You could just change the rotating assembly, sure.....Of course certain engine will like a certain combo of parts...i.e. heads, intake, carb, etc. However, upgrading to a stroker is definitely do-able.

You can just order the whole rotating assembly already balanced, and bolt it in. On long stroke kits, you may have to clearance the cylinder skirts on the block to keep everything from hitting each other. No big deal though. Just call up a reputable parts shop, tell them what components you have, and you could have a kit specially made for you. They will have to know what heads you have so they can get the right compression and valve cuts in the pistons. Also, you'll need to know how your flywheel and harmonic balancer are balanced so you can get a good total balance on the assembly.

The only thing is that if you have 10000 miles on an engine, more than likely there may be a little wear in the cylinders. The cylinders may need to be cleaned up to make sure the rings will make a good seal.
