I found a rv 440 running engine with correct sump oil dip stick and manifolds. crank is drilled for a 4 speed. Will the 383 flywheel work on the 440 ? Save me some coin on a 383 build.

yes if the 440 is internally balanced. Look at the harmonic balancer. If it is thin then it is. Thick balancer = cast crank/externally balanced.

440's didn't come in trucks until around 72-73, not in our Sweptlines.

My grandpa put a 440 in mine. He said he fabbed up the motor mounts, but everything else lined up.

I did this swap and the RV manifolds I had did not fit on the drivers side. Hopefully you won't have that issue. I used motor mounts from a late seventies big block truck and the RV pan worked perfect. Good luck!
