I would like to buy a kit and do this myself, but from what I understand the block needs machining for the 347 kit. Does this mean I not only need the crank, and rods, but pistons as well? What about the 331 kits does it need the same machine work on the block? Thanks everybody.

Yes plus the whole mass should be rebalanced along with the damper, crank pulley, flex plate, flywheel, clutch and presure plate.

From what I understand you need the crank, rods and pistons. The pistons are built with the pin offset to take some of the stress away from the cylinder walls. I have a 347 in my 65. It has only been in for a week and I have a few other problems but the motor seems great. I don't know of any special machining needed in the block.

I think the bottoms of the bores have to be notched slightly to clear the rods.
Jazzy, I bet your machine shop did this for you.
One of the recent MM&FF mags show this being done when installing a coast high performance 347 kit in a late model 5.0.
