With the modification I'm currently working on, a 235 crankshaft and pistons is going to fit into a stock-appearing 216 block, using modified 292 connecting rods and a camshaft slightly hotter than a Corvette/261 item. It's also going to have a high volume oil pump and a leakproof rear main bearing seal. With a little tinkering on the cylinder head for better gas flow, it will keep up with, or possibly out-torque a stock 235, in a package that looks like the original 216. Given the outrageos prices people are charging to do a stock rebuild on a Babbit pounder these days, the cost won't be much different, as well!
