Bellow you will see ID for 67 400. I am trying to see if mine is this engine - it is bronze and has the # W346006G ANY INFO WOULD HELP

 

The 1967 400 engine was a short stroke 1966-1967 only engine. It featured B and C cast large valve cylinder heads and hydraulic lifters are larger in diameter and push rods are different length and diameter than the standard Olds Rocket V8 it was rated at 350 horsepower and 440 lb/ft of torque with a Rochester 4 barrel and 360 hp with the L69 tri 2 barrel option in 1966 and 360 hp in 1967 it was equipped with a W30 camshaft and outside air induction, 502 factory examples of this engine were produced. They were all painted Bronze and had V and G stamped on the cylinder heads.400 cu in (6.6 L) V8.

The "W346006G" number you posted is the engine unit number and was stamped on the front end of the passenger side head.  That particular number means that at least that RH cylinder head came from a 1967 Olds 330 cu in motor from a Cutlass with 10.25:1 compression.  It would not ever had been bolted to a 400 motor, at least not from the factory. Things can be changed on a car that is over half a century old, so that head may or may not be original to the car or to the block. The actual block ID is a raised cast number located above the water pump, next to the oil fill tube.  Check that number and post it here.  If the block matches the head, the casting number will be 394417 The last "3" will be larger than the other digits.

The block shown below is a 1966-67 400 block.

The 330 is the engine installed in nearly all 1967 Cutlass V8 models.  Only the 442, the Supreme with the Turnpike Cruiser option, or police package cars with the L77 engine option got the 400 motor that year.

Don't underestimate your little 330. They could be had up to 310 hp rating, though that would be a real stretch on modern fuels.
