Digging up an old thread here.

So if no one has yet made a decent 300 big bore kit, then how about running a 250 cylinder in a 300 engine, using Wiseco 64 or 66mm 12.5-1 comp pistons ?

So the question is will a 2008-12 250 cylinder fit into a 300 engine ? Looking at pics from this comparison strip down, it looks possible.

Anyone got the parts to test / dry fit ?
