Since 261 engines are pretty scarce and somewhat expensive when they do become available, how about this - - - - -let's make the much more readily available and less expensive 235 into an engine almost the same size- - - - -and maybe give it a torque advantage over the 261 in the process?

Here's my idea- - - -the same stroke increase that's available by offset-grinding the 261 crankshaft and using 292 connecting rods can be done with the 235 crank, and as an added benefit, the slightly shorter 292 rod will allow the original 235 pistons to be re-used with only a slight bit of machining to keep the pistons from hitting the cylinder head. An added advantage will be a piston deck clearance of zero- - - -not the lower deck height of the stroker 261 with the Cadillac pistons. If the 235 block is bored .080" oversize, the cubic inch displacement comes out to 257- - - -"almost a 261", and with a longer stroke to boot! For the really adventurous, there's a recycled NASCAR tool steel connecting rod that's available on Ebay pretty regularly that would allow an even longer stroke to be used by offsetting the 235 crank journal further than is available by using the 292 rods. I haven't done the math on that one yet!
