The 360 build that has more turns than Willow Springs

I have wiped out a few cams. The last one was Summer 2022 and it is strongly suspected to be due to the oil that I used since I ran the engine for years with one type of oil then switched, only to have the cam lose several lobes within a few months.
I hate the anxiety of losing a camshaft. I've decided to swap a roller into my big block in another car and since the last of the LA/Magnum engines already had the roller setup, I see no reason to use a flat tappet block.
The machinist is going to see if the block will clean up going from .020 to .030. He thinks it should. I'm not sure how busy he is so the waiting game starts. I'm looking at either .030 or .040 over pistons but won't order them until I know where the block cleans up.
I wish that I was friends with a dyno operator! It would be great to test the car as is, then test it with the next engine. I have a nice 904 in the car but I don't know if I should trust it to hold up given that this engine should make more power. The roller has more compression, more cam, better intake and I'll use headers and 2 1/2" exhaust. Everything steps up on this one.
I have a nice 727 and a factory high stall converter that I could use, that just means drive shaft and linkage modifications. The axle is an 8 3/4" with a 4.10 SG diff.
