What about an increased stroke rotating assembly in the 235, J
With the length of the recycled NASCAR connecting rods I have available for this project, some milling of the 235 block will be required. The same stroked crankshaft can be fitted to a 235 or a 261, as long as you're willing to mill the block down about 1/8" to get the piston close to the top of the block. The 235 ends up around 270 cubic inches, depending on the bore size, and the 261 ends up over 300. When the 216 block is used, no milling is required, but the thrust bearing area of the 235 crankshaft needs to be widened or the main bearing web of the 216 block would have to be narrowed by 3/16". The prototype engine I'm in the process of building up has a widened crankshaft flange.
