I changed out my 318 motor with a 360. It has a 4 speed trans with a neutral balance 10.5” clutch. I’m looking for flywheel I can buy that is drilled out for the external balanced 360. Any ideas. I’d rather not drill my old flywheel.
 
And just as a reminder: make sure your 360 crankshaft is drilled for a pilot bushing; or that the pilot hole is at least deep enough for the trans input shaft and use the roller bearing in the convertor register...
 
I ordered a pilot bearing for it but haven’t picked it up yet. I just assumed the crank would have been drilled for either automatic or standard transmission.
Usually not the case. Not all cranks are drilled, some are rough drilled but not to finish size, and if you're lucky you've got one that is finished. If it's rough drilled and not finish sized, run the late model roller bearing in the convertor register. If it's not rough drilled, you've got 3 options: pull the crank and take it to a machine shop and have it finished to spec. and run the standard bushing; rough drill it yourself (does not need to be precise, just deep enough) and run the roller, or cut an inch or so off the input shaft and run the roller. There's lots of individual preferences pro and con between the last two, but those are your choices, and all have been done successfully.
