hello today sadly my motor seized up on my 1994 olds cutlass cruiser so I've been looking for another motor and i happen to have a 2004 chevy venture van with the 3400 and from what i can tell the blocks are basically the same except the 3400 is bored out more would i be able to take everything off my 3100 and put them on a 3400 bottom end easily without needing to change computers and such i know it run perfectly but I was wondering if this would work at all.. or is there any other easy things to do other then just find another 3100
