Don't know if it's interchangeable but I doubt you'll get 1800rpm with a 350. You'll probably get more like 2500-2600. I'm thinking that's not a big enough difference to justify the trouble. If you want 1800 rpm you might have to go with a taller gear set yet, which means you might need to have one custom made.

Not much help, I know, but you had me thinking for quite a while.

WELL I WORKED HARD ON THIS ON
THE RATIO ON THE 350 DIFF IS 3,06,[V]
BUT WE CAN USE A DIF FROM A 84 380 W/ RATIO 2,47.[:D]
