On my old 454 I would run until up to temp, then drain the risers and block, then run the pink anti-freeze until it came out the exhaust approx. 3 gallons, then re-drain everything. Never had a problem doing it that way for 15 years.

No offense but if you have to ask that question, you will be farther ahead (especially in your wallet) to pay someone to show you how to do it properly before attempting. It's a real nasty lesson to find out there was water trapped or insufficient non-tox to protect your property.

NY freezes as solid as Anchorage as far as split components
