1989 alpha one 4.3l

The manual recommends sae40 oil. Is there a better option today? Will a oil filter for a 1989 GM 4.3L do the job?

The manual does say sae 40 for my temp range, but that was 1989. Thought maybe there was a better synthetic alternative. As far as the filter goes, figured since it was a gm 4.3, the standard filter for that engine wld be fine. Don't like giving extra money to the friendly marine dealership.
