HELP! Time/temp advice

[Jux]

I am making a cake to welcome home my dd who has been away all week. It is an American recipe (irrelevant, actually).

I should be cooking it in a Bundt or large loaf tin. i have neither, but I do have a smaller (about half size) loaf tin, so I'll do half andmthen the other half.

Temp is 325/160 and time is about 60 mins for the twice as big loaf tin.

How much should I adjust temp/time? If at all!

Ah well, just for the record, it took an hour and a half to cook. Now I'll remember next time I make it. I should also cut the quantities by half.
