you can't make a 194 into a 250 I do believe the bore is to small.
Twisted6: You're right.
One time I had the brainstorm of putting a 250 crank in a 194. Fortunately I forgot about that when reality set in.
($$ for pistons) : )
kooky krispy: The original thought was that no one seems to want a 194. There are a bunch of 250s out there.
The 230 and 250 have same bore, the 194 and 230 have same stroke. 194 crank + 250 block = 230.
This assumes you have some of each in usable condition.
I don't think I'd start from scratch to do this.
