them to a 76 engine.
the hands down most powerful Buick 350 is the 1970 'SP' code 4 barrel but your 76 engine does have some advantages.
you've got the capscrew rods and the large diameter oil pickup and the HEI distributor already. so if you decide to build for power, you've got a leg up over an earlier engine.
