Some good info in here about different options. There was a one-year-only Canadian balancer that would bolt on but it sounds like they're very hard to find. I think some guys just run VG33 accessories with a serp rather than going to all that trouble for V-belts.

What damage would oil have done to the VG33 heads?
IIRC someone on here used VG30 heads an a VG33 block because they thought it would be easier than swapping the VG30 cams into the VG30 heads. The passages aren't the same and I think they ended up doing some grinding to sorta fudge the difference. Not the way I'd go.
I haven't heard of any timing differences between the two motors, except that your '89 VG30 will have square-tooth sprockets and the VG33 will be round-tooth. Make sure all the sprockets (and the belt!) are the same style.

The 3.3 pump is superior to the 3.0 pump. (That said the 3.0 pump has kept my family 93 going for 290k on good oil so it is 'good enough' for normal use)
The 3.0 balancer will crack out if you machine it to fit a 3.3 crank.
The producer of the crank pulleys has been under poor health for some time but has every intention of having another production run made when he gets well.
I would have a shop make you a larger aluminum hub that bolts up to the existing pulleys, It does not need to be balanced but the bolts can be upgraded one size for better holding in the softer metal.
Alternatively if someone buys me a lathe and a keyway broach I can make them

Yes, a 3.0 crank will work in a 3.3. Just use all your 3.0 stuff it's been done many times before.
I prefer the 3.3 pump because it flows more and I prefer the front mount filter because you don't spill on the starter or risk burning yourself on the header...
BUT my 1993 has 290k on a stock 3.0 pump with 3.0 filter location and the engine has been been just fine over the last 25 years so I think you'll be just fine.
