That time of year

Happy New Year to you all.

A simple one that has got me head scratching. What anti freeze is suitable for SBC iron block with aluminium heads and aluminium radiator

Prestone - yellow in colour, its a 'traditional' old school type antifreeze - either available pre-diluted 50/50 with de-ionised water - or - sourced 'neat' and dilute it yourself 50/50 with the de-ionised water.
Available from most auto factors.

Another vote for Prestone.
