I'm in the process of doing the swap and can attest to the help from the "Tech Tips." You ought to be able to wire the starter on the 235 the same as the starter on your 216. I think the flywheels are the same, so you can probably swap the starters, too, if that's easier. Since my 235 was bought as a long block, I am using the flywheel, bell housing and transmission that were hooked up to the 216. Lots of sources for the short shaft water pump (I don't recall where I got mine). If you have to drill holes in the front plate (as I did), you will also want to file them square to accept the carriage bolts for the front mount. Good luck - fun project!
