Oil change in LT1

Simple question....what grade/weight of oil should I use for my 94' 205, LT1 engine? I can't find it in the manual anywhere, it's not on the oil cap and could not find it in here with a few searches. Thanks!

5W30?
10W30?

I thought I had been told to use 15/40 marine, and Pennzoil PZ-3 (or was it PZ-1) filter.

At the end of the day, I think the main goal is regular oil changes....

I already found the owner's manual a few weeks ago but it doesn't list what weight of oil to use in there (unless I missed it somewhere).

The 1996 manual lists the oil specifications on pg. 63 (pg. 127 of the .pdf). Mastercraft recommends SAE 20-50 racing oil. According to the Indmar manual they recommend 15W-40. I went with Mastercraft's oil and ended up with a spun bearing 40 hours later, so what do I know?

I went to Pep Boys to pick up the oil and they never heard of it. I swung by a Valvoline Oil change place (figuring he should know).....he didn't.....but he did call corporate to find out.

VR1 = Racing oil.

Because this is essentially a GM 350 engine block, why do we need to use racing oil? What would be the difference of conventional vs. racing oil vs. synthetic?

Thoughts on where to get the oil?
