I read somewhere that a 292 cound be made from a 230 by changing the crank and related parts. If so, since I have a GOOD 230, would it be advisable to do this?

You can if you have a need for the shorter block. It will be VERY expensive. You will need a 292 crank, and a set of pistons from Clifford Performance, and that's just to start. Check the links on the left for Clifford Performance. As Walt said "If you want a 292, get one".

Sorry, Walt.

Ok...ok....ok... I'm not interested now. But I was told I could easily make it a 250 by changing the crank. Now, is this worth the effort and cost?

I have a 1959 261 and want to know what would be the better performer if both had similar modifications.

Thanks fellas'

To make a 230 into a 250, you will need the crank, rods and pistons. The block is the same. If you want to build a hot motor with custom pistons and rods starting with the 230 will work. If you want basically a stocker or slightly modified motor, you would probably find it cheaper and easier to find a complete 250.

If you are planning to install this engine in an older chassis, then the 261 will start with more displacement and make as much or more power than a later 250, and it will be easier to install and maintain in the older vehicle. A 261 will fit easily, without serious modification, wherever a 235 or 216 sat before.

God's Peace to you.

It would Cost you over 1,000 To Put a 292 crank in the 230 Or even a 250. And What You END up with is a LOW DECK 292. That wants to Push The RODs out the side of the Block.

Yes you can put a 250 crank into a 230 and End Up with a 250 As long as you USE either 250 Pistons Or the 307s( should also have the Blocks Line Bore checked when Swapping Cranks) The rods are them same. If your just after a good HOT L6 you can do this with the 230 It self. The 230 has a flat top piston to start with, Over the 250s which is a dished piston. If you want to Bump up the compression Then Have the Head shaved a little and Be sure to Zero Deck The block to piston Head. Pick a cam To best suite what your after. And You must realy Think about the Head work For The combo. Other wise You will be pretty Much just tossing your money away.

not meaning to hi-jack a post, but i read somewhere that the bore of a 230/250 is the same as a 292?

if thats the case, could 307 pistons be used in a 292?

thanks!

The 283 & 307 pistons are very different then the 292 rist pin height. Plus the 292 piston is very tall To look at compaired to a 230,250 So I think it would sit Way to Low in the Bore.
