Well, it looks like the 261 block I got will work (see 261 max overbore question). However after having it hot tanked and the bores measured the machinist noticed the rear main cap is cracked. So my question now is will a 235 rear main cap work? I know I can find one of these in the junkyard. Also will a 235 crankshaft work in a 261? I'm guessing the 261 crank is weighted differently. I am going to take the crank in to get it turned and with my luck, something will be wrong with that too.
