Chain slipping after new chain and cassette

After work last night I replaced the cassette and chain as well as a thorough clean and reconditioned the rear hub. I replaced the existing 8 Speed Shimano HG30 cassette and HG50 chain with an HG70 cassette and an SRAM PC58 chain. It was very late by the time I connected the new chain and thinking back I did measure it against the old chain, but didn't take into account chain stretch and the SRAM power-link. So the new chain is at least one link longer.
On the way to work this morning the chain slipped about 5 times under load. Can this be caused by the chain being too long or is it likely to be something else?
If I do shorten the chain I will have to remove two links so that I can connect the power-link properly. Would this then make the chain too short? OR could the old chain have stretched an entire link; it was very knackered?
Thanks

I'd guess worn chainrings.

A chain stretching more than 1/8th of an inch is quite a lot, so a chain stretching a whole chain link (over an inch) is pretty much impossible. Were the teeth / grooves of the outer casing of the free hub worn in any way?

Dazzawazza: Did you ever solve this? Same is happening with me. Reckon it's the chainrings slipping because they're worn. Have ordered a new Deore triple.

Could be your rear mech is set up slightly wrong or your hanger is bent, or even a simple stiff link.0
